Metering Chapter 4
These are the semantics:
• If Demand_Broadcast_Mode_Select is set to master, then a Demand
Source value of 0…2 selects the EOI source that is used to trigger the
demand-sync master broadcast.
• If Demand_Broadcast_Mode_Select is set to slave, then a Demand Source
value of 0…3 selects the EOI source.
Demand_Period_Length (Minutes)
Specifies the desired period for demand calculations. These are the values:
0 = See semantics
1…99 = Length of time of each demand period in minutes
These are the semantics:
• When set to 0 there is no projected demand calculations.
• If the internal timer is selected, a setting of 0 turns the demand function
off.
Number_Demand_Periods
Specifies the number of demand periods to average for demand measurement.
These are the values:
1 = Used for fixed demand period
2…15 = Used for sliding window demand period
Forced_Demand_Sync_Delay
When configured for an external demand source, this parameter defines how
long the unit waits for the expected control input (for example, EOI pulse or
network demand broadcast), before it starts a new demand period. If this occurs
an entry is made in the Event Log. These are the values:
0 = Wait forever
1…900 = Wait this many seconds before starting a new demand period
Network demand synchronization is available on units connected to an Ethernet
network. Network-demand synchronization parameters are found in the
Communications_Native tab under Configuration tab.
