After making some changes I needed to put the program back into to do some testing with the existing Micrologix 1200 and ran into some problems during the changes and testing.ġ. It went very smooth but it erased my expansion module including their configuration and set my input filters on inputs 0 and 1 back to their defaults so the HSC function file would not count. The analog inputs are only 0 to 10 VDC and you canÆt configure the data format like you can with the 1762-IF2OF2.Īt this point I converted the Micrologix 1200 program to a Micrologix 1100.
Lucky for me, I had exactly 4 expansion modules.ģ. I had some other questions for Rockwell and tech support did inform me of this when I was talking to them. BIG WARNING û The Micrologix 1100 only supports 4 expansion modules compared with the Micrologix 1200s 6 expansion modules. In the end I only had the encoder on inputs 1 and 2 and used five of the base outputs.Ģ. Most of the Outputs went through the expansion modules and I had enough spare inputs on the IQ16s to move all of the inputs to the expansion module. There is only 10 inputs and 6 outputs on the Micrologix 1100 compared to the Micrologix 1200s 24 inputs and 16 outputs. I/O û There are some things you need to watch out for when planning to upgrade to a Micrologix 1100 or designing a new project for that matterġ. So not only did this test the capabilities of the Micrologix 1100 but also how easily it could be swapped for a Micrologix 1200. All other program changes would have to be made in 2 minute openings when new parts were being loaded. This was a much cheaper solution but the machine could only be down twice for a half a day each time. I probably could have used a memory module and some 1761-NET-ENIs to do it but it seemed like a perfect time to try the Micrologix 1100. It was also to be hooked to the Ethernet network for data acquisition. I was asked to make some upgrades to it that was going to push the data memory over the Micrologix 1200s 2k limit. It uses a Panelview 600 DF1, 2711-T6C16, as a HMI. It uses one high speed counter (Input 0 and 1) hooked to an encoder and uses the 1762-IF2OF2 to control a AB 2098-DSD-020 servo drive. I built the controls for the machine about 4 years ago using a Micrologix 1200. I have finally got an application to use one on and I thought I would share my first impressions with you.įirst here is a little background on the machine.
I know there have been several of us contemplating whether or not to use the Micrologix 1100.
