Module Data Types - 1794-IJ2, 1794-IJ2I, 1797-IJ2

The table below lists and describes module-defined data types for the 1794-IJ2, 1794-IJ2I, and the 1797-IJ2 modules. It includes information for input (as indicated by an I) and configuration (as indicated by a C) in the module Tag Type name shown on the Controller Tags window in the

Description
Fault
DINT
Binary
Used for Input Data Validation - 0 means the data is valid. If the connection to the module has been lost, or if the module has a severe hardware fault, 1s are represented in this input data type.
Ch0Frequency
INT
Decimal
Calculated value of Frequency for Channel 0. Frequency can be reported down to 1 or 1.0 Hz, depending on the Frequency Range setting. Below a 1 Hz value, 0 is reported. Below a 1.0 Hz value, 0.0 is reported. Calculated frequency depends on Minimum Sampling Time and Missing Pulse Multiplier. If input pulses are not present within the time periods allotted by these parameters, zero frequency (0 or 0.0) is reported, depending additionally on the setting of the Wire Off Fault Detection Mode. When the Frequency exceeds the module’s Max Input Frequency, the Frequency value 32,767 is reported, or- the Frequency value 3,276.7 is reported, depending on the Frequency Range data type.
When the Scaled Frequency exceeds 32,767 or 3,276.7, the Frequency value 32,767 is reported.
If a Wire Off Alarm is detected and enabled, the Frequency reported may be an Unchanged, Maximum (32,767 or 3,276.7 default or the Maximum Frequency value), or Minimum value (1 or 1.0), depending on the selection of the Wire Off Fault Alarm and the Frequency Range data type.
