And fisrt of all is very slow i click in one button and after 2 3 seconds the t7a respond.

And some times when i press one button or normaly when i dont touch in the hmi give the error. Controller1: Comm Erros Stn2..

I use the driver s7 mpi direct 18.7kbps with 8 bits and 1 stop bit with even parity.

hello,

I can´t do this i comunicate with rs485 and i have 2 rs232 port´s and only one rs232 to rs485 converter.


I think that is possible put my rs485 in the midle of comunication and only spy.

is my first time with beijer and i don´t have lucky i have 11 warnings of controller1.dataitem1 and dataitem81 to 90, and i delete like the post.

If you can not spy on the communication, then the only other thing you can do is verify that all your serial port settings and cable wiring is correct. The controller help file details the cable wiring, and in iX Dev under System, you can select the serial port protocol.
