6. How to operate EX500 - GPR1 ( PROFIBUS-DP )

6 -1. Communication wiring

A twisted pair cable with shield is used in the communication wiring of PROFIBUS- DP.

A maximum length of cable depend on communication speed.

The specification of cable length is based on TYPE A cable which has parameters shown below.

・Cable specification
