- Restoring the factory settings when the rotary switch function is disabled by
using function removal (for F3SP66/67/71/76)
The Press & Hold operation cannot be used to restore the factory settings when the
rotary switch function is disabled by using function removal.
TIf this situation happens, follow the instructions given below.
T
Set the rotary switch (MODE switch) to C, install a sequence CPU module in the 5th or
higher slot, and turn on the power. After making sure the RDY lamp comes on, turn off
the power. This restores the factory settings.
T
Executing the above-mentioned procedure without setting the rotary switch (MODE
switch) to C clears information other than the project and CPU properties information
stored in the internal ROM.
