ControlWave I/O Expansion Rack Instruction Manual
Range: 2101-2260 (20 per board)
Example: To read the HSC timestamp register on board 7, find HSC
timestamp register in the first row of the table, below, then move down
that column until you reach the board 7 row to determine the HSC
timestamp register for that board, in this case (2233). So your Modbus
command should request register 2233.

Range: 3101-3260 (20 per board)
Example: To read the eleventh FP input on board 7, go to the Board 7
column of the table, below, to determine the range of FP inputs for that
board, in this case 3221-3240. The eleventh FP input in that range
would be 3231, so your Modbus command should request FP input
3231.
