Omron SYSMAC N-Smart Series Library

An input value provided to the function block is outside its permissible range. This can apply to the Node Address (NodeAdr) or the Directory Name (DirName), which may contain invalid characters or exceed length limits.

The system failed to access the SD Memory Card. This issue can stem from the card not being present, improper insertion, physical damage to the card itself, or a faulty SD Memory Card slot on the CPU Unit or Industrial PC.

An operation attempted to write data to an SD Memory Card that is currently protected against writing. This prevents any data modification or new file creation on the card.

The SD Memory Card has run out of available free space, preventing new data from being written or existing files from being modified if it requires additional space.

No backup file for restoration was found in the directory specified by the DirName parameter. The restore function block requires a valid backup file to be present at the specified location.

The function block attempted to access a file (for reading or writing) that is currently locked or being used by another instruction within the system. Concurrent access attempts to the same file are not permitted.

A backup operation was attempted to create a file with a name that already exists on the SD Memory Card, and the OverWrite parameter of the function block is set to FALSE, preventing automatic overwriting.

The function block attempted to write data to a file or directory that has write protection enabled. This prevents the creation or modification of files in that specific location.

The system reached its maximum limit for simultaneously open files when the function block attempted to open an additional file. This indicates an excessive number of active file handles.

The system failed to access the SD Memory Card due to a hardware malfunction. This can be caused by a damaged SD Memory Card or a faulty SD Memory Card slot on the main control unit (CPU Unit or Industrial PC).

The EtherCAT network is not in an operational state, preventing successful communication between devices. This could be due to issues with the EtherCAT master or the network infrastructure itself.

The specified EtherCAT slave device failed to respond to communications. This can occur if the slave address is incorrect (target slave does not exist) or if the slave is not powered on or in an operational state.

The system failed to receive a response from the target EtherCAT slave within the allotted communication timeout period. This indicates a communication delay or a lack of response from the slave device.

The data received from an EtherCAT slave exceeded the capacity of the assigned reception buffer, leading to data loss. This occurs when the incoming data rate or size is greater than the buffer can handle.

A Service Data Object (SDO) communication operation with an EtherCAT slave resulted in an abort. The specific cause is indicated by an associated SDO abort code, which varies depending on the slave's specifications.

The system attempted to execute more than 32 EtherCAT communication instructions concurrently, exceeding the maximum allowable limit. This indicates an overloading of the communication resources.

The VenderID (Vendor ID) found in the object lists does not correspond to the VenderID of the device targeted for backup. This indicates a mismatch between the expected and actual device identification, preventing the backup operation.

The ProductCode found within the object lists does not correspond to the ProductCode of the device targeted for backup. This indicates an inconsistency between the expected and actual product identification, preventing the backup operation.

A connected Sensor Amplifier Unit is not compatible with the function block being executed for backup. The function block cannot process data or operations for this specific unit type.

The device specified for the backup function block operation is not compatible. This function block is specifically designed for E3NW Units and will not operate with other device types.

The VenderID (Vendor ID) contained within the backup file does not match the VenderID of the device targeted for restoration. This prevents the restore operation due to an identification mismatch.

The ProductCode contained within the backup file does not match the ProductCode of the device targeted for restoration. This prevents the restore operation due to an identification mismatch.

The revision number of the E3NW Unit designated as the restore destination is older than the revision number recorded in the backup file. This prevents restoring an older device with a newer configuration.

The Sensor Amplifier Unit configuration stored in the backup file does not match the actual configuration of the Sensor Amplifier Unit connected to the restore target node. This mismatch prevents a successful restoration of settings.

The device specified for the restore function block operation is not compatible. This function block is specifically designed for E3NW Units and will not operate with other device types during restoration.
