I currently have 4 7EA units that use chromalox heaters. All these units have an interface with a very old KOYO PLC. I am having difficulties login in to the PLC and was hoping anyone would have some knowledge on the subject of interfacing with the PLC and looking at that code. I've engaged with Chromalox company but their response has been very underwhelming and slow.
