OVERVIEW This document provides the technical specifications of the Modbus RTU protocol support included with all Centrilifts Graphic Control System (GCS) control units. All modules within the GCS group utilize the same register address map to facilitate exchanging model types with minimal disruptions to the central SCADA systems configuration.

INTRODUCTION The Graphic Control System products support a subset of the functions of Modicon Modbus Protocol in RTU (or binary) format as described in Modicon Modbus Protocol Reference Guide PI-MBUS-300, Rev C, dated January 1991. Specifically, the supported Modbus function codes are: Read Output Coil Status : Function Code 01 Read Input Status: Function Code 02 Read Output Registers: Function Code 03 Read Input Registers: Function Code 04 Force Single Coil: Function Code 05 Preset Single Register: Function Code 06 Write Multiple Coils: Function Code 15 Write Multiple Output Registers: Function Code 16 This document describes the supported functions and the response to each valid request from the host. It is intended to be used in conjunction with the Modicon Modbus protocol definition and applies to GCS (Graphic Control System) system controller software revision 6.44 or higher. All numeric values shown in the function code request and response examples are in hexadecimal (base 16) format, even when not denoted with an H.

FUNCTION CODE SUPPORT This portion of the document provides examples of each MODBUS function code that is supported by the GCS controllers. For a complete list of register address, refer to table 1 through 4 in this manual.

READ OUTPUT COIL STATUS (FUNCTION CODE 01) Digital output states are read by the host via Function Code 01, "Read Output Status". The first coil of this block reflects the state of the motor contactor or RUN state of the controller. If the motor is shut down Coil 0200 H will be set; if it has been requested to start, Coil 0200 H will be clear. All other output status coils will return their status in the same fashion. For a complete list of the registers, see the tables at the end of this document. Example - Function Code 01 Query: RTU ADDRESS

FORCE SINGLE COIL (FUNCTION CODE 05) Individual digital outputs (coils) are modified by the Modbus host via Function Code 05, "Force Single Coil". The GCS controller has only three physical digital outputs onboard (relay contacts) but many virtual digital outputs that are used to control various processes in the controller. Expansion I/O modules can be connected to a GCS control unit thereby increasing the available physical digital outputs (relay contacts) Example: Function Code 5 Query: RTU ADDRESS

GCS support of user Modbus function code 65 Modicons modbus protocol states that Modbus function codes 65 through 72 inclusive will be reserved for user functions and will not be used by any Modicon products. GCS system controllers use function code 65 to enable the transfer of:

Shutdown history records. Startup current waveform records. Event records. Ampchart records.

In the following documentation, the following data type definitions apply: unsigned char 8 bits, 0 to 255 signed char 8 bits, -128 to +127 unsigned short 16 bits, 0 to 65535 signed short 16 bits, -32768 to + 32767 Pvalue signed short, 16 bits, -32768 to + 32767 PointId signed short, 16 bits, -32768 to + 32767 Time unsigned 32 bits, 0 to 4294967295 When retrieving information from a GCS unit using function code 65, the query will always adhere to the following form: RTU ADDRESS

Where:

rtuAddress is the modbus address of the GCS unit being queried functionCode is always 65 (41 HEX) startingAddress is: 0: to retrieve shutdown history records. 1: to retrieve startup current waveform records. 2: to retrieve event records. 3: to retrieve ampchart data (with 4 minute average plus 4 minute minimum & maximum readings.) 6: to retrieve ampchart data (with 4 minute average plus 4 x 1 minute minimum & maximum readings.)

pointCount is 0 if the packet marks the first packet of an exchange and is 1 if the packet is the continuation of the exchange.

The first four bytes of the GCSs response will always be the RTU address, the function code and a block count. The block count will be positive as long there is un-transferred data within the GCS unit. To signal the last packet, the block count (signed short integer) goes negative. The negative number is to be interpreted as ( 1 * (the number of records within the packet)). For example, if the block count was returned as FFEC hex, convert that value into the decimal equivalent as follows:

FFEC = 65,516 ------ 0x10000= 65,536 ------ 65,516 65536 = -20 ------ -20 * -1 = 20 records The following describes the data dependant responses by the GCS controller to Modbus 65 packets.

