basicS7 Libs

[mcmullan]

I need some assistance in using the S7 standard objects in a Pvss project. I need some the steps on what it takes to connect the pre-defined data types in PVSS to the correct address in the PLC itself.

Hello,

the connection between the datapoint-element and the address in the PLC is made at the _address-config at the datapoint-element.
The common settings (input/output, datatype, ...) are made at the master-datapoint. At the instances the correct address has to be defined.

Hello Leo,

Thanks for this information. I appreciate it.

One other quick question...
If you add one of the objects from the basicS7_valveOpCl group to a panel would you normally need to write any scripting to make it work? Also, Do you have an example of the PLC programming part where this is working? I need some examples of how the FB are programmed in the PLC.
Any suggestions, helps or hints to get this working would be very helpful.

Thank you,

Rick McMullan

Hi Rick,

From my experience using the S7 driver, there are no particular guidelines you need to adhere to as the driver simply reads data from whatever PLC register you tell it to. I cannot help you with the _valveOpCl object however as I have never used it.

Hello,

the objects should work without addirional scripting.
Before you can use these objects you have to import the datapoint lists for the Std- and the S7-basic-library.
Afterwards you've to create the datapoints for the objects you want to use.
