4–2 Writing Configuration to and Reading Status from Your Module with a Remote I/O Adapter

During normal operation, the processor transfers from 1 to 4 words

to the module when you program a BTW instruction to the module’s

address.

Read programming moves status and data from the frequency input

module to the processor’s data table in one I/O scan. The processor’s

user program initiates the request to transfer data from the

incremental encoder module to the processor.

The following read and write words and bit/word descriptions

describe the information written to and read from the incremental

encoder module. The module uses up to 8 words of input data and up

to 5 words of output data. Each word is composed of 16 bits.
