Use EIPInit() with error 32052 Illegal tag type

Hello,

We use the EIP Library meet an error 32052, what is the mean of Illegal tage

In this issue, we changed the datatype from BYTE to SINT and the error disappears, what is the reason?

And If anywhere we can find more explanation about this EIP library, we found too few information about this.

This library is rather old and back in this time B&R PLCS did not support “BYTES”
Therefor only USINT or SINTs are allowed for 1 byte values
