I/O Bus Master Parameter Setting Error

What does E2-17 mean?

An error occurred while attempting to set a parameter for the I/O bus master. This indicates a problem with configuring the communication master, potentially preventing it from correctly initiating or controlling connected I/O devices. This can lead to a complete loss of I/O communication.

• Attempting to set an invalid or out-of-range value for an I/O bus master parameter (e.g., P3-01 Baud Rate).
• GSD file (General Station Description) for the I/O bus master is corrupted or incorrect.
• Communication conflict with another device on the same bus trying to write parameters.
• Firmware bug in the I/O bus master preventing proper parameter handling.
• Hardware fault in the non-volatile memory storing master configuration parameters.

Click steps to track your progress.

1. 1

   1. Review the I/O bus master's configuration parameters (e.g., Profinet name, IP address) in the engineering software for correctness.

2. 2

   2. Download the I/O bus master's configuration (e.g., via TIA Portal) to ensure parameter integrity.

3. 3

   3. Perform a factory reset of the I/O bus master module.

4. 4

   4. Verify the device master file (e.g., GSDML for Profinet) for the I/O bus master is current and valid.

5. 5

   5. Check the 24VDC power supply stability for the I/O bus master module at its terminals.
