•The process data of this product is Big-Endian type.
When the transmission method of the upper communication is Little-Endian, the byte order will be changed.
Refer to the table below for the Endian type of the major upper communication.
Endian type Upper communication protocol
Big-Endian type Such as PROFIBUS and PROFINET
Little-Endian type Such as EtherNET/IP, EtherCAT and CC-Link IE Field.

Diagnostic information
This product can detect the device error by diagnostic bit in the process data.
Monitoring items of the device condition can be set by the diagnostic information selection [F_0].
Set value Content
ALL
All errors
Diagnostic bit will be "1: ON" when either of the following errors is generated.
•Product internal failure
•Residual pressure error
•Exceeding upper limit of the temperature in the product
•Out of the rated pressure (when HHH and LLL are generated.)
PrES
Pressurizing error
Diagnostic bit will be "1: ON" when the following error is generated.
•Out of the rated pressure (when HHH and LLL are generated.)
oFF
Unused
Disgnostic information is not used.
