9.2.2.1 Reading parameter data from the controller
General procedure:
1. Define the user data area of the controller, i.e. define the location of the DP user data
in the host (observe manufacturer-specific information).
2. Enter the address of the required parameter in the "Index" and "Subindex" fields (DP
output data).
3. Request in the service byte = read request.
– The handshake bit in the service byte must be changed (DP output data).
4. Check whether the handshake bit in the service byte is the same for the DP input data
and the DP output data.
– If the handshake bit is the same, the response has been received.
– It is useful to implement a time monitoring tool.
5. Check whether the status bit in the service byte is set:
– Status bit isnot
set: The "Data/Error" field contains the required Parameter value
(data) ( 47).
– Status bit is set: The read request has not
been executed correctly. The "Data/Error"
field contains the Error codes
( 48).
9.2.2.2 Writing parameter data to the controller
General procedure:
1. Define the user data area of the controller, i.e. define the location of the DP user data
in the host (observe manufacturer-specific information).
2. Enter the address of the required parameter in the "Index" and "Subindex" fields (DP
output data).
3. Enter the parameter value in the "Data/Error" field.
4. Request in the service byte = write request.
– The handshake bit in the service byte must be changed (DP output data).
5. Check whether the handshake bit in the service byte is the same for the DP input data
and the DP output data.
– If the handshake bit is the same, the response has been received.
– It is useful to implement a time monitoring tool.
6. Check whether the status bit in the service byte is set:
– Status bit is not
set: The write request has been executed correctly.
– Status bit is set: The write request has not
been executed correctly. The "Data/Error"
field contains the Error codes
( 48).
