Bit triggered alarm messages are defined by a bit offset (Value/Bit
field) from the Trigger Tag address. For example, if the Trigger Tag
address is defined as B3:1/0, alarm messages can be triggered from
addresses B3:1/1 and B3:1/2.
When the motor speed reaches 1200 rpm, the logic controller sets bit
B3:1/2, triggering an alarm condition. The message MOTOR SPEED
HIGH! will appear in the alarm banner.
When the motor speed reaches 1500 rpm, the logic controller sets bit
B3:1/1, triggering an alarm condition. The message MOTOR SPEED
HIGH HIGH! will appear in the alarm banner.
