Comprehensive signal processing

LogMessage devices are equipped with a range of internal calculation, monitoring and logic functions that are set up as "software channels". These channels process online measurement data and make it available for visualization, storage or control purposes.

 

Process and control functions enable the simple and intuitive configuration of complete programmable procedures. These then run independently without the need for any PC support. Users can efficiently deploy their data loggers as monitoring and PLC equipment.

Limit values

Limit values for alarm output and event management. User friendly functions for determining normal operating conditions. Integrated wire-break monitoring.

Calculation channels

Computational linked channels. Differential measurements, quotients, efficiency rates, output performance etc., and the recording and evaluation of a calculation channel takes place in the same way as for a hardware channel. Averaging channels and statistical functions

PID controller

Simultaneous multiple controllers. Automatic and real-time settings as default parameters.

Integrators

Integration and differentiation of measurement data (e.g. flow rates to volumes). Includes functions for operating time counters, edge counters and totallers.

Timer

Targeted generation of edges and impulses in digital outputs. Simple tool for controlling external set-ups.

Alarm functions

Independent transmission of fault notification messages as email or text message. Requirements: Network operation or GSM modem.

COM and Modbus channels

Serial interfaces for connecting weighing machines or large displays via RS232/422/485, protocol generator for ASCII protocols, Modbus RTU and Modbus TCP (client/server).

Set points

Generation of set point graphs for internal/external use. Operating external equipment (e.g. controller). Monitoring processes on a PC.

Linearisation channels

Pre-programmed sensor linearisation and user-defined sensor characteristic curves (up to 7,500 value pairs).
