The code will appear as displayed in Figure 47.3. Notice in the row with register 40000 the results cell has 1110
1010, which represents the first eight coil states. The least significant bit is coil 0, so Pulse 1 Power Compara-
tor Enable is Off “0b0”. The next row has the next eight coil states and starts with register 40008 which is coil
8 Comparator Action after Pulse 1 and it is also Off “0b0”. The next row starts with register 40016, coil 16, or
Alarm – Trigger Enable.
Discrete inputs are accomplished in the same manner as described for coils; however, you must change the
Function Code to 2.
