15pcs of Micro830 - unused NEW
PLC_research posted a topic in For Sale, Employment, Services or Wanted
Dear all, I've got 15 pieces of Allen-Bradley Micro830 2080-LC30-48QWB (RS part no. 750-8621) pulled from new machines as we had to replace them by Siemens PLC's (customer request). In short: these PLC's are brand new and have only been programmed once, but the original packaging material isn't there anymore. If you are interested, please let me know. FYI; our company is located in The Netherlands. Best regards, Sander -
I have a fairly new Allen Bradley PLC 2080-LC50-48AWB. I am making a list of all of our on-site PLC's that have batteries, in need of periodic replacement. Can anyone tell me if Allen Bradley 2080-LC50-48AWB PLC has an onboard battery that needs periodic maintenance. I have been searching the manuals all morning, and find no reference to any installed battery. The manual however cautions if the unit has a battery, be sure to handle safely. If it has no battery, what is the best method to ensure program does not get lost, due to extended outage? Thank you for your response.

Micro850-I/O tags reading zero/not updating
Arceus posted a topic in Allen Bradley / Rockwell Automation
Hello, I have a Micro850 PLC that has 5 2080-IF4 plug-in modules attached. Each of these modules are programmed to read 4-20 mA output signals from various sensors. It also has interlock switches connected to embedded digital input ports. When I download the program to the PLC from CCW, the message prompt that enables 'Remote Run' does not appear. I can't seem to switch the controller to run mode. Moreover, while connected, the I/O tags all read 0. I have tested the sensor wire leads with multimeter and they do give out output signals in the range of 4-20mA. Not sure why CCW is unable to read. The DI status LEDs also light up when I turn on the switches. I assumed that it might have to do something with the firmware, so I reset the firmware to default, that didn't help either. Any ideas on what the issue is or how to fix the issue? Thanks.
