String FIFO in APROL

Ask Questions
1

Hello together!

I need a String FIFO block for MQTT Handling.

I’d like to know if there is an FIFO Functionblock for Strings in APROL having the following specs:

  • SSTRING Input
  • SSTRING Output
  • SSTRING Buffer (configurable Size of array)
  • If Input Strings changes, store it in the FIFO
  • Every second (external trigger also OK) the oldest String in the buffer is given to the output

Does somebody use such a functionality already?

Thanks in advance!

I asked APROL team and they do not have any FB prepared. But to develop such a FUB should not be work for hours. Maybe you can develop one and share it here? :slight_smile:
