7.1 How to Change the Operation Mode (System Register
Setting)

7.1.1 Operation Mode Changeable

Remote I/O control when an error occurs
The operation mode when a transmission cable disconnected or a slave station does not work correctly
can be set;
- whether to continue or halt the operation.
- whether to check the occurrence of error with the LEDs.
Confirmation for connection of slave station
When a remote I/O map is registered, you can start remote I/O control only after all of the slave stations
which have been registered in the CPU are turned on.
Reference: For information on registering a remote I/O map, <Chapter 6 Remote I/O Map>
Remote I/O update timing
You can choose whether remote I/Os will be simultaneously updated with the normal I/Os or not.
When a large number of I/O points are controlled, it will be a considerable amount of scan time for
processing remote I/O. In this case, when you select "Scan tiem asynchronous mode", the normal I/O
scan time can be shorter.

7.1.2 How to Change the Remote I/O Operation Mode

By setting the system registers of the CPU, you can change the remote I/O operation mode.
To set the system registers, use a programming tool.
When using the FP programmer: execute "OP-50".
When using teh FPWIN GR: Set [Action on Error] and [Remote I/O setting] under [PLC Configuration].
* For the details of the operation mode setting procedure, refer to the FP programmer or the Tool
software FPWIN GR.
Note: Precaution when changing the operation mode
To set the operation mode, the mode selector switch of CPU must be set to PROG. mode.
