TIA Portal Configuration for PUT/GET  Communication

To enable proper communication between an S7 PLC and our PLC using PUT/GET mechanisms, follow these steps in TIA Portal:

1. Settings for PUT/GET Communication

  • Open Properties of the CPU.
  • Navigate to Protection & Security → Connection mechanisms and check:
    • Permit access with PUT/GET communication from remote partner
      (allows data access via PUT/GET from external devices)

2. Settings for Data Blocks (DB) – OPC UA

  • Open the properties of the selected Data Block (DB).
  • In the Attributes tab change:
    • disable Optimized block access
Note:
Safety data blocks cannot be accessed via Simple CPU communication. In such case. the last option is enforced to be checked.
