Hi all,

I'm currently working on a project with Node-RED.  
The task at hand is to regulate the current supplying an equipment between 4-20mA, and for that I am using a Brainbox ED-560, Node-RED and Modbus Nodes.

Does anyone here have any experience with using Nodes that are able to regulate what current a Modbus-node outputs? I have tried using basic nodes like a Slide-node connected to the Modbus-node, but this does nothing to the current output.

Any help will be greatly appreciated.

Best regards,  
Alexander
