Simatic S7 Driver :: DB Number and Offset

[yeshwarya]

Dear Team,

I had created one Valve Structure in 'Para". I am using S7-400 PLC and TCP/IP connection in Wincc-OA.

For each DPE of Valve, I define peripheral address as free address and Simatic S7.

For 1 valve i define all the address and data type of each DPE manually.

But for number of Valve it will quite hectic. I created Master data point but i think it will only work for to define structure and data type but not convenient for addressing.


Is there any way for addressing of each DPE.


In WinCC there was future, that Just create the structure, define all address and offset. For other tag, just change the address and offset and it will apply to all DPE element.


Is there same way in WinCC-OA for addressing.

When using master datapoint and power configs for the _address configs it is possible to add automatically address information which possibly fits the data point element.
If this is possible depends on the driver and the power config which is used.

E.g. when using OPC DA addresses it is possible to replace the OPC tag ID with the current DPE name if a new datapoint is created.
I'm not sure if such a logic is also possible when using the S7+ driver.

If you want to create new datapoints with specific addresses you can use a ASCII file in format V3/V4. In the file you have to define the datapoint name and the address. Other settings which are predefined at the master datapoint and which are not define as changeable in the power config must not be defined in the ASCII file.
