Hello, trying to use node-red-contrib-cip-ethernet-ip. I want to read many variables from an Allen Bradley PLC but with different read-rate, so I wouldn't like to configure the tags and read-rate in the 'eth-ip' node. In a function node, I would like to organize and collect the data I need to read at the same rate in a JSON object and then send the information in msg.payload to the 'eth-ip in' node.  
For example something like this:

Is there any way to do it? Is there another package to use?  
Thank you.
