I/O Module Does Not Support Hot Swap

Hva betyr E4-9526 ?

An I/O module that does not support hot swap functionality has been detected on a hot swap terminal unit. This configuration mismatch can lead to improper operation, module damage if removed/inserted while powered, or general system errors. Modules not designed for hot swap require specific handling.

• Installation of an I/O module that is not designed for hot swap functionality into a hot swap-enabled slot.
• Human error during maintenance, replacing a hot swap capable module with a standard, non-hot swap module.
• Incorrect part number ordered or selected from inventory, leading to an incompatible module installation.
• System configuration parameter (e.g., P_MOD_HS_CAPABLE) incorrectly set for the installed module type.
• Firmware version of the hot swap terminal unit or controller is too old to properly identify newer hot swap modules.

1. 1

   1. Verify the part number of the installed I/O module against its technical specifications for hot swap compatibility.

2. 2

   2. Remove the incompatible module and replace it with a module explicitly designed to support hot swap operation.

3. 3

   3. Check the PLC hardware configuration (e.g., P_SLOT_HS_STATUS) for the slot to ensure it matches the required module type.

4. 4

   4. Review the system's Bill of Materials (BOM) or engineering documentation to confirm the correct module for the slot.

5. 5

   5. Consult the manufacturer's manual for specific hot swap module requirements for the terminal unit model.
