B-178 Parameters
1503-UM054C-EN-P – June 2013
Correct Termination Resistor Installed in MC System
[Correct MC Termination Resistor]
Parameter Number: 340,280,220,160,99.
Access rule: Get
Data Type: BOOL
Object Mapping: 0x384-1-63
Group: Diagnostics
Units: -
Minimum Value: 0 = Not Present
Maximum Value: 1 = Present
Default Value: 0
This parameter allows the user to view the status of the MC
Termination Resistor installation. If this bit is ‘0’, then the correct
MC Termination Resistor is not installed in the MC system. If this
bit is ‘1’, then the correct MC Termination Resistor is installed in the
MC system. For the MC system to have the correct Termination
Resistor installed, only the last MC unit in the MC system must have
its resistor turned on.
Termination Resistor Installed in IB2
[IB2 Termination Resistor]
Parameter Number: 341,281,221,161,_.
Access rule: Get
Data Type: BOOL
Object Mapping: 0x384-2-63
Group: Diagnostics
Units: -
Minimum Value: 0 = Not Present
Maximum Value: 1 = Present
Default Value: 0
This parameter allows the user to view the status of the MC
Termination Resistor installation on IB2. If this bit is ‘0’, then the
MC Termination Resistor is not installed on the IB2 unit. If this bit
is ‘1’, then the MC Termination Resistor is installed on the IB2 unit.
For the MC system to have the correct Termination Resistor installed,
only the last MC unit in the MC system must have its resistor turned
on.
