Posted 25 Apr 2016 I've been using CX-Programmer since I got started in the automation industry a few years ago; so while I'm no expert with CX I can usually figure out a way around the road blocks I hit. Sysmac is a whole new beast for me. I really don't like IEC style programming; I like addresses- though that is probably just from a lack of experience. I've only had a bit of training (read: one day) with TIA Portal; and I've written a few programs with Proface's GP-ProEX. I now have a customer that is using an NJ plc on a machine in place of a CJ2 that was on the first one we built. So I'm in the process of basically rewriting the whole program in Sysmac; but I'm used to using a lot of quick and dirty functions that I can no longer use. For example I'm used to being able to use the bits of a word as Boolean outputs; and have those bits modify the value of the word to accomplish something else. Here is a quick example: W100.00 (Fault 1) Energizes. IF W100>0 THEN: Energize W200.00 (Fault Exists) Hope that makes sense. Basically if a bit within W100 comes on then there is a fault and I can use the value of W100 being greater than 0 to energize the primary fault coil. That allows me to have a bit by the individual fault to activate a message on the touch screen; but it also allows me to activate the main fault coil without having to put everyone of the bits in a huge parallel branch. I know I could just use an INT tag and write a number to it for each fault; but I still need an individual address to trigger the alarm message on the NS screen. Is there a way to accomplish this without having to write a bit and a move statement for each fault? 1 person likes this Share this post Link to post Share on other sites
Posted 25 Apr 2016 Well, I guess I should have read some of the posts that I opened in another tab before I submitted my question. It appears I need to use a union. Share this post Link to post Share on other sites

Yes. You can accomplish exactly what you want using a union. Share this post Link to post Share on other sites
