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.

Monitoring of output pressure
The output pressure can be monitored by the PLC receiving the output data from the regulator
where the output pressure is 13-Bit. (The upper 3 Bit (29th to 31th) are 0).

Check the values from the 16th to 28th Bit of the 32-Bit (4-BYTE) process data.
(When F_1=0%F.S. and F_2=100%F.S.)
(Ex.) When the output pressure is 100%, the set pressure value is 0x0FFF.
