5.4.1 SET UP SIO

This menu runs the settings related to PLC communication. Be sure to match the
settings listed below with the SIO setup on the PLC host.
COMMUNICATION RATE
The COMMUNICATION RATE (baud rate) is the data communication speed,
measured in bits per second (bps), between the GP and PLC. Match the COM-
MUNICATION RATE values in both the PLC and GP. Depending on the rate
selected, certain PLCs may not be able to be used.
DATA LENGTH
For data communications, the DATA LENGTH must be set up as 7-bit or 8-bit
data, and set up also the STOP BIT as either a 1-bit or 2-bit value.
PARITY
Set up whether no parity check, or an odd or even number parity check will take
place during communication.
CONTROL
Data flow CONTROL prevents the overflow of data sent back and forth. Select
either X-CNTRL or ER-CONTRL.
COMMUNICATION INTERFACE
Select one of the following options for the communication format: RS-232C, RS-
422 (4 line), or RS-422 (2 line).
When using an RS422 cable and the Memory Link format, be sure to
select the 4-line option.
