8.3.1.10 Programming of read requests
Procedure
1. Define the user data range of the controller (define the location of the user data in
the host system).
Observe manufacturer−specific data.
2. Enter the code of the desired parameter into the "code" field (output data).
3. Job identification / service = read request
4. Check whether index and subindex correspond with the job and whether the job
identification is
Ø 0:
– If the criteria are fulfilled, the desired controller data from the field "Parameter
value" are transmitted to the master.
– If these criteria are not fulfilled, the response identifier is negative (high nibble of
byte 1 = 7
hex
). In this case, the error information can be read out from the entry in
the low word.
Example:
The heatsink temperature (43 °C) of the controller is to be read (C0061).
ƒ Job identification (high nibble in byte 1)
– Read simple parameter: "1"
ƒ Code: (low nibble in byte 1 and byte 2)
– C0061: 61 = 3D
hex
ƒ Lenze subcode (byte 3):
– Subindex = 0, as there is not subindex under code C0061.
ƒ Bytes 5 ... 8: Data (not contained in the request telegram)
– Data 1 ... 4 = 43
° C x 10000 = 430000 = 00068FB0
hex
Result:
ƒ Request telegram from master to drive:
