Hello everybody!

My name is Bernd and I have the following problem. We got for ourselves a cnc managing program from Cimco (DNCmax). The 840C is connected via a MOXA serial port. Download of NC programs works. When we try to upload, the controller always aborts it and brings the error message “check interface parameter”. Who could help me to adjust the Siemens 840C?

Hi people

I solved the problem. I replaced the Moxa with another port server and another cable configuration. This port server has another V24 chip. It worked straightaway. I worked 15 hours for nothing. The 840C from Siemens isn’t very tolerant to V24.
