270-003D

Access Table Configuration

Navigate to MOD function → Table Configuration → Select the affected table from the list.

Use softkey TABLE CONFIG to quickly access configuration options

Review Column Properties

Check column definitions and identify timestamp columns marked as read-only in the configuration display.

Do not modify system-generated timestamp columns

Remove Invalid Modification Key

Delete the modification key assignment from the read-only timestamp column using DEL key or RESET softkey.

Timestamp columns should never have user-defined modification keys

Validate Configuration

Press END key to save changes and verify alarm clears from the error display.

Open Tool Table Configuration

Press MOD key → Tool Management → Table Configuration → Select TOOL.T table.

Tool timestamp columns are critical for tool life tracking

Locate Timestamp Columns

Identify columns with names containing TIMESTAMP, T_TIME, or similar time-related designations in the column list.

These columns are essential for tool management integrity

Clear Modification Keys

Remove any modification key assignments from timestamp columns by selecting the column and pressing RESET MOD KEY softkey.

Only assign modification keys to user-editable tool parameters

Confirm Table Structure

Verify table configuration is valid by pressing END and checking that alarm 270-003D is cleared.

Access Workpiece Table Config

Navigate to MOD → Workpiece → Table Configuration or use PRESET table configuration menu.

Workpiece timestamp tracking is crucial for setup verification

Review Preset Timestamp Columns

Check for timestamp-related columns in preset tables (WP_TIMESTAMP, LAST_MODIFIED, etc.) and verify their read-only status.

Remove Conflicting Keys

Delete modification key assignments from any timestamp columns using the column configuration interface.

Preset timestamps ensure traceability of coordinate system changes

Save Configuration

Complete configuration changes with END key and monitor for alarm clearance.

Identify Custom Tables

Access MOD → Table Configuration → Review all custom or user-defined tables in the system.

Custom tables often inherit timestamp requirements from system tables

Analyze Column Definitions

Examine each custom table for columns designated as timestamp types or with automatic time-stamping properties.

Correct Modification Key Assignment

Remove modification keys from timestamp columns and reassign to appropriate user-editable columns only.

Timestamp integrity must be maintained even in custom tables

Test Table Functionality

Verify custom table operates correctly with proper timestamp behavior after configuration changes.
