Jeremy Theocharis commented on PLC4X-315:
-----------------------------------------
Hi Lukas,
thank you for your answer! Thank you also for your edits regarding the Go
implementation. We are especially impressed by the various plc drivers and
various programming languages this project supports.
I have some additional questions, which we could also discuss in a call:
# What is the reason for the PLC4X project? What is the advantage compared to
using e.g., {color:#172b4d}Snap7 or open62541? We are currently deciding
whether we want to use established libraries or PLC4X (strategic
decision).{color}
# Related to the first question: What is the financial backing behind this
project? How do you ensure that it is maintained in the future?
# I assume that the Java implementation is the most stable one, correct?
# How would you approach our following idea?: We want to create a configurable
microservice that automatically takes data from various PLCs (especially
OPC/UA) and pushes them into a MQTT broker. Therefore, we would need the
"functions" browse and subscribe. As far as I can see the Go implementation
does not support OPC/UA yet so we should use Java, correct?

> Hi everyone!
> My name is Jeremy and I am the lead developer of the United Manufacturing Hub.
> The United Manufacturing Hub is an open-source industrial IoT and
> manufacturing application platform enabling users to connect, store, and
> access all relevant data sources in industrial manufacturing sites and build
> user-centric dashboards and applications.
> It would be really great if we could make a connection between PLC4X and the
> United Manufacturing Hub, e.g., in form of a configurable microservice that
> automatically takes data from various PLCs and pushes them into a MQTT
> broker. The United Manufacturing Hub (incl. Node-RED, Grafana, timescaleDB,
> VerneMQ) then provides the infrastructure and data models to contextualize
> the data and enable use-cases like OEE, Performance Management, Machine to
> Machine Communication, Digital Shadow, etc. Furthermore, the United
> Manufacturing Hub allows extracting data from other data sources as well like
> sensors, barcodereader or cameras.
> Further information can be found here:
> * [https://docs.umh.app/docs/]
> * [https://github.com/united-manufacturing-hub/united-manufacturing-hub]
> Looking forward to discussing how we can combine both open-source projects
> the most effective way.
> Regards,
> Jeremy