SHUTDOWN HISTORY Shutdown history data is transferred in a packet formatted as:

typedef struct { unsigned char rtuAddress; unsigned char functionCode; signed short blockCount; shutDownHistory data[HISTORY_RECORDS_PER_PACKET]; unsigned short crc; }aHistoryResponse;

where, HISTORY_RECORDS_PER_PACKET is 10 . The structures data, of type shutDownHistory is organized as:

typedef struct historyTag { time_t timeStamp; PValue ampsA; PValue ampsB; PValue ampsC; PValue voltAB; PValue voltBC; PValue voltCA; PValue analogIn1; PValue analogIn2; PointId causeOfShutdown; PointId lockout; }shutDownHistory;

where,

ampsA, ampsB and ampsC are the three phase current at the time of the decision to shutdown. VoltAB, voltBC and voltCA are the phase to phase voltage at the time of the decision to shutdown. AnalogIn1 and analogIn2 are the value at the analog inputs of the GCS system controller. CauseOfShutdown is a number indicating why the shutdown happened. Lockout is a number indicating if the motor start was locked out because of the shutdown.

Note: The CauseOfShutdown and Lockout numbers are defined in Table 5. The timeStamp is a signed 32bit integer that holds the number of seconds since January 1, 1970 and can be de-coded using the library routines supplied with most C compilers.

Convert the hexadecimal values into decimal notation and history record #1 in the above example yields the following information: Shutdown occurred on April 23, 2003 at the time of 10:04:29. (Time integer value: 3E A6 65 2D hex.) The three phase currents were: Phase A = 79 amps (004F hex)

Phase B = 78 amps (004E hex) Phase C = 80 amps (0050 hex)

The three phase volts were: Phase AB = 481 volts AC (01E1 hex) Phase BC = 484 volts AC (01E4 hex)

Phase CA = 483 volts AC (01E3 hex) Analog input #1s value was: 1150 (047E hex) Analog input #2s value was: 300 (012C hex) The cause of shutdown was: Overload (point ID # 175) (00AF hex) The cause of lockout was: Overload Lockout (point ID # 173) (00AD hex).

STARTUP WAVEFORM Startup waveform data consists of the three motor currents and voltages sampled at 600 readings per second for 2 seconds after the start of the motor. The response packet composition for this data is:

typedef struct { unsigned char rtuAddress; unsigned char functionCode; signed short blockCount; highSpeedTrend data[TREND_RECORDS_PER_PACKET]; unsigned short crc; }aStartupWaveformResponse;

where TREND_RECORDS_PER_PACKET is 20 The structures data, of type highSpeedTrend is organized as:

typedef struct HSTrend { PValue ampsA; PValue ampsB; PValue ampsC; PValue voltAB; PValue voltBC; PValue voltCA; }highSpeedTrend;

where,

ampsA, ampsB and ampsC are the instantaneous values of the three phase currents and VoltAB, voltBC and voltCA are the phase to phase voltage at the time of the sample.

To fetch the time at which the motor was started, build a request packet with its startingAddress field set to 1 and its pointCount set to 1. The GCS units will return a packet formatted as typedef struct { unsigned char rtuAddress; unsigned char functionCode; signed short blockCount; time_t timeStamp; unsigned short crc; }aStartupTimestampResponse;

Example - Function Code 65 (Startup Waveform Records) First, send a message with a point count of -1 (FFFE hex), to retrieve the start time of the last motor start. Query: RTU ADDRESS

As illustrated in the example above, the GCS responded with a block count of FFEC hex or -19 decimal. This indicates that there are no more un-retrieved waveforms packets and that this message contains the normal 20 records The instantaneous values of the current and voltage can be graphed by using common PC software such as MS Excel spreadsheet.

EVENTS Event data is transferred in a packet formatted as: typedef struct { unsigned char rtuAddress; unsigned char functionCode; signed short blockCount; anEventRecord eventRecord[EVENT_RECORDS_PER_PACKET]; unsigned short crc; }anEventRecordResponse; where, EVENT_RECORDS_PER_PACKET is 20 The structures data of type anEventRecord are organized as: typedef struct { time_t timeStamp; unsigned char EventType; unsigned char Exponent; PointId PointIdent; PValue ValueBeforeEvent; PValue ValueAfterEvent; }anEventRecord; where, the field EventType is a numeric that identifies the event. Exponent is a number used to locate the decimal point when displaying the before and after values. PointIdent is a number describing an entity associated with the event. ValueBeforeEvent is the entities value before it was changed. ValueAfterEvent is the entities value after it was changed. Note: The event type numbers are defined in Table 6. Query: Retrieve the first packet of event history by setting the point count to 0000H. RTU ADDRESS

Response: (First packet of event history, only the first portion of the reply is shown)

The time integer 3EA67A4F converts to April 23, 2003 at 11:34:39 am. The Event type is reported as a 02 which is defined as an Alarm return to normal or Alarm_RTN The exponent is reported as a 00 which means there is no decimal point in the value. The Event Point Identifier is reported as 00A7 or 167 decimal. Table 5 lists Point ID 167 as being Overload Alarm. Since this event had no data values associated with it, the before and after values are left at zero. Query: Continue to retrieve the next 20 event records by setting the point count to 0001H, until the block count in the reply turns negative as shown in the example below. RTU ADDRESS

