Example 4: Command 7, Typed Write
In the example below, the module is writing 100 words from the local N7
file to the file address N10:10 in the PLC at node address 7. The variable
N7BASE% is defined in the rack configuration.

Example 5: Command 5, Read-Modify-Write
In the example below, the module writes to three addresses in a PLC,
N7:0, N7:2, and N7:4. The AND/OR mask pairs are stored in three
consecutive pairs of registers starting at B3BASE%. The variable
B3BASE% is defined in the rack configuration.
