Access Safety Configuration

Navigate to MOD > CfgSafety > inpNoDynTest and identify the specific SPLC input number from alarm text.

Document the input number and corresponding safety device before starting diagnostics

Check Physical Connections

Inspect X118/X119 safety connector pins for the affected SPLC input, verify tight connections and absence of corrosion.

Power down system before inspecting safety connectors

Measure Continuity

Use multimeter to verify continuity from safety device through to SPLC input terminal, check for open circuits or high resistance.

Typical safety input resistance should be <1 ohm end-to-end

Test Dynamic Response

Monitor SPLC input status in PLC > Status > Safety I/O while manually activating safety device to confirm proper switching.

Input should switch within 10ms of device activation

Identify Safety Device Type

Check machine documentation to determine if SPLC input connects to door switch, light curtain, or other safety device.

Safety device type determines appropriate testing method

Perform Manual Device Test

Manually actuate safety device while monitoring input status in PLC > Status > Safety I/O to verify mechanical operation.

Follow lockout/tagout procedures when testing safety devices

Check Device Test Outputs

Verify test output signals reach safety device by measuring voltage at device terminals during dynamic test cycle.

Test outputs typically pulse 24VDC for 100-500ms during dynamic test

Replace Safety Device

If device fails to respond to test signals, replace with identical safety-rated component and verify proper wiring.

Only use safety devices with matching or higher safety category rating

Review Safety Configuration

Access MOD > CfgSafety and verify inpNoDynTest parameter matches actual safety device requirements.

Parameter should be 'false' for devices requiring dynamic testing

Check Test Output Assignment

Verify correct test output is assigned to SPLC input in safety configuration, confirm output number matches wiring.

Test output assignment must match physical wiring for proper dynamic testing

Validate Test Timing Parameters

Check safety test cycle timing parameters in CfgSafety to ensure adequate time for device response.

Increase test pulse duration if safety device has slow response time

Save and Restart Safety System

Save configuration changes and perform safety system restart via PLC > Safety > Restart to apply new parameters.

Safety system restart will interrupt machine operation

Check SPLC Module Status

Navigate to PLC > Status > Hardware and verify SPLC module shows no error indicators or fault codes.

Red status indicators typically indicate hardware faults

Swap Input Channels

Temporarily move safety device wiring to unused SPLC input channel and update configuration to test module functionality.

Document original wiring before making changes

Monitor Input Diagnostics

Use PLC > Diagnostics > Safety I/O to monitor input signal quality and response times during testing.

Compare signal characteristics with known good inputs

Replace SPLC Module

If hardware fault confirmed, replace SPLC module with identical part number and restore safety configuration from backup.

SPLC module replacement requires safety system recertification
