Summary
Convert from Siemens S7-1200/1500 (Symbolic Addressing) to Siemens S7-1200/1500 (Absolute Addressing).
Solution
The following steps explain how to change the driver from Siemens S7-1200/1500 (Symbolic Addressing) to Siemens S7-1200/1500 (Absolute Addressing). After changing the driver, users can still use the tag names of Symbolic Addressing driver for objects in EBPro.
Steps to change from Symbolic to Absolute:
1.
In TIA PORTAL, please deselect this option for each Data Block: [DB UTILITAIRES] » [Attributes] » [Optimized block access]. Please note that deselecting this option is necessary for every Data Block.
2.
Save the project and compile it, then save and close the project in TIA PORTAL.
3.
In EBPro’s device list:
Change Siemens S7-1200/S7-1500 (Symbolic Addressing) (Ethernet) to Siemens S7-1200/S7-1500 (Absolute Addressing) (Ethernet) driver, and configure the connection parameters.
4.
Click [Import Tags] and import the TIA PORTAL project again.
5.
After import, the following message shows, please select (N).
