Open, modular and extremely flexible:
BL67 is a field-mounted bus I/O system where the user decides
the bus system interface, the I/O layout, type and quantity of
inputs and outputs to suit their specific requirements. Interface
gateways are also available to communicate with Profibus-DP, DeviceNet. CAN open
and Ethernet. Diagnostic
data is transferred to the higher level control-system.
The electronic modules
are capable of hot-swapping, i.e., they can be replaced during
operation. They can be removed and plugged during load-free
operation without having to disconnect the field wiring. The 24 Vdc
field supply is either provided via the gateway or the power feeding
Signal I/O in any order:
I/O modules can be combined in any order to suit your
application, whether analogue or digital, irrespective of the
fieldbus used. So the I/O layout suits your preference. You can have
your I/O on a machine-by-machine basis mixing the I/O the way you
want, or say keeping digital signal together etc., whatever you
like. You only have to buy the exact number of channels you want,
making BL67 a really cost- effective solution.
Power Supply Modules can also be
installed at any point within the BL67 station. They provide an
isolated field voltage to all modules mounted to their right. Power
feeding modules can also be used to create various potential groups.
The number of BL67 modules, which can be powered via the internal
module bus, depends on the nominal current rating of the individual
modules on the module bus.
Gateways are the link between the fieldbus system and the I/O
modules. They control the entire data communication. The BL67 I/O
system provides gateways for all major field-buses.
The modules communicate with the gateway via an internal bus.
Based on this concept, the system is open to future bus
