Hello, I have a PG740 (6ES7740-1AA00-YA0), I can not to connect this to the PM16 on the Simadyn D PLC (6dd1600-0AF0---PM16), I´m thinking the problem is the incorrect communication cable that I´m using, please could you send me the pinout?, I am going to make new cable, the conector on PLC is DB25, and the Com1 on PG740 is DB25 too.
Thank You
Best Regards
Dear Customer,
You are correct; an incorrect communication cable can cause connection issues between the PG740 and the Simadyn D PLC (PM16). Here's the pinout information for a serial connection using DB25 connectors on both sides. This configuration utilizes a null-modem cable.
Important Note: This pinout assumes a standard null-modem configuration. Double-check the Simadyn D PLC documentation for any specific requirements or deviations.
For more detailed information and troubleshooting, please refer to the following resources on SiePortal:
