  1. I am having a similar issue. Using Prosoft Modbus Ethernet card for compactlogix and Gardner Denver AirSmart Controller Comm module. I can ping the comm module, but I get a error code -48 when I try to read from the module. It is the same error as if it was not connected at all. I have tried different cables, and bypassing the ethernet switch. What else do we have to do with the AirSmart comm module other than enter the IP address, subnet mask and gateway.
