Read Parameters

Requirements
● The PROFIBUS master has been commissioned and is fully operational.
● PROFIBUS communication between master and slave is operational.
● The master can read and write data sets in conformance with PROFIBUS DPV1.
Task description
Following the occurrence of at least one fault (ZSW1.3 = 1) the first 8 active fault codes must
be read from the fault buffer r0947[0] ... r0947[7]. The accompanied faults values of the fault
code are important for the user. These must be read from parameter r0949 [0] ...r0949[7].
The request is to be handled using a request and response data block.
Procedure
1. Create a request data block e.g. DB1 to read the parameters
