The data cannot fit into an ICM telegram (_ecICM_TELEGRAM_OVERFLOW)

Hva betyr 223 ?

This fault occurs when the amount of data being sent by the system exceeds the maximum capacity of an ICM (Industrial Communication Module) telegram. This typically happens in host applications using doMultipleCommands with too many encapsulated calls, preventing proper data transmission and potentially causing communication timeouts.

• Excessive number of parameters or variables configured for cyclic data exchange within a single ICM telegram.
• Host application attempting to send or request a data block larger than the maximum payload size of an ICM telegram.
• Misconfiguration of the ICM module's telegram structure, allocating insufficient space for the data.
• Firmware bug in the ICM module or the drive leading to incorrect telegram size calculations.
• Attempting to encapsulate multiple large data structures into a single communication frame.

1. 1

   1. Reduce the number of parameters or data points configured for cyclic transmission within the ICM telegram.

2. 2

   2. Divide the large data block into smaller chunks that fit within the maximum ICM telegram payload size.

3. 3

   3. Review the ICM module's configuration to ensure its telegram structure is optimized for the data being exchanged.

4. 4

   4. Check the documentation for the specific ICM module and drive for maximum supported telegram sizes.

5. 5

   5. Update the firmware of the ICM module or the drive if there are known issues with telegram handling or size limits.

6. 6

   6. Utilize alternative communication methods or multiple telegrams if a single telegram cannot accommodate the required data.
