Appendix 4.6 When a sequence program was used for the initial
setting
(1) Stopping operation
● If PID continuation flag (Un\G169) is set to Continue (1), control does not stop even when Setting/operation mode
instruction (Yn1) is turned off. Change PID continuation flag (Un\G169) to Stop (0) and turn off Setting/operation mode
instruction (Yn1).
Whether the control has been stopped can be checked by Setting/operation mode status (Xn1) being off.
● If a CPU continuation error (such as SP.UNIT DOWN and UNIT VERIFY ERR.) is occurring due to an error in the module
to be changed, the buffer memory data cannot be saved.
1. Open the "Device test" window.

PROM backup instruction (Yn8)
• Default setting registration instruction (Yn9)
• Setting change instruction (YnB)
3. If the buffer memory data to be saved beforehand is
not recorded, monitor the data in "Buffer memory
batch monitor" and record it.
