3.1 General Information
3.1.1 System Overview
The Control, Measurement and Data Logging system (CML) is designed to add remote control
and monitoring functionality to electronic systems.
Analog measurement is done with a fast & high precision 12 bit AD converter. The 18 analog
input channels are configured to measure 8 voltages, 6 temperature probes and 4 general
purpose analog inputs.
The integrated supervision system compares all measured voltages with a minimum and
maximum value and temperatures with a maximum value.
Exceeding the supervision threshold can switch off the system.
Fan speed measurement and speed control of up to 6 fans is provided. The fan supply voltage
is generated on board, so no special fans with PWM input are required. Up to 3 fan groups
can be regulated individually.
If the CMLs supplied by an external power source, it is possible to switch the main system
power supply on or off with the on/off switch or via network.
All necessary functions are implemented on a small (86mm x 110mm) board. The system
connections are provided on a 2mm high density connector.
For standard backplanes (e.g. VME) specific adapters are available.
The CML/adapter combination can be inserted into Hartmann electronic standard VME, VPX,
cPCI systems, backplanes or power backplanes.
An optional alphanumeric display module can be connected to the CML. With this display all
measured values can be visualized.
