DIAGNOSTICS · PROTECTION · COMMISSIONING

Reliable operation with structured installation guidance

◆ Diagnostic protection

Channel status and controller diagnostics support identification of sensor-side faults.
Separate RTD input channels simplify comparison and localization of abnormal readings.
Configured measuring ranges help detect incompatible sensor or wiring assignments.
Stable module identification supports consistent hardware diagnostics in the project.

◆ Installation & upgrade

Mount the signal module beside a compatible SIMATIC S7-1200 CPU.
Wire the eight RTD inputs using the sensor connection method defined in the module manual.
Configure sensor type and measuring range for each channel in TIA Portal.
Verify channel values and diagnostic status before placing the control loop in service.
