■Process data
Process data is the cyclic data which is exchanged periodically between the base module and
device.
Process data consists of PD_IN (process data input); 4 BYTE and PD_OUT (process data
output); 2 BYTE as shown below.
- The process data of this product is Big-Endian type.
When the transmission method of the upper communication is Little-Endian type, the BYTE
order will be changed.
Refer to the table below for the Endian type of the major upper communication.
