value
7.1 Set value
Profibus → GEMÜ 1436 cPos
The set value is transmitted from the master to the GEMÜ
1436 cPos in a unit which is accurate down to a thousandth.
Excessive set values (0x11) trigger an external diagnostic error.

7.2 Actual value

Profibus → GEMÜ 1436 cPos
The actual value is transmitted from the master to the GEMÜ
1436 cPos in a unit which is accurate down to a thousandth.
Excessive actual values (0x13) trigger an external diagnostic
error.

7.3 Digital input
Profibus → GEMÜ 1436 cPos
The digital inputs are transmitted from the master to the GEMÜ
1436 cPos. There are 4 inputs available.

7.4 Valve position
Profibus ← GEMÜ 1436 cPos
The valve position is transmitted from the GEMÜ 1436 cPos to
the master in a unit which is accurate down to a thousandth.
In the NoInit state, the position corresponds to the
potentiometer range. After the initialisation (InitValve), the
position corresponds to the valve area.

GEMÜ 1436 cPos ↔ Profibus
If the same information is to be transmitted several times, the
data record must be changed via the toggle byte.

For instructions 0x45, 0x44 and 0x57, the
instruction "N" (NOP) should be sent after querying
so that the query is only processed once.
7.6.1 No action
When using the "N" (NOP) instruction, no action is carried out.
The response is another NOP instruction.
Request from the master:
0xYY 0x4E ("N")
1 byte 1 byte
Response from the GEMÜ 1436 cPos:
0xYY 0x4E ("N")
1 byte 1 byte
7.6.2 Change parameters
The "S" (SET) instruction can be used to change a parameter
in the GEMÜ 1436 cPos via the Profibus. As a response, the
GEMÜ 1436 cPos returns the SET instruction with the changed
parameter value. If the value is above the valid value range, an
external diagnostic error with code 0x21 is generated. If the
value is below the valid value range, an external diagnostic
error with code 0x20 is generated.
If the parameter does not exist, an external diagnostic error
with code 0x22 is generated and the value 0 is returned.
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.
The individual parameters for the GEMÜ 1436 cPos can be
found in chapter 9.
Request from the master:
0xYY 0x53 ("S")

Response from the GEMÜ 1436 cPos:
