pascal Posted April 18 Report Share Posted April 18 I have several PLC's running to control a building (because I can only use 8 URB adapters on 1 PLC 😒😒😒) On 1 PLC, I communicate with my lighting system (HELVARNET - DALI) to ask the status of my lights. Because it's a huge building, it takes a while for scanning all lightsgroups. For every group, I have the status in a data table. But now I want to make this data table is also available for my other PLC's (so they don't have to ask my lighting system what's the state of the lights) I've tried to update the status with MQTT, publishing and subscribing all status of all lightgroups, but this is to slowly for me..... What's the easiest way to "send" my data table to the different PLC's ? any suggestions ? my data table is built with a structure of+- 15 elements (integers, bit arrays, string,...) -> size is 13200 bytes I need something that can be run in the background, because my scantime is already high.... -> +-50000 µs (so I could have problems with my 100ms timer....)
