Process Data IN
When the solenoid valve is operating in the overactive state, the "Warning" flag of the Process Data IN
changes to "1: ON" and the code corresponding to the error code is displayed, besides updating the
values of the above parameters.
An IO-Link event code is stored in the Detailed Devices Status (Index:0x0025) of the parameter.

Event code
Error description
Control processing
(Solenoid valve operation)
E 10
0x8D10
The air supply-side solenoid valve is
in the overactive state.
The pressure control does not stop.
E 11
0x8D11
The exhaust-side solenoid valve is
in the overactive state.
The pressure control does not stop.
* The EVD continues to controlled pressure even if it is determined to be in the overactive state.
How to obtain data
Data on solenoid valve’s overactive state can be obtained by reading the index described in "Acquired
data".
Ex: Monitoring of the overactive state of the air supply-side solenoid valve
Checking operating time in overactive state
Read Index: 0x0401.
When a data value of 3 is returned -> The operating time in the overactive state is 3 hours.
Checking the number of operations in overactive state
Read Index: 0x0402.
When the data value 10 is returned -> The number of the operations in the overactive state is 10.
