Module Status (Ai_00) - Spectrum Controls Micro 800 User Manual

3.5.4 Module Status (AI_00)

The 2085sc-OF8 module status bit definitions are listed below:
Bit Name Description
General Status <channel>
General status bit. If a bit is set (1) then there is an error associated with that
7:0 S<n>
channel (check Status bits for the indicated channel).
Bit 0 = Channel 0, Bit 1 = Channel 1 etc.
Field Power Fault
When set, 24 VDC field power is over-voltage or under-voltage.
The user-specified voltage range is 20.4 V ~ 26.4 V. The module can operate
outside of this range but will disable outputs when the voltage is outside of
maximum and minimum values. There is no guarantee that outputs will perform
as specified when outside the user-specified range.
8 FP
When the Field Power drops from normal operating range to a value below 18.7
volts, outputs are disabled and this flag set. There is no guarantee at which
voltage below 18.7 will set this bit.
When Field Power is applied, the FP bit is cleared, and outputs enabled when
the voltage is greater than 19.9 V (±0 V) and less than 27.8 V (±1 V).
The FP bit is set, and outputs disabled when Field Power is greater than 28.1 V
(±1 V).
Invalid Cal Data
The stored calibration data is corrupt or invalid.
9 CAL
The module must be factory calibrated before it will operate normally.
15:10 Not Used Bits marked as Not Used are set to 0.
