The processor transfers data to the module (block transfer write) and

from the module (block transfer read) using BTW and BTR

instructions in your ladder diagram program. These instructions let

the processor obtain input values and status from the module, and let

you establish the module’s mode of operation.

1. The processor transfers your configuration data to the module via

a block transfer write instruction.

2. External devices generate analog signals that are transmitted to

the module.
