IEC104 Double Command Issue

IEC104 Double Command Issue

Hi,
I'm using Zenon 7.20 to communicate with SYS600 9.3 (ABB) Gateway through IEC104.
When I do Process Command (T46): Select then Confirm ---> Close or Open Ok!
Select then Cancel = Select then Confirm.
Select then Exit = Select then Confirm.
The Command Process that I'm using is a template control element.
Could you please help me to solve this.
Thanks & Best Regards,
MinhKV
