Siemens Alarms SINUMERIK 840D sl, SINAMICS S120 Alarm Diagnostics

Accurately diagnosing faults and alarms as quickly and specifically as possible help achieve optimal performance and helps avoid mechanical failures. When the integrity of your automation system is monitored inefficiently it impacts all the components and can negatively influence performance and alter cost efficiency for overall building operation. Whether you are a project engineer, commissioning engineer, machine operator, or service/maintenance personnel, adopting fault detection in building management is a key strategy to cut costs, save energy, and better use resources.

Understanding Siemens diagnostics

We will be covering Siemens alarms and messages from the NC area, HMI, and SINAMICS. This article will aid in three areas.

· Assess special machine operation situations.

· Ascertain the reaction of the system.

· Use applicable possibilities for continued operation.

Alarms and faults and two different signals, but they are more complementary than adversarial. An alarm brings notice to the building automation system when the critical status is reached within the system. It does not alter the performance but allows the operator to know when a specific threshold has been breached. A boiler exceeding the max temperature is an example of a unique variable changing triggering an alarm. This alerts the operator that something is not right while all the components continue to operate as usual. Putting the operator in the defensive is not most advantageous.

Faults are system detections that are intended to prevent these situations. How do they do this? Faults connect to the building automation system and data points allowing them to identify faulty equipment or mechanical failure. Before an alarm is triggered, the fault allows the operator to be proactive, effectively handling disturbances within the complex system.

Armed with this knowledge, let’s delve into evaluating errors and fault indications to better learn how to respond. We will look at various diagnostic options and diagnostic tools available.

The structure of the NC, HMI, drive and I/O alarms are all the same. Each alarm is uniquely identified. Identification is unique using an alarm number and an alarm text. The alarm description is administered in one of four categories: Explanation, Response, Corrective, Program continuation.

The SINAMIC alarms are detected by the individual components within the drive system. These are categorized as faults and alarms. The alarms are identified by alarm number and alarm text with an optional location data display.
