Note
- If you want to reset the contacts of an output module in the event of a major or
moderate sequence CPU module failure, do the following: Use an output module
with 32 or less points and set the Output When Stopped field under "Input/Output
Setup" of the Configuration to "RESET". (For F3SP22/28/38/53/58/59/66/67/71/76
modules, F3YD64-1F, F3YD64-1P, F3YD64-1R, F3WD64-
□
F and F3WD64-
□
P
modules can also be used.)
- If you want to hold the contacts of an output module in the case of a major or
moderate sequence CPU module failure, set the Output When Stopped field under
"Input/Output Setup" of the Configuration to "HOLD". The behavior is independent
of the type of CPU module or output module.
