When using MC read, there will be a timeout problem when inserting data

General
1

I just entered the field of Node-red, so I don't know how to use it yet. MC read is indeed connected to the PLC, but there will be errors when transmitting data. Is there any way to improve it, or increase the max age?

Also, my English is not very good, so it may not be fluent, sorry

Can you select the nodes (inject --> debug) and export (CTRL-E) them to clipboard, then paste the exported flow into a </> code block in your reply.

I try to use different port gates for MC READ and MC WRITE.
Then it's fixed
