MB-700 – User’s Manual
1.2
Main Characteristics
MB-700 has a double function: it is both a bridge between Ethernet and Modbus networks and a
data concentrator device.
The
MB-700 has a modular concept and may be put in panels inside a control room or in sealed
boxes in the field. It is indicated to remote applications avoiding that user needs to walk to the place
where the process is located to configure the MODBUS device. User only needs to connect his
workstation or Human Machine Interface (HMI) to the network and configures the logic controllers
through the network.
MB-700 handles the communication and conversion between protocols. It may
be set to act as a data concentrator, collecting data from field devices connected to the MODBUS
slaves. Its monitoring system or supervision system may access all this collected data directly on
the
MB-700 memory, instead of accessing these data directly from Field.
It is a multi function module mounted in a backplane connected in a DIN rail where it is also
connected a PS-AC-R power supply module. Modularity is the key for flexibility of the
MB-700 .
Connections of source and SYNC channel (redundancy function) are done using plug-in connectors,
making removing safe and easy. Connectors have an advantage, they cannot be connected in a
wrong way, avoiding that high voltages are applied to a low voltage terminal. The power supply
module has diagnostic LEDs to indicate normal operation or failure, what helps to solve troubles and
to diagnose, especially in a system with several units. It is possible to remove the fuse (accessible
externally located in the input) without the necessity to remove a source module or disconnect any
wire.
It is important to notice:
- One Backplane is required for each 4 modules;
- One flat cable is required to connect Backplanes; and
-
MB-700 uses the DFI OLE Server. The license to the DFI OLE Server is available in different
levels with different capacities for supervision of function blocks.
