Mode 3. Displays a 4-character message when the IODP (189) instruction is executed in the
unit’s program.
5.
Check the Automatically Transfer User Program setting to automatically transfer the user
program from one of the PLCs memory cards when the PLC starts-up.
6.
Check the Display modes at startup setting to display all selected modes on startup.
Error Log
The Error Log tab permits certain settings to be applied to error logging. Either Data Memory (DM) or
Extended Memory (EM) areas can be selected to hold the PLC’s Error Log. Refer to Chapter 6 - PLC Error
Component for a description of the Error Log. Use the following procedure to apply settings in the Error Log
tab.
1, 2, 3… 1. Check the Enable Error Log setting to enable error logging. If this is not selected, the
default log auxiliary memory is assigned.
2. Enter the Start Address setting for the error log. This is only enabled if the Enable Error
Log setting has been selected.
3. Enter the EM Bank Number setting if the Error Log is to be stored on an installed
Extended Memory Card. The Start Address setting needs to be set to the relevant area of
EM. This is only enabled if the Enable Error Log setting has been selected.
4. Enter the Number of Records setting for the number of records to be held in the PLC Error
component.
Note:
An Error Log in the Auxiliary Area (words A100-A199 for CV1000) can contain up
to 20 error records. To increase the size of the log (to 2047 records), move it to
either the DM or EM areas.
Execution Controls
Instructions can be executed and peripheral servicing performed by either using:
♦
Event driven (asynchronous) processing mode. The peripheral servicing process interrupts the execution
process cycle by sending IO refresh requests.
or
♦
Synchronised processing mode. The execution and peripheral servicing processes wait for each other to
complete the task in hand.
Consult the PLC operational manual for details when defining the execution controls. Use the following
procedure to apply settings in the
Execution Controls tab.
1, 2, 3…
1. An operand can be indirectly addressed via the DM area in either Binary or BCD. Select
the Binary setting or the BCD setting as required.
2. Set the Step Timer setting for the SFC step instructions. The default is 0.1s.
Note: For CV1000, CV2000 and CVM1/CPU21-EV2 PLCs, EM can be used for indirect
addressing of an operand.
Note:
The Step Timer setting is not available to CVM1 PLCs.
Execution Controls 1
Use the following procedure to apply settings.
1, 2, 3… 1. Check the Measure CPU-Bus Unit Cycle setting for the CPU to measure the service cycle.
2. Check the Detect Low Battery setting to flag PLC and Memory Card low battery.
3. Check the CPU standby on initialisation of bus units setting to ensure the CPU remains in
standby until SYSMAC BUS/2 terminators are detected. If this is not checked, PLC
operation begins regardless of the presence of terminators.
4. Check the Error on power off interrupts setting to ignore a momentary power interruption
(and not generate an error) or leave unchecked to generate an error on power off.
Execution Controls 2
Check the following settings as required.
♦
The Duplication action error setting.
