7.6.3 Request parameters
The "G" (GET) instruction can be used to request the value of
a parameter from the GEMÜ 1436 cPos via the Profibus. The
GEMÜ 1436 cPos responds with a GET instruction containing
the parameter value.
If the parameter does not exist, an external diagnostic error
with code 0x22 is triggered.
If the parameter value in the GEMÜ 1436 cPos
changes, this is sent to the Profibus master
immediately. It is not necessary to continuously
request the parameter.
Request from the master:
0xYY 0x47 ("G")
1 byte 1 byte
Response from the GEMÜ 1436 cPos:
0xYY 0x47 ("G")
1 byte 1 byte
7.6.4 Read error list
The error list can be requested using the "E" (Error List)
instruction.
‫ ܟ‬When a new error occurs, the serial numbering
of the listed errors changes. Error 0 then
becomes error 1, error 1 becomes error 2, etc.
‫ ܟ‬Once the error list is full, the oldest error in the
list is deleted.
‫ ܟ‬If no entry on the required number is found in
the error list, an external diagnostic error with
code 0x34 is triggered. In this case, the return
value is 0xFF 0xFF 0xFF 0xFF.
‫ ܟ‬The current error can be monitored with number
0.
‫ ܟ‬If there is no error in the error list, error 0x00
0x00 0x00 0x00 is reported.
Request from the master:
0xYY 0x45 ("E")
1 byte 1 byte
Response from the GEMÜ 1436 cPos:
0xYY 0x45 ("E")
1 byte 1 byte
7.6.5 Amount of active errors and readout of the active
error
The "D" instruction can be used to request the number of active
errors and the active warning selected via the ID.
Request from the master:
0xYY 0x44 ("D")
1 byte 1 byte
The first error is requested with number 0x00 0x01.
Response from the GEMÜ 1436 cPos:
0xYY 0x44 ("D") Number
of active
error
1 byte 1 byte 2 bytes
ID 0x00 0x00 0x00 0x00
2 bytes 4 bytes

Example:
The GEMÜ 1436 cPos potentiometer is moving in the wrong
direction, i.e. error "020: Pot Wrong Dir" is active.
Request from the master:
0x00 0x44
Response from the GEMÜ 1436 cPos:
0x00 0x44
7.6.6 Amount of active warnings and readout of the ac-
tive warning
The "W" instruction can be used to request the number of
active warnings and the active warning selected via the ID.
The first warning is requested with number 0x00 0x01.
Request from the master:
0xYY 0x57 ("W")
1 byte 1 byte
Response from the GEMÜ 1436 cPos:
0xYY 0x57 ("W") Number
of active
warning
1 byte 1 byte 2 bytes
Example:
A compressed air failure was discovered, i.e. error "030: Air
Missing" is active.
Request from the master:
0x00 0x57
Response from the GEMÜ 1436 cPos:
0x00 0x57
