Foxboro P0800DV Fieldbus Extension Cable
Fieldbus Communication
The fieldbus communication module or control processor is connected to the
redundant 2 Mbps modular fieldbus used by the FBM.
The Compact FBM242 accepts communications from either path (A or B) of
the redundant 2 Mbps fieldbus
– if one of the paths fails or is not in operation, the FBM will not accept
communications from the other path.
If one of the paths fails or is shut down at the system level, the module will
continue to communicate over the active path.
Current Limit
Field power supplies used for contacts or solid state switches are current limited.
Terminal Assembly (TA)
Field I/O signals are connected to the FBM subsystem via DIN rail mounted TAs.
Visual indicators
Light-emitting diodes (LEDs) on the front of the module provide a visual indication
of the module’s operating status and the discrete status of each output point.
Features
Key features of the 200 Series Base Plate are listed below:
for FBM-enabled baseplates:
– 2. 4. and 8 module positions combined with vertical and horizontal mounting
– Field connectable I/O termination assemblies, redundant adapters, and modules
Identifiers for each module
– DIP switches for identification of specific module backplanes
– Additional 200 series baseboards can be added without removing the
system from service (redundant bus required)
supports FCP280/FCP270. FDC280. and FCM100Et baseboards:
– Connection for optional GPS time strobe.
All non-FDC280 module time strobe connections require a splitter/splitter.
direct connections are supported on the FDC280 baseboard.
All baseboards are supported except the FDC280 baseboard (RH101KF):
– Connection to 2 Mbps modular fieldbus for standard fieldbus modules or 268 Kbps
fieldbus for 100 series FBMs
– Splitter/terminal modules for A/B fieldbuses
– Backwards compatible with existing I/O subsystems, allowing for future expansion
No additional interface hardware required
Primary and secondary 24 VDC power supplies and communication connections
Dedicated keying position for individual CP-type modules (e.g. FCP280. FDC280
or FCM/FBM),
depending on the substrate type
Passive backplane for increased system reliability.
