Explanations of PLC Setup Settings Section 7-2
The following example shows EM bank 2 converted to file memory.
Peripheral Port Settings These settings are effective only when pin 4 of the DIP switch on the front of
the CPU Unit is ON.
The default settings for the peripheral port are: host link mode, 1 start bit, 7
data bits, even parity, 2 stop bits, and a baud rate of 9,600 bps. Set the periph-
eral port settings in the PLC Setup when you need to change these settings.
Note When pin 4 of the DIP switch on the front of the CPU Unit is OFF, the CPU
Unit automatically detects the communications parameters of a connected
Programming Device (including Programming Consoles). Those automatically
detected parameters are not stored in the PLC Setup.
RS-232C Port Settings These settings are effective only when pin 5 of the DIP switch on the front of
the CPU Unit is OFF.
The default settings for the RS-232C port are: host link mode, 1 start bit, 7
data bits, even parity, 2 stop bits, and a baud rate of 9,600 bps. Set the RS-
232C port settings in the PLC Setup when you need to change these settings.
Specify the frame format when no-protocol mode is selected.
The RS-232C port settings can also be changed with STUP(237). The RS-
232C Port Settings Changing Flag (A61902) is turned ON when STUP(237) is
executed and it is turned OFF when the RS-232C port settings have been
changed.

Peripheral port communications settings when DIP
Switch pin 4 is ON:
Default settings:
Host link mode, 1 start bit, 7 data bits, even parity,
2 stop bits, and a baud rate of 9,600 bps
User-defined settings:
Set the communications mode (host link, NT Link,
or peripheral bus) and other settings such as the
baud rate.
