Hello I have an SLC5/05 configured to communicate to a Proface HMI via RS232C. I have Ethernet connected to a DCS system. Ethernet to DCS is working fine, however, serial comms is my problem now. I am getting the following error "RHAA130: PLC1: Error has been responded for device read command. STS Response [10H], EXT Response [00H]. Checked internet and cannot locate the error code. Please provide some assistance. Bobby Tongga
