•
Set according to the following table
Item
Descriptions
Station No.
Sets one of station from 0 to 31.

Communication
channel
•
RS232C null modem or RS422/485: can be selected as a communication channel when
communication is processed by built-in functions of GM7U Main unit or Cnet I/F module (G7L-
CUEC).
•
RS232C dedicated modem: can be selected when communication is processed by Cnet I/F
module (G7L-CUEC).
•
RS232C dial-up modem: can be selected when common modem communication calling the
opponent station is processed by Cnet I/F module (G7L-CUEC).
* Notes: RS232C dedicated modem and RS232C dial-up modem communication can be processed only
by
Cnet I/F module (G7L-CUEC) support RS-232C, not Cnet I/F module (G7L-CUEC) supporting RS-
422/485.
Timeout in
Master Mode
•
It’s an interval waiting after sending request frame from GM7U before receiving a response.
•
Default value is 500ms.
•
Setting must be done in consideration of maximum interval of sending and receiving cycle of a
master PLC.
•
If the time out is less than the maximum interval of the s/r cycle, error can occur.
Dedicated
Master/Slave
GM7U can read from and write on Slave GM7U.
Read status of
slave PLC
Can be select especially when you read Slave GM7U for monitoring, but not for the other
purposes, lest it may cause decreasing communication speed.
(2) Setting registration list
•
Click 'master' from 'exclusive use' in 'protocol and sending mode' then 'List' button will be activated.
Select Master
