OK, Go retrieve this one and try it. Use PLC22 to talk to your device. See the Comment in the Client Network. You must use Un-Optimized DB as the Variant. https://tsuoad.box.com/s/bfb5kphv7a0et2xo9ekm |

Dear GRAD, thank you for your time. It does not work, I get no data. I have tried changing the address to 40002, it still does not work. I tried disconnecting PAC3200 from switch. It shows no error. If I go to communicate with the PAC directly it works, but trough this MODBUS_CLIENT it does not work. Could you explain what un-optimized DB means? I looked at my project DB, and it is also not optimized. Could you explain MB_DATA_LEN 10, and array of integers for a DB?
