Modbus read stop and poll value #418

Closed ecsauto closed 5 months ago

ecsauto commented 8 months ago

Which node-red-contrib-modbus version are you using?

v3.1.0

What happened?

I tried to implement the modbus tcp to read the input from Moxa iologik . 1st issue I encountered was the modbus read would stop without the error. I need to recreate the plug-in or restart the iologik to get it work again. The other issue is why I get 8 value from the DI if I only specific only 1 value.

Here is the capture of 2nd issue:- image

Server

Modbus-Server Node

How can this be reproduced?

What did you expect to happen?

I expect the read function will not stop working. and value of DI can be specified by the programmer. Thanks for your help in advance.