AMPCHARTING The GCS motor controllers record the motor current present of Phase B of the power system. This current data is sampled at high speeds and converted to RMS values. The high speed values are averaged over a four minute period and the minimum and maximum values are recorded in each 1 minute portion of the four minute period. There are two tables of amp chart data that are available via the function code 65. The first, accessed with a starting address of 3 in the function code 65 query is comprised of four minute packets containing the minimum, maximum and average current during each time period. The second table, access with a starting address of 6, is comprised of a single four minute average and four one minute minimum and maximum values. The second table contains more data and is correspondingly longer. The following will describe the two methods separately. Ampchart: Four minute average, minimum and maximum values The ampchart data consisting of four minute averages and minimum / maximum values is accessed using a starting address of 3, within a Function Code 65 query. This Ampchart data is transferred in packets formatted as: typedef struct { unsigned char rtuAddress; unsigned char functionCode; signed short blockCount; aFourMinuteAmpchartRecord data[FOUR_MINUTE_AC_RECORDS_PER_PACKET]; unsigned short crc; }anAmpchartRecordResponse; where, FOUR_MINUTE_AC_RECORDS_PER_PACKET is 24. The structures data, of type aOneMinuteAmpchartRecord, are organized typedef struct { time_t timeStamp; PValue average; PValue minimum;

PValue maximum; }aFourMinuteAmpchartRecord; the field of this structure are defined as: timeStamp is the time of the current recording.. Average is the average of the current over a four minute period. Minimum and Maximum are the lowest and high currents measured during the four minute period.

Query: Retrieve the first packet of four minute ampchart records by setting the point count to 0000H. RTU ADDRESS

Output Frequency Control via Modbus The Electrospeed GCS is a variable frequency controller and as listed below, has three methods of controlling its output frequency. Keypad Frequency Setpoint In this method of speed control, the user enters a desired output frequency, and the drive will ramp its output up or down in frequency to achieve the setpoint. Analog Follower Frequency control In this method of speed control, the GCS drive is provided with an analog signal to one of its analog inputs. The drive reads the present value of this signal and retrieves the zero and span values associated with that input. The present value of the analog signal is converted into a percentage of full scale value by the following function: Percentage of full scale = (Present Value of input / full scale value of input) * 100 Next the GCS drive's High Speed clamp and Low Speed clamp settings are determined. The Low Speed clamp is designated as 0 % speed, while the High Speed Clamp is designated as 100% speed. The controller then calculates the actual frequency value that corresponds to the percentage of full scale and uses that value as the desired output frequency. Additionally, the drive can be set to react in forward or reverse. In forward acting, as the analog setpoint signal is increased, the drive frequency increases. In reverse acting, as the analog setpoint is increased, the drive frequency decreases. Proportional, Integral, Derivative (PID) Frequency Control In this method of speed control, the GCS drive is provided with a setpoint signal and a feedback signal. Using the industry standard PID control algorithm, the drive will increase or decrease its output frequency in order to cause the feedback signal to equal the setpoint signal. In this control method, the setpoint signal can be a manually entered value or a varying analog signal. The feedback signal must be analog signal. In this control mode, the drive can also be set to forward or reverse acting as described in the previous Type 2. To calibrate or tune the drive's reactions to varying input signals, the user can enter gain factors for each of the proportional, integral and derivative terms of the PID algorithm. Modbus access to the speed control parameters: The GCS drives provide support for Modbus RTU protocol. Using this communication capability, the user can modify the variables using the following modbus address registers. Control Type: Modbus Address 40811 (0x032A) Keypad Frequency Setpoint = Modbus Address 40811 = 1 Analog Follower mode = Modbus Address 40811 = 2 PID Control mode = Modbus Address 40811 = 3 KEYPAD FREQUENCY MODE If Keypad Frequency Setpoint is selected, (Modbus Address 40811 = 1), the user can set the frequency by writing 10 times the desired value (in decimal) to Modbus address: 40784 (0x030F). For example: to set the frequency to 59.5 Hz, write the value of 595 to address 40784 to set the frequency to 22.9 Hz, write the value of 229 to address 40784

