Write and read individual set voltages, “guru” access needed to write!

192.168.2.25 outputVoltage.u101 F 200
WIENER-CRATE-MIB::outputVoltage.u101 = Opaque: Float: 200.000000 V
Note the “F” before the 200, this indicates that the value is a floating point number. This value can be read
back via:
snmpget -v 2c -m +WIENER-CRATE-MIB -c public 192.168.2.25 outputVoltage.u101
WIENER-CRATE-MIB::outputVoltage.u101 = Opaque: Float: 200.000000 V
Turning Channels ON/OFF - The individual channels of an MPOD system low or high voltage
module can be turned on or off using the snmpset command. To turn on channel Ux:
snmpset -Oqv -v 2c -M $path -m +WIENER-CRATE-MIB -c guru $ip outputSwitch.index i
1
The same channel can be turned off with:
snmpset -Oqv -v 2c -M $path -m +WIENER-CRATE-MIB -c guru $ip outputSwitch.index i
0
The
outputSwitch
can also be used for emergency-off and to reset error flags. The matching values are:
{off(0), on(1), resetEmergencyOff(2), setEmergencyOff(3), clearEvents(10)}

MPOD low and high voltage modules have programmable voltage ramp speeds. The WIENER low voltage
modules allow different ramp up and down values for each channel whereas for ISEG modules with
common ramp the channel-ID can be any channel of the module! For write access “guru” is needed:
snmpset -Oqv -v 2c -M $path -m +WIENER-CRATE-MIB -c guru $ip outputVoltageRiseRate.index
F value
Example:
snmpset -v 2c -m +WIENER-CRATE-MIB -c guru 192.168.2.25 outputVoltageRiseRate.u101 F 10
WIENER-CRATE-MIB::outputVoltageRiseRate.u101 = Opaque: Float: 10.000000 V/s
snmpget -v 2c -m +WIENER-CRATE-MIB -c public 192.168.2.25 outputVoltageRiseRate.u101
WIENER-CRATE-MIB::outputVoltageRiseRate.u101 = Opaque: Float: 10.000000 V/s
To access multiple units the
groupsSwitch
function provides access to all modules in the MPOD
crate (index 0), all ISEG HV modules (index 64), or to all WIENER low voltage modules (index
128). In addition groups can be defined for low voltage modules.
