Disabling duplicate address tag modules

Jesse j Kilde 3 years ago in IQANdesign • updated by Gustav Widén (System support) 3 years ago • 1

We tested this in the shop before combining programs with duplicate address tags. see the images below. there are never two of any address in the program being looked for at one time. this worked good for a half a day during testing and now we are seeing issues with the duplicate addresses loosing contact but not giving a duplicate error as you would see with two of one addressed module. the machine will work for a while and then loose contact for a few seconds and come back on line. Is this a program issue because of duplicate addresses or something else i am missing?

This system design should give the project check error:

Ambiguous module address
Two or more modules on the same bus have identical address. Each module has to have a unique address.

But there is a gap in the IQANdesign project check, if you use a channel to disable modules this will trick the project check into thinking it is an ok system. I can see how one would believe the system is OK when the project check does not give an error. The project check will be updated to avoid this.
