Programming Instructions
Depending on whether the command parameter (DW n) contains the command "IW", "AW",
"EW", "N1" or "N2", either the actual value, the initial setpoint, the end setpoint, the zero shift of
channel 1 or the zero shift of channel 2 is stored in data word DW n+2 or DW n+3.
Any interrupt processing of a setpoint is indicated in data word DW n+2 (setpoint with inter-
rupt -+ assignment of bits 4 to 7 of DW n+2: 0100 = 4). The bit assignment is shown below.
