Trusted TM TMR Module T8160
Issue 13 May 13 PD-T8160 21
4.4. I/O Complex Equipment ‘TX7401’
Description: T7401 DC Digital Input Module, 24V dc. The Digital Input Module interfaces 16
discrete field devices into a triplicated I/O Safetybus. Field power for the input is
arranged in two 8-point groups. The 24V dc digital input module provides 16 sinking
input circuits capable of sensing digital inputs that switch field power ranging from
14V dc to 32V dc. This board definition is for modules used in a triplicated
configuration.

CONFIGURATION
PHYSICAL
3 (boards) X 16 digital input channels, Boolean, triplex.
LOGICAL
RACK 1: 16 BOOLEAN inputs Voted data for input channels
TRUE – channel high, FALSE - channel low
RACK 2: 3 BOOLEAN inputs Input reflecting the board status of the module specified.
First channel is board status for board 1.
Second channel is board status for board 2.
Third channel is board status for board 3.
FALSE – board ok, TRUE - board fault.
RACK 3: 16 BOOLEAN inputs Data reflecting the discrepancy status of the last vote performed for the
channel
Channel 1 contains data for module channel 1, Channel 16 contains
data for module channel 16.
TRUE - A discrepancy has occurred, FALSE - All channels agree. The
variable is not latched.
Note: The value will be TRUE if any of the channels is different to the others. i.e. a discrepancy is
present. The discrepancy value is not latched or filtered in any way.
PROGRAMMING NOTE
ALL channels for both real and virtual boards MUST have a variable attached regardless. Assign the
same CHASSIS/SLOT user parameter values to each board as allocated.
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.
