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](https://github.com/SerafinTech/ST-node-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](https://github.com/st-one-io/node-red-contrib-cip-ethernet-ip) there is still an [open issue](https://github.com/st-one-io/node-red-contrib-cip-ethernet-ip/issues/17) for string support.

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