Blocks in the range of 5001 to 5006 are used for Port 1, and blocks in the range
of 5101 to 5106 are used for 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 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 format of
the block is displayed below:

5.2.8 Override File Map Configuration Blocks (7000 and 7100, 50
entries per port)
The Override File Mapping feature allows users to assign PCCC-type data table
memory addresses (like N10, F8, B3, etc.) to specific areas of the module's user
data memory. This allows older DF1 applications and drivers to access the
module's memory as if it were a PLC5 or SLC processor. Override File Mapping
also allows users to change the module's default PCCC-type data table
addressing by assigning specific data file numbers to specific areas of module
memory.
