How many PCS7 motor blocks can S7 315-2dpfc hold?

Your thinking method is basically not feasible: 1. The original project used PCS7, so it is estimated that CFC and SFC will be used, that is, the driving block, motor block, PID block and so on will be basically used. However, the actual size and functions of these functional blocks are very powerful, and the amount of programs must be larger than that of S7, which puts higher demands on the processing power and memory of CPU. 2. If S7-300 series products are used, which program in PCS7 is basically unavailable; Re-plan your project and re-program, because 3 15 is best not to program with CFC; And it is best not to use the function blocks in PCS7 library; 3. Although variable labels in WINCC can be uploaded by TRANSFER, uploading alarm information, archive records, picture trees and icons cannot be realized in PLC. So to downshift, you basically have to rewrite the program.
