Hi folks, Was looking for some guidance. I've set up a test rig with a 315 CPU connected to a IM153 with various I/O. I want to detect wire break on one of the analog input modules which I can get to work no problem using SFC59 and OB82. My issue is this..... In the hardware config the module start address is 608 for first channel. So i used this figure in OB82 (when failed module equals 608 set a flag). In my FC containing SFC59 at LADDR I used the syntax W#16#608. Everything works fine. However.... I have now used the same code on a 414 CPU connected to many items but I can no longer detect wirebreak. When i changed the syntax from W#16#608 to W#16#260 (the hex value) everything started to work?? Could somebody please help? Should i be using the 608 value (the number in HW config) or the hex value in my FC and the OB? Have attached the code (OB82, SFC59 and Hardware Config) Much appreciate any help.
