VME/VXS Crate control Applications

Hardware

We will be using Wiener UEP6000/PL500 VME crates and UEP6023/PL500 VXS crates. We need to control and monitor the power supply/fan base of these crates. The variables include:

• Power supply status
• Fan tray status
• Fan speed
• Temperature sensors
• Various voltage and current sensors on the crate

These crate have three interface which we could use to communicate remotely:

• CAN-bus
• Serial RS-232
• Ethernet SNMP

Our choice would be SNMP since it will not require us to create any new piece of infrastructure to control crates.
