37.16 RAS Functions
*1 If a safety communications error (minor error) occurs between safety stations, a safety station interlock will be triggered for safety
communications between relevant stations, and safety communications will not be resumed until the safety station interlock is released.
The safety station interlock is released with safety special register areas (safety station interlock release request for each safety
connection). ( Page 885 List of Safety Special Register Areas)
For details on the safety station interlock status, refer to the following.

How to clear errors
Errors in the SIL2 Process CPU can be cleared in the same way as for the standard CPU. ( Page 135 How to clear errors)
The following describes how to clear errors in the SIL2 function module. The errors in the other system cannot be cleared.
Clear the errors separately in each system.
■Using the engineering tool
Clear errors with the module diagnostics function of GX Works3. ( GX Works3 Operating Manual)
■Using the buffer memory
Clear errors using operations of buffer memory.
1. Check the standard program and identify the detected continuation error using Un\G0 (Latest self-diagnostic error code).
2. Eliminate the cause of the detected continuation error.
3. Set 1 in Un\G50 (Error clear) in the standard program to clear the error.
*1
*1 After the error is cleared, 0 is automatically set in Un\G50 by the system.
