Fault analysis is becoming an increasing challenge for complex plant and machinery installations. High-resolution signals need to be recorded over long time periods, and the number of signals continues to rise.
Basic data loggers are often incapable of processing extensive numbers or types of signal. The capacity and quality of data storage is vital as is the availability of trigger functions.
Meeting user requirements
Message devices enable users to use a single unit to acquire digital and analog signals as well as data from bus systems such as Modbus-TCP/RTU or PROFIBUS-DP. PLC data or sensor data (from RTDs, thermocouples, pressure sensors, strain gauges, …) are saved directly to the device's internal data storage (up to 16 GB for ca. 2 billion time-stamped data records). Internal storage systems are partitionable and support trigger-based recording. The systems include variable pre and post-trigger times.
Small, compact and powerful
The compact Message devices (W 200 x H 73 x D 118 mm) are crammed with fault analysis technology. Virtual channels are used to generate alarms, enter computations, monitor threshold values and logic functions directly within the hardware. The compact design makes it ideal as a fixed or temporary cabinet installation.
Mobile service systems
Robust case systems are available as mobile fault diagnostic systems. These contain contain Message devices along with equipment such as power adapters, filters, amplifiers, UMTS modems or voltage dividers. Connections are externally accessible: 4mm safety lab plugs, spring clamps and screw terminals according to user requirements.
The mobile measurement case is designed with lid-based cable-feeds and can therefore be used when closed. The cases can be secured with a locking system for long-term deployments.
Online or offline data transfer
Data stored in the device can be evaluated at a laptop or PC workstation using the ProfiSignal software. Remote online monitoring as well as triggered and manual memory read-outs are possible via a network (internet/intranet/UMTS connection).
Direct link to alarm lists and trend analysis deliver high-resolution fault diagnostics
Using existing online pathways, the ProfiSignal AlarmManagement issues alarms to the appropriate personnel via email, fax or text messaging.
Fault data acquisition enables an alarm or malfunction to be immediately analysed. Clicking an alarm list entry automatically opens a trend diagram showing the fault data for the relevant signals. Pre and post-trigger times for fault events can be set according to user requirements. Fault events can be portrayed using high-resolution data and at millisecond precision for both online and archived data.
