Programming Devices: Programming device pg740

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

PG740 and Simadyn D PLC (PM16) Communication Cable Pinout

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.

Pinout (DB25 to DB25 - Null Modem)

  • PG740 (COM1)     PM16 (DB25)
  • Pin 2 (TxD)          Pin 3 (RxD)
  • Pin 3 (RxD)          Pin 2 (TxD)
  • Pin 5 (GND)          Pin 7 (GND)
  • Pin 7 (RTS)          Pin 8 (CTS)
  • Pin 8 (CTS)          Pin 5 (RTS)
  • Pin 4 (DTR)          Pin 6 (DSR)
  • Pin 6 (DSR)          Pin 4 (DTR)

Important Note: This pinout assumes a standard null-modem configuration. Double-check the Simadyn D PLC documentation for any specific requirements or deviations.
