Hi Julie and j2mod community, We are using the library as a gateway to RS232 devices and need multiple process images. Is there a way to have multiple proicess images in j2mod? Has anyone considered adding support for multiple process images or has my team overlooked support for this?

Hi Julie, Hi Mark,
we're having the same question here.
For a plc simulator we'd like to run several (5+) Modbus-TCP slaves within the same application.
If I understand it correctly, the issue is the Singleton of ModbusCoupler.getProcessImage() which is referenced in many places throughout j2mod.
An option woud be to split each simulator into a separate application / microservice. Still this would be a pain with UI and automatic test scripts.
Any Ideas?
