Issue with standalone

Hello,

i'm having a little issue with the Stand Alone („Ready-for-use“ for legal-for-trade stand-alone operation without SIMATIC CPU) project.

I've downloaded the whole project, managed to make the WP251 communicate with the TP700. So my legal-for-trade display is loaded and working. The only problem I have now is whenever I try to send a command ( >0<, TARE, higher resolution, ...) the HMI is saying: "tag WP251_SCALE_1_s_CMD2_bo_CMD_TRIGGER that the value can not be written to the PLC". Wich is kinda logical since i'm not using any PLC.

How can I make sure the commands get through and let the WP251 get on zero for example by pushing a >0< button?

Is there anything to be changed to the script? Or is it something else?

The components I use is:

TP700 Comfort

WP251

Thank you in advance.

Hello Lévy,

the message "tag WP251_SCALE_1_s_CMD2_bo_CMD_TRIGGER that the value can not be written to the PLC" indicates that the value could not be written to the "partner" that is defined in the connection in WinCC.

In your case it is the Siwarex WP251 not a PLC.

May be the Siwarex WP251 has not the standard IP address. Try to set the IP address of the Siwarex WP251 to 192.168.0.21, the it should work.

 Thank you, I had some troubles with the IP-adress. They weren't in the same range.
