I get this PM today. I prefer to answer in the forum in case others have similar questions.
Steve,
Good morning! You seem to be the resident expert on GE PLCs here. I have a quick question that seems to come up occasionally on here and other forums.
I'm quoting a job to upgrade a Series 90-30 system to an Rx3i one. The 90-30 has 1 CPU in the "main" rack and 4 expansion racks. There's a seemingly random mix of digital/analog and input/output modules across the the racks. There are 14 total Horner Electric temperature input modules (TC and RTD). Can these modules be reused in an Rx3i system? I'm getting some mixed answers (some from Emerson vendors). At about $2K/each, purchasing 14 new Emerson temperature modules is no small cost!
The 90-30 installation is poorly documented and is on the other side of the world. Even better, no one there will touch the system out of fear of breaking something. As such, I don't know for sure what Horner modules are installed, but I believe the TC modules are HE693THM166 and the RTD modules are HE693RTD660.
Any insight you could provide would be appreciated! Thanks for your time.
Regards,
Kyle Bakis
The Horner modules should work fine. They will be "Third Party" modules in the hardware configuration. Your best bet for the conversion is to get a copy of the project file for the existing system and copy the address and parameter settings from that.
