Some Plcs going offline after updating st-ethernet-ip #40

Describe the bug

After updating library st-ethernet-ip (used by node-red-contrib-cip-st-ethernet-ip 2.0.0-beta.3) from 2.5.3 to 2.6.1 some plcs was signed as offline by eth ip in, but this is not true (all work well).

How to solve problem

Going deeper thru the problem, I focused on a PLC from which I read only one element x.y[50] : x is a struct, y is an array of 64 DINT, it was enough to change type from DINT to empty (in plc tags configuration on nodered), after deploy plc was signed online and all go well.

Expected behavior

Eth ip in must not sign offline a plc that work and that is well configured.

Environment

i was facing the same problem, then i read all struct using data type Struct, the output type was a object then i filter it out of my requirement.

I'm facing a similar issue, where the struct element is read only once after restarting the flow, and then nothing. Reading the entire struct works though.
