![]() ![]() The only thing that changes is the digits. How do I get the command string "L1S"+temperature value, example 27C, so the command would be "L1S27" into the data type array of SINT. ![]() My problem is, the Prosoft device data table in the Logix is data type SINT. I'm using a Prosoft Technology PLX31 Ethernet to ASCII. The old PLC5 took the command string to change the temperature and did a AWA command and out port 0 the new temp setting went. The company will not update this ancient chamber environmental control. I'm working on a PLC5 to Control Logix conversion. Well, I've slept and drank a whole hell of a lot in 30yrs so I really don't care now but I need to do it again. OK that said, 30yrs ago I cared about things like PLC5 serial communications sending ASCII characters as it was a common thing. First, I'm not new to PLC programming and design.
