Can't write to KepServer V5 word tag with uint16 type - by: Taid

Hello,

I'm creating a small asp.net page to help control data flow between MySQL and S7-300 PLC on one of our machines and I run into a weird road block in writing to a tag which on server is declared as WORD and it's type should be a simple integer on the PLC. As a side note, I'm still using the trial version (version 5.52.91.1) and this is the last point before we make a purchase of your OPC client.

I did try using EasyOPCUADemo and connectivity explorer but the result seems the same. I get no error when the value type declared is UINT16 but no value is written on the PLC. If I go with any other type I do get the BadTypeMismatch error.

Response of connectivity explorer when no value type is specified:

Testing with WriteValue and WriteMultiple yields the same results (no error no value on PLC).
