I work for an OEM and have used AB and GE for several years. This is my first experience with OMRON and things are going OK except for a couple of things. First of all, on the NT31C screen, I have created an alarm list. The alarm messages are working just fine. When the particular bit in the PLC comes on, the message shows on the screen. The major problem is that I have set all of them as an alarm and checked the "switch screen" box but the screen is not switching when the alarm goes off! What could I be doing wrong? These screens must switch automatically. That is what we usually do and that is what the customer wants so the operator will see the alarm no matter what screen is being displayed curretnly. As a last resort would I just use the Control/Notify addresses to do this on my own? I would really like to get the alarm list working properly though.
The second thing I will run into is needing to be able to "move" a number into a counter to change it's current value. In AB you would just move a constant into the counters accumulated address. Like MOV 7 t4:7.acc . I need to do this for the way we program machines. The counter steps through the sequence of operations and I need to "back up" a couple of steps if an operation does not get completed correctly and try part of it again and re-check. So if the counter has counted up to 7 say, I need to create a rung that will force a 5 back into the current counter value and be ready to keep counting from 5 again.
I appreciate any help I can get. The customer came in for the first runoff and these machines must be done by the end of this week!
Thank You
