Q: I have a CPM2A plc and a NT11 pt.I have read in the NT11 instruction manual that when numerical data is input at the NT11, this is automatically notified to the PT status notify area allocated in the PLC memory as follows.
I set the notify area to DM800, and it says that there is a numeral setting strobe flag which is turned on when a data upgrade occurs (when the enter button is pressed).Now my problem is that that I dont understand that where is that numeral setting strobe flag, and how can I check it in the plc ladder diagram?In the instruction manual there is a simple ladder diagram for this problem ( I have attached this page), but in this diagram the flag`s address is 11211, but I didnt find this address.
So my answer is that how can I detect in the plc ladder diagram that when after a numeral input I press the ENTER button on the NT11???

Please help

A: The NT11S Control/Notify area would be better placed in a different memory area.
The DM area in the CPM series is not a "bit" area.
The Numeral setting strobe flag is in word m+2 bit11.
Example: if the Notify area is set for H10, the Numeral setting strobe flag
would be bit H12.11
