6.4.6 EXPANSION SERIAL SETUP
This section describes the communication setup for a device connected to the
Expansion Serial Interface. This setup screen will not display unless the communi-
cation protocol for the Expansion Serial Interface (specified with
SET UP EXPAN-
SION SIO
of the
GLC
screen creation software package) is transferred to the GLC.
If you have selected "YES" for the [SERIAL I/F CHANGE] on the [COM-
MUNICATION PORT SETUP] screen, or "Yes" for the [Serial I/F Switch]

[Project] menu, enter all of the settings related to device communica-
tion using the Extended SIO Script Protocol here, [EXPANSION SERIAL
COMMUNICATION SETUP] screen.
COMMUNICATION RATE
The
COMMUNICATION RATE
(baud rate) is the data communication speed,
measured in bits per second (bps), between the GLC and the device connected to
the Expansion Serial Interface.
The supported communication rates vary depending on the connected device.
Refer to the instruction manual of the connected device for more information. The
initial setting varies depending on the communication protocol for the Expansion
Serial Interface being transferred.
DATA LENGTH
Set the DATA LENGTH to 7-bit or 8-bit data.
STOP BIT
Set the STOP BIT to either 1- or 2-bit.
PARITY
Use this setting to specify whether an
ODD
or
EVEN
number parity check, or none
at all (
OFF
), will take place during communication.
