Input Modules
These features are available on input modules.
• Latching alarms, when set, latch low- and high-alarm status information.
Available alarms include:
–
Low.
– Low Low.
– High.
– High High.
• Disable alarms - disables all channel alarms and faults so they are not
reported in the channel status field. Four different alarms are available.
• Settable update rate update rate determines how often an input channel is
scanned.
• Notch filter is selectable for both inputs (50, 60, 250, and
500 Hz).
• Digital filter sets a time constant.
Output Modules
These are features available on output modules.
• Latching alarms, when set, latch low and high clamp alarm status
information.
