Table 3.26 Modbus/SNMP/BACnet/Telnet Master Options
Option Description
Master Poll Interval
This is the amount of time between when a response is received from a Slave
and when the RIM-1000 asks for the next register. This interval is adjustable from
250 to 2000ms.
The interval is active only when the Serial Protocol is set to a Modbus Master
option.
The interval effects the overall scan rate. If the RIM-1000 is configured to read 60
Modbus variables and the poll interval is set to 1000ms (1second), each Modbus
variable will be read approximately once per minute.
Default: 250 mS
Master Retry
Attempts
This value determines how many times the RIM-1000 will request the same regis-
ter when there is no response from the Slave before moving on to read the next
register. This value is adjustable from 1 to 99 seconds.
Default: 1 second
Enable Virtual Slot
#1-4
The number of available virtual slots varies from 1 to 4 depending
on the RIM-1000’s physical configuration.
Virtual slots can only be created if the slot is not occupied by a
physical card. These virtual points can be used in conjunction with
Modbus/SNMP registers to allow individual alarming, notification
and relay activation per Modbus register.
BCM Zero Amp
Level Alarm
Determines if the branch circuit current is zero (CB open or tripped). It is active
when Serial Protocol is set to “Modbus Master BCM - 4 Units” or “Modbus
Master BCM - 16 Units.” This applies to all branch circuits in all the BCMs. Each
branch circuit has a “Zero Amp” Enable to enable or disable the zero amp alarm.
This setting is adjustable from 0 to 1 Amp.
BCM Status Display Displays the how the BCM status is displayed (i.e, left/right or vertical).
