Read string function throws an error when used with an S7 1200
An error is reported when reading a string from the S7 1200 PLC. The LabVIEW error code is 510324 and the SPS error code is 0x8500.
After debugging the code and testing with workaround it seems to be, the S7 1200 can not handle reading requests with a Read Length of greater than 222 Bytes. The Read Length in the S7NetCom Read string function is set to 256 Bytes.
Would it be possible to change the constant read length to an input control?
