Section 1 - Introduction

General GroupStart is a functional unit for starting several objects in a predefined sequential order and

stopping them in the reverse order in ControlIT, to be operated from 800xA System. GroupStart comprises two function blocks, GroupStart1 and GroupStart2.

GroupStart1 is the main function block with common control logic and connection to operator interface. GroupStart1 is designed for up to 10 objects.

GroupStart2 is an extension of GroupStart1. GroupStart2 is designed for up to 5 objects. Several function blocks of GroupStart2 can used to expand the number of objects in the group to a maximum of 125 objects. They are linked together with parameter ExParOut and ExtParIn. The order they are linked decides the start order. GroupStart1 can perform a complete function independently, but not GroupStart2.

GroupStart has the following functions and properties: Different control modes, set by operator or by control logic Interlocks function Start & stop control Step and sequence time supervision Alarm & Event detection and handling

Section 3 - Function

Control Modes There are three different control modes are available in priority order: Local, Man and E1.

Active mode is indicated on the faceplate and object display. These modes can also be blocked individually from operator access. When groupstart is in one particular mode, control from other location is blocked. Local Mode

The groupstart is controlled from a local desk or panel. Local mode can be activated by setting the input LEnbl of the function block.

When groupstart is in Local mode, control from other location is blocked. When the groupstart is leaving Local mode, it will resume the last control mode from operator station.

The groupstart is started with a rising edge pulse to L1 and is stopped with a rising edge pulse to LStop. A rising edge pulse to LHold will hold the groupstart in the current position. Manual Mode

In this mode the operator directly start and stop motor from the faceplate button Start and Stop. As long as LEnbl is not active, Manual mode can be activated from the Man button on the faceplate or with a rising edge pulse to the input SeqMan of the function block. Groupstart can be hold from the faceplate button Hold. E1 Mode

The groupstart is controlled from external signals, i.e.: a process signal. As long as LEnbl is not active, E1 mode can be activated from the E1 button on the faceplate or with a rising edge pulse to the input SeqE1 of the function block.

The groupstart is started with a rising edge pulse to E1Start and is stopped with a rising edge pulse to Stop.

The table below describes the commands at the different control modes of GroupStart1. Order Local Manual E1 Input L1 Start - - Input LHold Hold - - Input LStop Stop - - Operator start - Start - Operator hold - Hold - Operator stop - Stop Stop Input E1Start - - Start Input Stop - - Stop

3BTG811792-3025 / A

Interlocks The groupstart control can be interlocked by signals from the process or control logic.

Interlocks are active when the value is False. The interlocks are divided into two groups with the following designations and functions. Process Interlocks

Process interlocks are used for normal process interlocks. There are 4 process interlocks available: IB1 - IB4. All can be configured to accept blocking by the operator. Sequence Interlocks

Sequence interlocks are used if the group is to be interlocked against other objects such as a group start or other conditions in an automatic sequence. There are 2 sequence interlocks available: IA1 and IA2. These interlocks are configurable as blocked or not when groupstart is not in E1 mode.

If IA blocked when not Ext is equal to 1 Groupstart is interlocked if IA1 or IA2 is 0 and the groupstart is in E1 mode

If IA blocked when not Ext is equal to 0 Groupstart is interlocked if IA1 or IA2 is 0 and the groupstart is in Local, Man or E1 mode.

Ready for Start Ready for Start means all condition is cleared for groupstart to start. There are no Process

interlocks, Sequence interlocks are not included. All connected objects are ready and all connected objects are not blocked.

Ready for Start is indicated by the output parameter RFS in the function block.

Object Connection Each object which will be started and stopped by the groupstart shall be connected to three

input parameter and two output parameters in GroupStart function block.

Input parameter Blk_x is used for blocking an object. If the value is True, the step x will be ignored during starting and stopping of the groupstart. It will be bypassed without any step delay.

Input parameter RFS_x is used to indicate that the object is ready for start. All objects that are not blocked must be ready for start. This is indicated by the output parameter AllReady.

Input parameter Run_x is used for running feedback of the object. It shall be set to True when object is running and False when object is stopped.

Output parameters Start_x and Stop_x are used to send start or stop pulse order to the objects. The output will remain True only when the step is active.

GroupStart1 is designed for up to 10 objects. GroupStart2, an extension of GroupStart1, is designed for up to 5 objects. Several function blocks of GroupStart2 can used to expand the number of objects in the group to a maximum of 125 objects. They are linked together with parameter ExParOut and ExtParIn. The order they are linked decides the start order.

