Cabinet I/O
Besides ADM access functionality, the diagnostic gateway KT-MB-GT2AD.FF.IO provides I/O
functions mainly for cabinet management applications. The following inputs and outputs are
available:
•
Inputs:
•
•
•
•
•
•
Outputs:
•
•
•
Integrated on/off controllers allow local control functionality inside the diagnostic gateway, e.g.,
for thermostat controls.
This functionality is provided for the FF integration, as well as for the FDS/OPC integration. The
main difference between these 2 types of is the possibility to interact with FF function blocks
where the FDS/OPC integration does only support local control. Access to the I/O functionality
is provided in the following way:
•
FF Integration
The I/O functionality is provided as an FF transducer block. Several channels for the func-
tion blocks allow to access the input and outputs. See chapter 7.5
•
FDS/OPC Integration
The FDS port DTM provides an online and offline parameterization user interface for this
functionality. This port behaves like an FF transducer block, i.e., the block must be set to
"OOS" before any parameter can be changed and must be switch back to auto for opera-
tion. Handling of the resource block mode is not required.
The I/O functionality is not integrated with the OPC server. The local control functionality
can be used as described in this chapter and alarms to a PCS can be sent using the com-
mon alarm output.
The common alarm output of the I/O functionality is also provided on the KT-MB-GT2AD.FF
and can be used for a volt-free contact integration of the ADM functionality in FF integration
mode. See chapter 4.4

Field Diagnostics
The inputs of the IO_TB can be integrated with field diagnostics in either of the following ways:
•
Map a binary input to field diagnostics: When the corresponding bit in FD binary * map is
set, a binary input value of "1" triggers the field diagnostics condition.
•
Compare analog inputs values against limits: All analog inputs have Hi and Lo Mainte-
nance Required and Out of Specification limit settings. Whenever the input value is out-
side the selected limits, the field diagnostics condition is triggered.
•
Input lead break/short circuit detection is mapped to field diagnostics. Whenever a lead
break/short circuit condition is detected, the corresponding field diagnostics condition is
triggered.
136
2 binary inputs that can also be used as frequency inputs.
4 binary inputs (NAMUR sensors)
2 temperature inputs for use with PT100 sensors that can also be used as binary
inputs.
1 temperature sensor integrated on the motherboard.
1 humidity sensor integrated on the motherboard.
2 relay outputs.
1 common alarm output, a volt-free contact for alarm loops; off=closed, on=open.
1 buzzer.
