Thank you Steve for the reply. Much appreciated. I have never heard of this 100 Word limitation.
Cause we're already hammering our PLCs with 2,000 data per second for SCADA communication via Modbus TCP.
With NodeRed, I intend to connect several PLCs and ingest data at 10,000 data point per second as a TCP string.
Regardless, the above experience you mention does concern me now. What hardware are you using? I intend to use the Modbus Library https://flows.nodered.org/node/node-red-contrib-modbus
