Online connection with S7-1500 (eg CPU1512SP)


Sample configuration for a Siemens CPU 1512SP-1 PN.

This configuration should actually apply to all S7-1200 and S7-1500 CPU’s. However, there are still problems with practical experience. So far only the 1512SP has been tested.
Important : For communication to the S7-1200 / 1500 to work, the following must be observed:

  • The PUT / GET query must be allowed in the CPU settings.
  • For data blocks that are queried, the optimized block access must be switched off.
