Sending string value to rockwell compact logix plc

Industrial

Hi,
I am trying to read string value from Compact Logix plc via node-red-contrib-cip-ethernet-ip nodes,
all other datatypes like DINT, INT, Real, and BOOL are working but i am not sure how to read string values, any pointers.

node-red-contrib-cip-ethernet-ip is build on top of st-ethernet-ip. On the readme of st-ethernet-ip you can read:

"Currently, the Tag Class only supports Atomic datatypes (SINT, INT, DINT, REAL, BOOL). Not to worry, support for STRING, ARRAY, and UDTs are in the plans and coming soon! =]"

On the github page of node-red-contrib-cip-ethernet-ip there is still an open issue for string support.

It looks like you have to wait for string support, or use one of the mentioned workarounds in the issue above.

Thanks for the update, will try to play around with work arounds
