I would like to use Node-Red to update the time in 20 PLCs and am using FINS Write. I am fairly new to Node-Red and would like an opinion on if I can write all 20 PLCs at once (Connect Parallel) or should I connect them all in sequence with the message passing through each write node to the next.

Don't see why it wouldn't work all at once. Each plc connection is a separate communication path. Give it a go. Let us know.

Looks like it worked...Was just a little worried about doing too many things at the same time.  
Thanks.
