Wolfgang Eckart, Festo Didactic GmbH & Co The FB has 10 data records of 4 bytes each (for the LED ID, on status and flash status).Mechatronics Teachware FMS50 Conveyor MPS 2000 The SFC51 SZL_HEADER output is a structure consisting of the record length and the number of records. Once you look at the code, it is easy to see how that can be adapted to suit your need.
In this example, I use the system fault (SF) status and combine any of the bus faults (BUS1F, BUS2F, BUS3F). For this, you need to know the LED IDs (also documented in the FB): 0x01 SF Once the data has been obtained we copy it to a buffer for analysis, since it is not retained between reads.Īfter the data has been copied, it is a matter of looping through the records to pick out the ones that are of interest. This particular FB I have used without modifications in the S7-300 CPUs 315, 316, 317, 318 and 319.
The number of records that are returned is CPU dependent. The header will contain the record length and the number of records that were returned. We will use SFC51 RDSYSST (Reading a System Status List or Partial List) with SSL_ID 0x19 to obtain the status of all LEDs at once. In this function block, we only output the status for system fault and a combined bus fault (for any interface), but you can easily change that. This function obtains the status of the CPU LED indicators, for visualization on an HMI, for example.
