Got a water plant using a Modicon 9/85 265 PLC. Existing program needs to be modified. Have just the PLC, and nothing else such assoftware,etc. (Well, we do have the program printed out) I'm told from the vendors I spoke to that whatever software I use, I'm married to. Previous programmer (Deceased) used Concept, I'm told. Whatever, I will be needing to have a stab at it when the new actuator comes in. I am open to suggestions, as I have been a Koyo guy for years. (What can I say, I bid jobs with it and I get them.) I plan on having the Plant Manager buy the software as well as a laptop for the sole purpose of connecting to and making whatever changes need be as the time comes. Thanks in advance for any advice and wisdom you can impart on this ModiNoob.
