2-18 Module Operation
OP MODE: Operating Mode Bits
The module uses these two bits to tell the processor what mode it is
in. In class 1, the data value that an input word contains changes
based on the operating mode.
Table 2.2 Mode Bit Settings
Output State Byte
These bits correspond to the real or virtual state of the outputs. Bits 00
through 03 represent real outputs. Bits 04 through 07 represent virtual
outputs.
Counter Status Bytes
Each counter has an associated status byte. The format of the byte
depends on the module’s class of operation as shown below.
