Hi all, I am writing as we have been working on the Apache Nifi integration part of the project. We have created a Record oriented processor for reading PLC data. It is based on the previous existing SourceProcessor, but works with records, using a Nifi Writer (such as Avro, Json, and so on) to write data on flowfiles content.
We updated the code on our fork with the actual PLC4X git repo about 2 weeks ago, and tested it reading values with S7 from a S7-1200 CPU from Nifi. Also, one of our customers has recently started to use it for validation. Currently, it works with S7 and Modbus over TCP. This is because we had to write some classes to map connectionString and variableList properties (sintax) of the processor to the actual protocol, to be able to build then avro schema for output flowfile, taking into account variable datatypes, etc. We only did this for S7 and Modbus. I am sure that there is a better way to do this, so at this point you maybe could take a look to find the best solution and avoid needing to do this mapping. If you find this useful, we could do a pull request to the main PLC4x repo. Let us know what you think. best regards, iñigo ----------------------------------------- Iñigo Angulo ZYLK.net :: consultoría.openSource telf.: 747412337 Ribera de Axpe, 11 Edificio A, modulo 201-203 48950 Erandio (Bizkaia) -----------------------------------------