3BTG811792-3025 / A

The following example can be used to connect up to 20 objects. The GroupStart1 is connected to 10 objects with step no 1 to 10. The first GroupStart2 in the middle is connected to 5 objects with step no 11 to 15, while the last GroupStart2 is for 5 objects with step no 16 to 20.

Start and Stop Start and stop commands may come from faceplate button or input parameter, depending on

the selected control mode.

When groupstart is starting, it will send command to start the objects in the increasing order, from the first object to the last object. First object will be started immediately without delay. After running feedback is received, it will then wait for a period of time configured in start delay time before continue to the next step. If the object is already running, the next step will be entered without step delay.

But while groupstart is stopping, it will send the command to stop the objects in decreasing order, from the last object to first object. Last object will be stopped immediately without delay. After stop feedback is received, it will then wait for a period of time configured in stop delay time before continue to the next step. If the object is already stopped, the next step will be entered without step delay.

The position of groupstart is indicated by the position number Pos when it is starting or stopping. When the last object has started, the output parameter Run is activated and the Pos value is back to zero.

A running groupstart can be restarted. An object which is blocked earlier but has become ready for start will be started. Objects which already started will be bypassed without delay time.

A starting or stopping groupstart can be hold. The groupstart will stay at the current position. It will leave hold condition when a new start or stop order is issued.

Reset can be performed on starting or stopping groupstart. It will reset the groupstart position back to zero. Reset can be activated from the Reset button on the faceplate or by setting the input Reset of the function block.

EStop order can be activated from the faceplate button EStop. It will override the start and stop order. It will stop all the objects at the same time and set the output parameter Stop_x for duration defined in the EStop Delay Time.

Interaction Window Interaction Window is used to configure the object’s parameter in the Control Builder. It is only

accessible when Control Builder is in Online mode by right clicking the function block.

The main Interaction Window shows the name and description of the function block. The buttons are link to open the sub-window.

1. General Par Name and Description can be entered from interaction window or from the function block

parameters directly. After performing Name Uploader, these values will be used as Object Name and Description and shown in faceplate.

Class defines the process section or area in which alarms are grouped. By utilizing Class, the alarms can be filtered. Valid values are 1 - 9999. Severity defines the alarm priority for general alarms. Valid values are 1 - 1000 where 1000 is the highest priority.

2. Order Block & Init Mode Order Block is used to prevent operator from giving an order of certain activity. The faceplate

button will be dimmed if order block is activated (set to 1).

Init Mode defines the initial mode of the object when cold download is performed. By default, the init mode for GroupStart is Manual mode.

3BTG811792-3025 / A

3. Alarm & Event Alarm Configuration is used to configure how to present status changes of certain conditions.

Alarm Configuration can be set in 3 different ways: 0 = No alarm or event will be generated 1 = Alarm and event will be generated 2 = Only event will be generated

Event Block is used to block the event message generated due to changes in value from logic connection. To enable event for selected message, press the button to set the value to 0.

The text message for each alarm / event is stored in the AE Translator aspect. List of events for all operator activity is managed in 800xA system with Audit Trail functionality.

4. Interlock Setting When Block Event is disabled (set to 0), changes in value of the interlock will generate an

event message. The text message for each event is stored in the AE Translator aspect.

Enabling the Opr Block (set to 1) will give operator the possibility to override the interlock(s) from faceplate.

By configuring IA Blocked when not Ext to 1, IA interlocks will not be monitored when the object is not in E1 or E2 mode. By setting the value to 0, the IA interlocks will be observed in all modes.

5. Timer Setting It defines the delay time for Estop and the maximum sequence time. It also covers the setting

for Start Delay, Stop Delay and Alarm Delay from Step 1 to Step 10.

6. GroupStart2 Time Setting It covers the setting for Start Delay, Stop Delay and Alarm Delay from Step 1 to Step 5 of

GroupStart2.

Text Configuration Text Configuration aspect is used to define the text properties of the object, such as

interlocks and info texts. It is accessible in the Control Structure. The length of the each text should not exceed more than 50 characters.

3BTG811792-3025 / A

Step Name Configuration Step Names Property Translations aspect is used to define the step description. It can be

associated with an object name or any descriptive text. These texts will be shown when the GroupStart is running in the respective step.

Each step supports the following text: Current Step text, Next Step text and Previous Step text.

Select one of the properties, i.e. CurrStep. Enter the text in the column Text when true next to each step number. Before proceed to other properties, click on the Set button. Copy these texts to other properties, NextStep and PrevStep. Once completed for all properties, click on the Apply button to save these texts.
