Change parameters
The “S“ (SET) instruction enables the change of a parameter in the cPos via the Profibus.
As a response, the cPos returns the SET instruction with the changed parameter value. If
the value is higher than the valid range, an external diagnostic error with code 0x21 is
generated; if below, the error generated has code 0x20.
Where the parameter does not exist, the diagnostic error triggered has code 0x22, and the
value returned is 0.
In case of a parameter change, the new value of the parameter is returned to the master
together with a SET instruction.
Where the parameter does not exist, the value returned is 0.

Request parameters
The “G“ (GET) instruction is used to request from the cPos the value of a parameter via
the Profibus. The cPos responds with a GET instruction containing the parameter value.
Where the parameter does not exist, an external diagnostic error with code 0x22 is triggered.

When the parameter value in the GEMÜ 1436cPos changes, it is

Attention:
 When a new error occurs, the serial numbering of the listed errors changes.
Error 0 then becomes Error 1, Error 1 becomes Error 2, etc.
 Once the error list is full, the oldest error in the list is deleted.
 If no entry on the required number is found in the error list, the response value is 0xFF 0xFF 0xFF 0xFF
 With number 0 the current error can be monitored
 If there is no error in the error list, error 0x00 0x00 0x00 0x00 is displayed

Trigger action in the cPos
The ”A“ (Action) instruction is used to trigger an action in the cPos. Depending on the action to be triggered, additional parameters may be required.
As long as an action is active, no other action may be triggered. Where this is attempted,
the cPos will ignore the new action and generate an external diagnostic error with code
0x40.

GoClose
Control function 1 moves the valve to the closed position.
Control function 2 moves the valve to the open position.
Once the valve is in the required position, this needs to be communicated to the cPos.
This then takes the position as “closed“.

Find function
This action determines the control function of the valve and the air flow of the inner pilot
valves. When control function 2 is determined, the cPos swaps the open and closed positions so that the 0% displayed corresponds to the Closed position and 100% to the Open
position.
