Hello, it should be possible. You can connect TO via data block to the drive, when the available telegramm is not suitable. https://support.industry.siemens.com/cs/ww/en/view/109781848 5.4 Connect drive/encoder via data block (S7-1500, S7-1500T) Creating the data block for data connection 1. Create a new data block of type "Global DB". 2. Select the data block in the project tree and select "Properties" from the shortcut menu. 3. Disable the following attributes under Attributes and accept the change with "OK": – "Only store in load memory" – "Data block write-protected in the device" – "Optimized block access" for technology version < V4.0 4. Open the data block in the block editor. 5. Create a new tag on "Add" in the block editor. 6. For the new tag, enter "PD_TELx" completely in the "Data type" column. The "x" stands for the telegram number. Example: "PD_TEL5" for standard telegram 5 You have created a tag structure of the type "PD_TELx". This tag structure contains the "Input" tag structure for the input area of the telegram and the "Output" tag structure for the output area of the telegram. Note "Input" and "Output" relate to the view of the closed loop position control. For example, the input area contains the actual values of the drive and the output area contains the setpoints for the drive. For the data connection via a data block, "Input" and "Output" must always be in of the "PD_TELx" tag structure. Do not use standalone tag structures for "Input" and "Output", such as "PD_TEL5_IN". The data block may contain the data structures of multiple axes and encoders and other contents.
