Blocks in the range of 5001 to 5006 are used for Modbus Port 1, and blocks in
the range of 5101 to 5106 are used for Modbus Port 2. The last digit in the block
code defines the number of commands to process in the block. For example, a
block code of 5003 contains 3 command indexes for Modbus Port 1. The
Command index parameters in the block have a range of 0 to 99 and correspond
to the Master command list entries.
The module responds to a Command Control block with a block containing the
number of commands added to the command queue for the port. The following
table describes the format for this block.
