6.3.2 Parameter communication with the controller
Read job
1. Determine the user data of the controller: i. e. determine the location of the DP user data in
the host.
2. Enter the address of the desired parameter in the field ”Index and subindex“ (DP output
data).
3. Job/service = Read job and the bit “job/handshake“ must be changed (DP output data).
4. Check, whether the bit “job/handshake“ is the same for the DP input data and the DP output
data. If the bit “job/handshake“ is the same, the response has been received. You should
implement a time monitoring.
5. Check, whether the bit “job/status“ is set. If the bit “job/status“ is not set, the field
“data/error“ contains the required parameter value. If the bit “job/status“ is set, the reading
job is not executed properly and the field “data/error“ contains an error information.
Write job
1. Determine the user-data range of the controller, i. e. determine the location of the DP
user-data in the host system.
2. Enter the address of the desired parameter in the field “Index and subindex“ (DP output
data).
3. Enter the parameter value into the field Data/Error.
4. Job/Service = Write job and the bit job/handshake must be changed (DP output data).
5. Check, whether the bit “job/handshake“ is the same for the DP input data and the DP output
data. If the bit “job/handshake“ is the same, the response has been received. You should
implement a time monitoring.
6. Check, whether the bit “job/status“ is set. If the bit “job/status“ is not set, the job has not
been executed properly and the field “data/error“ contains an error information. Otherwise,
the job has been executed without any faults.