ANALOG FOLLOWER MODE If Analog Follower Mode is selected, (Modbus Address 40811 = 2), the user can configure which analog input is used as the setpoint and whether the controller is forward or reverse acting. Setpoint input for Analog Follower mode is located at Modbus address 40761 (0x02F8). This setpoint can accept the following decimal values: OnBoard Analog Input #1: 42 (Modbus address 40761 = 42 decimal) OnBoard Analog Input #2: 67 (Modbus address 40761 = 67 decimal) Expansion I/O Module 1, Analog Input #1: 1213 (Modbus address 40761 = 1213 decimal) Expansion I/O Module 1, Analog Input #2: 1214 (Modbus address 40761 = 1214 decimal) Expansion I/O Module 2, Analog Input #1: 1215 (Modbus address 40761 = 1215 decimal) Expansion I/O Module 2, Analog Input #2: 1216 (Modbus address 40761 = 1216 decimal) Expansion I/O Module 3, Analog Input #1: 1217 (Modbus address 40761 = 1217 decimal) Expansion I/O Module 3, Analog Input #2: 1218 (Modbus address 40761 = 1218 decimal) Trident Channel #1: 770 (Modbus address 40761 = 770 decimal) Trident Channel #2: 771 (Modbus address 40761 = 771 decimal) Trident Channel #3: 772 (Modbus address 40761 = 772 decimal) Trident Channel #4: 773 (Modbus address 40761 = 773 decimal) Trident Channel #5: 774 (Modbus address 40761 = 774 decimal) Trident Channel #6: 775 (Modbus address 40761 = 775 decimal) Trident Channel #7: 842 (Modbus address 40761 = 842 decimal) Trident Channel #8: 843 (Modbus address 40761 = 843 decimal) Controller direction: The controller is set to be forward acting by writing Modbus Address 45822 (0x16BD) = 0 The controller is set to be reverse acting by writing Modbus Address 45822 (0x16BD) = 1 PID CONTROL MODE If PID Control mode is selected, (Modbus Address 40811 = 3), the user can configure which analog input is used as the setpoint, which analog input is used as the feedback, the values of proportional, integral and derivative gains and whether the controller is forward or reverse acting. Setpoint input for PID Control mode is located at Modbus address 40762 (0x02F9). This setpoint can accept the following decimal values: OnBoard Analog Input #1: 42 (Modbus address 40762 = 42 decimal) OnBoard Analog Input #2: 67 (Modbus address 40762 = 67 decimal) Expansion I/O Module 1, Analog Input #1: 1213 (Modbus address 40762 = 1213 decimal) Expansion I/O Module 1, Analog Input #2: 1214 (Modbus address 40762 = 1214 decimal) Expansion I/O Module 2, Analog Input #1: 1215 (Modbus address 40762 = 1215 decimal) Expansion I/O Module 2, Analog Input #2: 1216 (Modbus address 40762 = 1216 decimal) Expansion I/O Module 3, Analog Input #1: 1217 (Modbus address 40762 = 1217 decimal) Expansion I/O Module 3, Analog Input #2: 1218 (Modbus address 40762 = 1218 decimal) Trident Channel #1: 770 (Modbus address 40762 = 770 decimal)

If the Manual Setpoint Value is selected, then the actual setpoint value is written to Modbus address 40662 (0x0295). For example, if the manual setpoint value of 1595(decimal) is desired, write to Modbus address 40662 = 1595 Value of Manual Setpoint == Modbus address 40662 (0x295) Feedback input for PID Control mode is located at Modbus address 40763 (0x02FA). This setpoint can accept the following decimal values: OnBoard Analog Input #1: 42 (Modbus address 40763 = 42 decimal) OnBoard Analog Input #2: 67 (Modbus address 40763 = 67 decimal) Expansion I/O Module 1, Analog Input #1: 1213 (Modbus address 40763 = 1213 decimal) Expansion I/O Module 1, Analog Input #2: 1214 (Modbus address 40763 = 1214 decimal) Expansion I/O Module 2, Analog Input #1: 1215 (Modbus address 40763 = 1215 decimal) Expansion I/O Module 2, Analog Input #2: 1216 (Modbus address 40763 = 1216 decimal) Expansion I/O Module 3, Analog Input #1: 1217 (Modbus address 40763 = 1217 decimal) Expansion I/O Module 3, Analog Input #2: 1218 (Modbus address 40763 = 1218 decimal) Trident Channel #1: 770 (Modbus address 40763 = 770 decimal) Trident Channel #2: 771 (Modbus address 40763 = 771 decimal) Trident Channel #3: 772 (Modbus address 40763 = 772 decimal) Trident Channel #4: 773 (Modbus address 40763 = 773 decimal) Trident Channel #5: 774 (Modbus address 40763 = 774 decimal) Trident Channel #6: 775 (Modbus address 40763 = 775 decimal) Trident Channel #7: 842 (Modbus address 40763 = 842 decimal) Trident Channel #8: 843 (Modbus address 40763 = 843 decimal) Note: Take care that both the setpoint and feedback inputs do not contain the same value.
