Hello Darniel; In my experience machine manufacturers will put communication cables on their "optional" list and charge you for every one... Now, you can get around this problem with a little bit of work: a PC-PPI Adapter cable can be replaced by a simpe RS-232 to RS-485 converter, there is no protocol conversion required for PPI. It may be that the pinout you are following is not adapted to the task, so your connection is faulty. Follow the guidelines proposed by Hussam in the following thread: PC/PPI cable- Wiring scheme https://support.industry.siemens.com/tf/pt/en/posts/48964/ Hope this helps, Daniel Chartier |

Thank you very much for your help, I really appreciate it! So using a RS232 to RS485 converter should work. Since I have the RS485 PCI expansion on the PC though, shouldn't I be able to use it instead of the converter (because no conversion would be necessary, RS485 PLC to RS485 PC)? |
