Hi all, I recently took over a water system running Unitronics gear, a V1210 HMI/PLC combo + I/O modules. The problem we have is that the original SI "owns" the software program and getting them to do any work is like pulling teeth, we've waited a year for simple HMI/sensor updates and there are bugs in the software. We tried using Visilogic to connect to the PLC and see if the program can be "uploaded" but seems only the binary was ever flashed so we don't have the source and they refuse to send it to us. This seems weird to me since we are happy to pay a release fee, and they obviously aren't interested in supporting us.Our options are to find a new programmer to redevelop + commission the software on existing hardware or rip and replace the hardware, upgrading at the same time. I'm leaning toward the second option as the gear is ~15 years old. Any advice on how to approach this and what gear is recommended? The Unitronics setup has been reliable except for being hacked a few years ago, the biggest gap is we want to make programming changes inhouse and have more options for analytics, exporting data etc. The Unitronics "unicloud" product is extremely poor.Appreciate any advice here.
