DerekGodown Posted April 4, 2018 Report Share Posted April 4, 2018 Hello all, I'm currently working on a monitoring system for the water tank in my industrial park. This will consist of multiple analog inputs, for which we are using an EX-RC1 and an ATC8 that we pulled out of an old project weeks before. This is my first ever project on Unilogic, and I didn't even as much as open the software until this project came to me. So I'm learning both CANbus and Unilogic from scratch. And though it is incredibly easy to use, there are quite a few things that differ from Visilogic which is my only experience in ladder logic to begin with. To learn what I needed to, I watched the webinar videos enough times to basically memorize each presenter's speech patterns. I've gotten decently far by that method as well as example projects/help menu in Visilogic, but now I'm stuck. I know I have plenty of work ahead of me from this point, but I would really like to achieve a communication so I can go from there. Our PLC is a Unistream 5 RA28 with a CX module(resistors on both ends). To test the data communication I'm using a Type-K thermocouple(jumpers are set to B.) My input is recognized on the ATC8, the RUN light is lit, as well as PWR and IO COMM on the RC1, however the BUS COMM light is blinking, from what I understand that means Im having an issue connecting to my PLC, when I check the status, it shows an 8 or a 9, telling me the FIFO is full. I used the example program in the help folders as my outline for this, but wasn't clear on what I did or did not need, so I did my best. I've been tinkering with the code running off of Trial and Error all day so there may be something small I didn't switch back to its original state or match up accordingly. it's been quite the rollercoaster. I attached my code for the visilogic RC1 portion of it, though I'm not certain if my problem lies there or in my Unilogic. As of right now I don't believe I need much of my OUT subroutine logic, its just there for future reference. If anybody has the time and understands the fine inner workings of CanBUS and can locate my error(s) I would very much appreciate the help. It's been quite the journey with this project, I've laughed, I've cried, I've cried while laughing, but now I'm ready to stop playing detective and find out how to move on from here.
