8–6 Using the RS1 Module with a Programmable Controller
Parameter Write - when it's time to perform a parameter write B3:0.4 and B3:1.4 will be set. Data from N7:51 will written out Channel 0
to the 160 - RS1 module at location N10:30 (parameter 30). To write to a different parameter, change word 5 of the control word (N7:41)
to the new parameter number.

Parameter Read - when it's time to perform a parameter read B3:0.5 and B3:1.5 will be set. Data from the RS1 module
N10:30 (parameter 30) will be read through Channel 0 back to the controller and placed in N7:52 . To read a different parameter,
change word 5 of the control word (N7:49) to the new parameter number.
