Control, Measurement and Data Logging System

Specifications:

  • Fan control:  9 fans monitored, fan speed programmable (no PWM signal necessary)

  • Fully controlled, programmable trip thresholds (min/max voltage, max current, power, temperature)

  • Digital inputs and outputs

  • Generation and detection of VME/cPCI RESET and ACFAIL

  • ON/OFF switch, VME/cPCI RESET button and up to 5 LED’s on the front panel

  • Digital Signal Processor (DSP) for real-time processing of all measured data

  • Powered by 5V bus voltage or separate power supply

  • Ethernet connection IEEE 802.3, 10BASE-T, and IEEE 802.3u 100BASE-TX

  • www-Server integrated, full control via SNMP protocol

Features at a Glance:

  • The Control, Measurement and Data logging system (CML) is designed to add remote control and monitoring functionality to electronic systems
  • Available in 6U height for both CompactPCI and VME64x
  • Analog measurement is done with a fast and high precision 12-bit AD converter
  • The 24 Analog input channels are configured to measure 8 voltages, 8 current-proportional voltage signals, and 8 temperature probes.  If current shunt signals are not used, these inputs may be used as general purpose analog inputs
  • The integrated supervision system compares all measured voltages with a minimum and maximum value and the currents, temperatures and with a maximum value.  Exceeding the programmable supervision thresholds can switch off the system.  All supervisory items are programmable via SNMP
  • Fan speed measurement and fan speed control of up to 9 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 of 3 each can be regulated individually
  • If the fans are supplied by a separate power supply, a follow-up time can be set and the system can be cooled down after power off
  • If the CML is supplied by an external power source, it is possible to switch the main power supply on or off with the on/off switch or via the network
  • Implemented on a small form factor board (100mm x 120mm), with the system connection  provided on a 2mm high density connector

  • The CML has built-in web-server which allows the monitoring of the power supply with a standard web browser.  Any write access to the web page (such as switch ON/OFF) requires a user name and password (Default User name “private”, default password “private”)
  • SNMP Control:  SNMP is generally used to monitor and control computers and routers.  Weiner has claimed a specific part of the SNMP name space and implemented power supply specific items there.  A detailed description of the SNMP functionality can be found in the corresponding MIB file (WIENER-CRATE-MIB.txt)
