Advanced Diagnostics
Hardware Installation
4.4.1 KT-MB-GT2AD.FF
FDS/OPC Integration
Each diagnostic bus carries its own volt-free contact lines. These lines are connected on the
motherboard to the following terminals:
• Channel 1: Alarm output for diagnostic bus channel 1
• Channel 2: Alarm output for diagnostic bus channel 2
The common alarm output terminals are not used. The 2 diagnostic bus channels can be con-
nected separately to PCS inputs or can be wired in series.
FOUNDATION Fieldbus Integration
If the FOUNDATION Fieldbus integration is used the volt-free contacts can be used the same
way as for the FDS/OPC integration. Beside this, the common alarm output can be configured
to react to the FOUNDATION Fieldbus field diagnostic parameters. For more information, see
chapter 7. Since the DGW-FF reads the alarm status of all connected ADMs using the
8 communication lines of the diagnostic bus and sets the FF field diagnostic according to the
status of the ADMs, the common alarm output can reflect the alarm status of the connected
ADMs.
4.4.2 KT-MB-GT2AD.FF.IO
FDS/OPC Integration
The diagnostic gateway functionality allows configuring the outputs of the I/O motherboard
according to the status of the field diagnostic parameters. This status can also be influenced by
the binary inputs of the diagnostic bus alarm contacts.
Typically, binary input 5 and binary input 6 are configured to create a field diagnostic alarm and
the common alarm output to be activated if any field diagnostic alarm becomes active.
FOUNDATION Fieldbus Integration
If the FOUNDATION Fieldbus integration is used, the volt-free contacts can be used the same
way as for the FDS/OPC integration. Since the DGW-FF reads the alarm status of all connected
ADMs using the communication lines of the diagnostic bus and sets the FOUNDATION Field-
bus field diagnostic according to the status of the ADMs, it is not required to read the ADM sta-
tus based on binary inputs. In this case, the binary input 5 and binary input 6 are not required to
be connected to the I/O motherboard and can be used independently for other I/O purposes.
Note
The volt-free contact lines of the diagnostic bus of the ADM modules can be connected directly
to a PCS input. The lines are not required to be connected to the motherboard of the diagnostic
gateway. If this is applicable for an installation, binary input 5 and binary input 6 can be used
independently for other I/O purposes.
