Hi/Low Alarm - Binary (HILOALB) (IB-401)
Hi/Low Alarm - Binary monitors a binary (decimal) V-memory location and sets four
possible alarm states, High-High, High, Low, and Low-Low whenever the IBox has power
flow. You enter the alarm thresholds as constant (K) decimal values (K0-K65535) and/or
binary (decimal) V-memory locations.
You must ensure that threshold limits are valid, that is HH >= H > L >= LL. Note that when
the High-High or Low-Low alarm condition is true, that the High and Low alarms will also
be set, respectively. This means you may use the same threshold limit and same alarm bit for
the High-High and the High alarms in case you only need one “High” alarm. Also note that
the boundary conditions are inclusive. That is, if the Low boundary is K50, and the Low-Low
boundary is K10, and if the Monitoring Value equals 10, then the Low Alarm AND the
Low-Low alarm will both be ON. If there is no power flow to the IBox, then all alarm bits will
be turned off regardless of the value of the Monitoring Value parameter.
HILOALB Parameters
• Monitoring Value (Binary): specifies the
V-memory location of the Binary value to be
monitored
• High-High Limit: V-memory location or
constant specifies the High-High alarm limit
• High-High Alarm: On when the High-High
limit is reached
• High Limit: V-memory location or constant
specifies the High alarm limit
• High Alarm: On when the High limit is
reached
• Low Limit: V-memory location or constant
specifies the Low alarm limit
• Low Alarm: On when the Low limit is reached
• Low-Low Limit: V-memory location or constant specifies the Low-Low alarm limit
• Low-Low Alarm: On when the Low-Low limit is reached
