HILOALB Example
In the following example, the HILOALB instruction is used to monitor a binary value that is
in V2000. If the value in V2000 meets/exceeds the high limit of the binary value in V2011,
C101 will turn on. If the value continues to increase to meet/exceed the high-high limit value
in V2010, C100 will turn on. Both bits would be on in this case. The high and high-high
limits and alarms can be set to the same V-memory location/value if one “high” limit or alarm
is desired to be used.
If the value in V2000 meets or falls below the low limit of the binary value in V2012, C102
will turn on. If the value continues to decrease to meet or fall below the low-low limit in
V2013, C103 will turn on. Both bits would be on in this case. The low and low-low limits
and alarms can be set to the same V-memory location/value if one “low” limit or alarm is
desired to be used.
