Please clarify on what is happening on the following code.
This code is writing data to the MCM module of a SLC 5/02.
The data written on the MCM module is read by a yokogawa DCS.
The protocol is Modbus.
I can not understand on what is happening on the different block. What is the purpose of"EQUAL" and "COPY" instruction of each rung. Whats the use of N70:50 and the N70:100.I observe also that they have the same Destanation. It will not overide the content of M0:10:1?

I will post another code the configure the communicatio between the SLC 5/02 and the Yokogawa DCS
thanks,
