４．Pressure setting method and output monitoring
Pressure can be set by sending input data from the master PLC to the regulator where the F.S
is based on a 12 BIT resolution.
Do not operate the product outside of the specifications.
<Relationship between set data and pressure>

From the 16 BIT process data (2byte), input the 12BIT resolution starting from 3rd BIT to the
14th BIT.
Refer to the communication data for further details.
