Set the serial port settings in the PLC Setup when you need to change these settings from the
defaults. Specify the frame format when no-protocol mode is selected.
The port settings can also be changed with STUP(237). The Serial Port Settings Changing Flag
(A619.02) is turned ON when STUP(237) is executed and it is turned OFF when the port settings
have been changed.
When pin 5 of the DIP switch on the front of the CPU Unit is ON, the CPU Unit automatically detects
the communications parameters of a Programming Device (including a Programming Console) con-
nected to the RS-232C port. Those automatically detected parameters are not stored in the PLC
Setup.
