yes, bothare you concerned about the source of the value of n7:50 in general or the specific instance of the value of n7:50 equal to 15?
Looking at the Allen Bradley Data Table Access Module User Manual, on Page 49, it says (if the jumper on the DTAM is in the default "Modify" mode), then:The project picture posted here is for a palletizer. The palletizer gets it's stack and pattern commands loaded from a DTAM unit. I can not find any reference to this integer in the Dtam's.
That means that an operator could first select an address in the connected PLC, such as N7:50, then enter any valid number into that address, say Pattern Numbers 1 to 99 for example. It seems likely that the DTAM is or was at one time used to change the value of N7:50.You may also use the numeric keys to enter or change a value at a displayed address.
Hi folks,
If I get him right, he is wondering why is the OTE B3:13/7 is ON while in the data table the value of N7:50 equals to 1, while the logic is saying the OTE should only be set if N7:50 equals to 15

I agree, the PLC data may not reflect current values. But being offline will not change the source of the value in N7:50. Wherever that number comes from, it will still come from the same place once the program is restarted. I think the value of N7:50 is being set (or can be set) by the external DTAM module Modify function.Since he is currently OFFLINE in the project, I wouldn't trust all current bit status and data table files to reflect the logic accurately.
