Trusted TM TMR Module T8160
Issue 13 May 13 PD-T8160 32
CONFIGURATION
PHYSICAL MODULE
RACK 1: 16 BOOLEAN inputs Input states of the module as identified by the OEM parameters.
RACK 2: 1 ANALOGUE input Channel Faults (1 bit per channel) for the module.
0 - channel ok, 1 - channel fault
RACK 3: 1 BOOLEAN input Input reflecting the board status of the module specified.
FALSE - board ok, TRUE – board fault
Notes:
1. All parameters must be supplied, even for virtual boards.
2. Trusted TM chassis and slot numbers start at 1, Regent+Plus I/O chassis and slot numbers
start at 1.
3. The single analogue input channel returned provides the T7411F channel status in packed
notation. Channel 1 status will be in bit zero. Channel 16 status will be bit 15.
4. The single BOOLEAN input channel returned provides the T7411F board status.
EXTRA INFORMATION
Entering the Threshold data:
At present the threshold values have to be entered as a count between 0 and 255, (8bit word), e.g. on
a -5VDC to 32 VDC system:
COUNTS = (( VOLTAGE + 5 ) / 37) * 255
16 V would be represented by:
(16+5)/37 = 0.567.
0.567 * 255 = 145 counts
0VDC would be represented by:
(0+5)/37 = 0.135
0.135 * 255 = 34 counts
