Dear Sirs, I have used anapplication exampleto start a communication between 1xPAC3200 and S7-1200. I have all the same equipement, but only PLC is different. It isS7-1200 CPU1212C AC/DC/RLY. After compiling program, I wanted to try my PAC. I used my adress of 40002 ( Va-n voltage) since i have no other measured size. Unfortunately I do not get any reading from the buffer. It is 0. If I disconect the pac from SWICH MODULE CSM1277, I get error so basically comunication exists. What could be the problem of not reading my data on MB_CLIENT. Best regards,

The address for 40002 in the PAC should simply be 2 when reading regular Modbus registers. perhaps a screenshot of your block configuration may help. |

Yes, has been for a while now. You have either a Client or Server Block. The Client takes alittle more work of course but works well. |
