Analog Input Data
Run Mode
STANDARD Indicates whether consumed data is actively being updated by a device that is in one of these
states:
• Run mode: 1 Idle State: 0
Connection Faulted
STANDARD Indicates the validity of the safety connection between the safety producer and the safety
consumer.
• Valid: 0 Faulted: 1

Individual Tachometer Overfrequency
SAFETY When the input is configured for Tachometer mode, this data indicates an overfrequency
condition; that is, when pulses are faster than 1000 Hz.
Normal: 1 Fault: 0
Individual Tachometer Under-frequency
SAFETY When the input is configured for Tachometer mode, this data indicates a under-frequency
condition; that is, when pulses are slower than 1 Hz.
Normal: 1 Fault: 0
Individual Tachometer Dual Low
SAFETY Indicates that both channels are low when the input is configured for Tachometer mode.
Normal: 1 Fault: 0
Input Power
STANDARD Indicates that input power over- or under-range.
Normal: 1 Fault: 0
Analog Output Data Reset Tachometer
SAFETY Resets a latched overfrequency condition and enables the module to begin calculating frequency
again.
• No reset: 0 Reset: 1
Data Description
IMPORTANT In the previous table, ‘SAFETY’ denotes information the controller can use in
safety-related functions. ‘STANDARD’ denotes additional information that
must not be directly used for safety functions.
ATTENTION: Do not rely on data readback to detect faults. You must monitor
status bits to detect faults.
