i think for something like this you need to do custom programming. this custom programming then has the advantage: 1. smart, saves bandwith, etc. disadvantage: 1. maintainability. Usually in factories this is done by one person, and the other persons never touch it (in fear of breaking something). Also using something like Node-RED you need to consider that this needs to be kept up-to-date, and with Node-RED being based on NodeJS which releases two major versions per year, it is a significant effort to keep it updated our approach here is to always prefer maintainability over bandwith. better to spend some money on better infrastructure, than to costs of being never able to update your systems (e.g., security) or everyttime you want to do something you need to hire an SI. there are a lot of cases where PLCs cannot handle that load, in those cases a compromise needs to be done. the case you are talking about sounds interesting. gigabit can have over 100MB/sec. so something must have been really unoptimized here in order to reach that. I assume the PLCs simply cannot handle a lot of data pointsper second.
