8.5.5.2  1:1 Communication with Programmable Displays of GT Series 
For a 1:1 MEWTOCOL-COM connection between the FPΣ and a programmable display of the 
GT Series, an RS232C cable is needed. Communication is performed via commands from the 
programmable display and responses from the PLC. 
No program is required for communication. Simply set the mutual communication settings to 
operate the PLC via the programmable display. 
It is recommended to connect the computer to the TOOL port of the FPΣ. A connection cable 
(order no. AFC8513D) with a 5-pin mini-DIN connector and a 9-pin Sub-D connector is 
available.
