SNMP
Use SNMP and a Network Management System NMS.
The enterprise number is 11072 (IOTEC AB).
The RMC supports the system group in the MIB-II
Objects:
sysDescr
sysUpTime
The private MIB presently contains the following objects:
rmcTemp-1
Integer value in degrees Celcius of temperature 1.
rmcTemp-2
Integer value in degrees Celcius of temperature 2.
rmcTemp-3
Integer value in degrees Celcius of temperature 3.
rmcAnalog-4
Value 0 - 100% of the current signal 4 - 20 mA at analog input 4.
rmcAlarmsExist
ALL-OK(0) or ALARMS-EXISTS(1). This can be seen as the sum of all alarms. You
could have your management system read this object periodically to see if everything is
ok and if not, check the main web page for a total overview.
rmcAlarm-1 -- rmcAlarm-8
Eight objects, one for each alarm channel, giving OK(0) or ALARM(1).
rmcOut-1 -- rmcOut-3
Status for the three power outputs. Can also be set on or off by the NMS.
rmcTrapMessage
When an alarm trap is sent, this object holds the alarm text string which are appended to
the trap. In the MIB-file are eight traps defined. The MIB-file can be downloaded from the
RMC-support homepage.
Supervision with the RMC using SNMP can be configured in several ways. A simple
configuration could be to set up the eight function channels and limit values in the RMC
and have your network management system read the single object rmcAlarmsExist
periodically to see if everything is ok. Set up your NMS to give an alarm event if rmcA-
larmsExist returns 1, indicating that something is abnormal. When this happens, just
browse the main web page in the RMC for a total overview and with its event list in plain
English. You could also read the analogue values separately and define the limit values
in your NMS. This way you can have all eight digital inputs for alarms and thus get a to-
tal of 12 monitored objects.
Maybe the most common method is to use the traps, one for each alarm channel.
