3.3 Date and TimeAccess to the date and time settings window can be gained by following the menu sequence shown below:
3.4 Protecting ProgramsZEN has a password function, used to prevent incorrect use of the ladder program or to prevent manipulation of settings made by the controller.
The password code may comprise the range 0000 to 9999 (4 decimal numbers).
The password prevents entry to the following points:
Editing ladder programs
Monitorng ladder programs
Changing or erasing the password
Setting the input filter
Setting the node number
The Password screen is displayed immediately any of the different options is selected from the menu. If the password is correct, access to the

3.7 Stabilizing Input OperationsIf the ZEN external input fluctuates, it is possible that the operations will be unstable. To solve this, ZEN is able to filter inputs to stablilize thesignal.
The input filters can be set separately, either for the CPU inputs or for each I/O expansion unit.
Note: The input filter time settings are as follows:

I/O Bit AddressingThe bit input addresses 10 to 15 and the bit output addresses Q0 to Q3 are always allocated to the CPU unit.
Up to 3 I/O expansion units can be added, allocating these I/O points to the X0 to Xb input bits and Y0 to Yb as output bits, remembering the orderof the connected expansion units.
Note:
When the I/O expansion unit does not have I/O points, such as a 4-point input or output unit as shown above, the unused bit addresses are notallocated in the unit and can be used for the following expansion unit.

Once the line has been inserted, the cursor is situated on the right of the program line and the output relay is entered:
Press "OK (1)" again to enter another N.A. contact in series with the previouscontact.
Press "ALT(7)" to select the N.C. input.
Use the "(4)" key to move the cursor and press " (5)" to change the bitaddress to 1.
Press "OK (1)" to enter another new N.A. contact in series with the previouscontacts. This creates the automatic connection between the first two contacts
entered.
Press "ALT(7)" to enable entering the connection line option.
The connection line is definitively set up with the "(4)" key.
Press "OK (1)" to enter an initial Q0 output. The output type can beselected using the "(5)" and "(2)" keys.
Press "OK(1)" twice to confirm writing Q0 output. The cursor will auto-matically go to the next line of the program.

7 Programming Functions
7.1 Timers (T) and Holding timers (#)ZEN has the capacity to use 8 normal timers and 4 holding timers.
Timer Operation (T0 to T7)
Note: The 'n' code means 'null' (blank code on the console)
Timers The present value of the current timer is reset when ZEN switches from Runmode to Stop mode or when the power supply is turned off.
Holding Timers The present value of the t imer will be maintained even when ZEN switches fromRun mode to Stop mode or when the power supply is turned off. The time willcontinue running when the input 'trigger' is in ON mode again. The ON status ofthe timer bit will also be maintained.It is only supported by the holding timers at connection.
Timer Type Operation Applications
X Timer atconnection
Output is activated whenthe set time elapses onthe input being triggered.
Delay operations in On-status
n Timer atdisconnection
Output is activated fromwhen input switches toON mode until the settime elapses.
Useful for timers, lighting orventilation fans
O Flashing pulsetimer
The set timer bit switchesthe selected time to ONmode when inputchanges from OFF modeto ON mode.
Useful for repetitiveoperations when theoperation to be carried outrequires the same time period
F Flashing pulsetimer
The set timer bit switchesrepeatedly from ON modeto OFF mode, while inputis in ON mode

7.1.3 Parameter Monitoring on 'Screen Display'
7.2 Using Counters (C)Up to 8 counters can be used in incremental or decremental mode. The present or current value (PV) of each counter and the status of the bits ofeach counter (ON/OFF) are maintained even when the operation mode changes or when there is no power supply.
The counter bit switches to ON mode when the count value (PV) exceeds the set value (present value = set value). The counter is reset and itscorresponding bit turns to OFF mode when the reset input is activated (ON mode). The count input is not effective while the reset input is active.

8.1 Error MessagesThe following table shows the list of error messages which can occur in the unit when there is an error:
Powered CPU but not in RUN mode
Note: I/O Verify ErrorI/O (X/Y) bits in I/O expansion units: non addressable bits have been used.
Analog comparators (A): used with AC power supply.
Weekly (@) / Calendar (*) Timers: used in ZEN without clock/calendar function.
Display function (D):
The converted analog values (14/15) for AC CPUs are specified as in the list.
The date (DAT) and the time (CLK) for CPUs without calendar/clock function are specified as in the list.
Error at power ON or during execution
Error during program transfer from Memory Cassette
Note: Use ZEN Support Software to read the error messages for LED-type CPUs.
Error message Cause Possible solution
MEMORY ERR Program error The ladder program and the parameter settings have been cleared. Write newprogram in ZEN.
I/O BUS ERR Connection error in the I/O expansionunit
Switch off power supply and check that the expansion units are connectedcorrectly.
UNIT OVER More than 3 I/O expansion unitsconnected
Switch off power supply and reduce the number of I/O expansion units (3 or less).
I/O VRFY ERR The type of bit set in the program cannotbe used by the system
Change the wrong bit type in the program.
Error message Cause Possible solution
I/O BUS ERR Connection error in the I/O expansionunit
Switch off the power supply and check that the expansion unti is connectedcorrectly.
MEMORY ERR Program error Execute the 'All Clear' operation and rewrite the program.
I2C ERR Communication error between Memoryand RTC
Press any key and clear the error.
Error message Cause Possible solution
M/C ERR Error in the cassette program Save the error-free program on the cassette

9.1 BatteryThe ladder program and all settings are saved on the CPU EEPROM unit, but the calendar, clock, holding timer bits and the timer/counter presentvalues are held by the unit capacitor.
In the case of power supply failure, the data can be stored in the CPU for approximately 2 days (at 25 C) until they are reset.
Installation method:
1. Lean the ZEN-BAT01 battery unit over to one side and insert the clip into the space provided on the left-hand side of the CPU.
2. Connect the battery cable to the CPU connector.
3. And drag the battery clip towards the CPU.
Note: Disconnect the power supply before assembling the battery unit.
9.2 Memory CassetteMemory Cassettes can also be connected to ZEN to save ladder programs and settings and to copy these ladder programs onto other CPU units.
Installation method:
1. Remove the cover from the CPU front connector
2. Connect the ZEN-ME01 memory cassette
Note: Disconnect the power supply before mounting or removing the memory cassette.
Program Transfer
Note:
1. Program transfer includes the ladder program, parameters and all data settings. Normal and holding timers, counters and holding bits presentvalues cannot be transferred.
2. Only error-free programs can be transferred. The program will not be transferred if it contains any type of error.
3. The memory cassette allows 100,000 writes.
Menu OperationSave Transfers the CPU program to the Memory Cassette. Any
program already in the cassette will be overwritten.
Load Transfers the Memory Cassette program to the CPU. Anyprogram already in the CPU will be overwritten.
Erase Clears the program from the Memory Cassette.

9.3 Connecting the ZEN Support SoftwareThe Software can be used either for ZEN programming or for monitoring. For further information about the functions or operations, see the'ZEN-SOFT01 ZEN Support Software Operation Manual' (W386).
Node number setting
When ZEN has to be connected to the Software, the node number displayed both in the Software and the CPU must be identical. Follow the stepsbelow to set the ZEN node number.
