Not Supported Protocol Variant

¿Qué significa E3-8480 ?

The I/O bus module has detected a communication protocol variant that is not supported. This indicates an incompatibility in communication standards between the module and other devices, preventing proper data exchange and potentially halting the module's operation. This is a configuration or firmware mismatch.

• Mismatch between the I/O module's firmware and the protocol version used by the master device (e.g., CPU, fieldbus coupler).
• Incorrect protocol selection in the I/O module's configuration (e.g., set to Profinet IRT when master is Profinet RT only).
• Attempting to connect an I/O module that supports an older or newer standard than the current network configuration.
• GSDML (Generic Station Description Markup Language) or ESI (Electronic Device Description) file mismatch in the engineering software for the module.
• Hardware variant of the I/O module not compatible with the selected protocol configuration (e.g., specific hardware revision required for newer features).

1. 1

   1. Verify the exact model number and firmware version of the I/O module and compare it with the required protocol variant specified by the system integrator or machine builder.

2. 2

   2. Check the communication protocol settings in the engineering software for the I/O module (e.g., Parameter P10-01 Protocol Type, P10-02 Protocol Version).

3. 3

   3. Update the I/O module's firmware to match the protocol version of the network master (e.g., CPU, fieldbus controller).

4. 4

   4. Ensure the correct GSDML/ESI file for the specific I/O module model and firmware version is imported into the engineering software.

5. 5

   5. If the module has physical configuration switches for protocol selection (e.g., DIP switch 1), ensure they are set correctly according to the manual.
