Introduction

INTRODUCTION
The MB-700 is a powerful multifunction module from LC700 family that can be used isolated or
integrated to the SYSTEM302. The module can perform multi function in MODBUS protocol like
gateway MODBUS TCP/IP and MODBUS RTU, MODBUS data concentrator and Peer-to-Peer
communication between MODBUS slave devices.
These are some of MB-700 characteristics:
•Tight integration with intelligent devices and software from multiple manufacturers due to use of
open standards as OPC Server and Modbus TCP/IP and RTU;
•Totally integrated unit having the following functions: interface, gateway, linking device, bridge
and MODBUS data concentrator;
•As Gateway Modbus, the MB-700 can work in both directions: as Gateway TCP/IP to Serial or
Serial to TCP;
•As Data Concentrator the module can concentrate the data from the slaves in the serial and
provide the data to TCP/IP via OPC or MODBUS TCP/IP;
•As Peer-to-Peer can exchange MODBUS data between slaves connected in the TCP/IP, Serial
or both Medias; and
•Full redundancy and fault isolation for high safety and uninterrupted operation.

OVERVIEW
This manual presents instructions of how to install the MB-700.
The MB-700 is a microprocessor module. It has Ethernet, EIA-232/EIA-485 ports plus a
synchronism port that might be used for redundancy. The MB-700 uses a power supply PS-AC-R.
The MB-700 system consists of a CPU module plus this power supply module.

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.

Overview
1.3
System Integration
Advanced communication characteristics built in the MB-700 grant the system high integration:
- Ethernet Port;
- Modbus TCP/IP;
- Serial EIA-232 / EIA-485 Ports;
- Modbus RTU; and
- Supports up to 31 slaves connected to the EIA-485 bus.
Power Supply – PS-AC-R
This module is the power supply for the MB-700 and LC700 system. It supplies 5V necessary to the
IMB. This module has functions of diagnose and dedicated LEDs that indicate normal operation in
failure conditions what makes possible troubles to be easily detected, especially in systems with
several units. It is easy to check a power supply module with defects in a panel with several
modules. It is possible to replace the fuse (located on the input with external access) without
needing to remove the source module or disconnect any wire. The output is protected against short
circuit and it is not damaged even in lasting short circuits.
Processor Module – MB-700
Based in a 32-bit RISC processor and firmware stored in a Flash memory, this module handles
communication and control tasks.
- 1 Ethernet Port @ 10Mbps
- 1 SYNC Port @ 31,25Kbps
- 1 EIA-232/EIA-485 Port @ 9,6 Kbps – 115,2 Kbps
- CPU Clock @ 25MHz, 2MB NVRAM
Open Protocols
Ethernet
Implements the Smar Ethernet protocols (SE) and MODBUS based on TCP/IP and may coexist with
other Ethernet protocols.
Modbus RTU: EIA-232 and EIA-485
Using these ports, the MODBUS protocol connects data from a MODBUS network with the local
area network. These ports may be connected to a device network (EIA-485) or connected to
controllers through a modem or a radio link. Supports up to 31 slaves connected in each serial port
using the EIA-485 standard.
Configuration
MB-700 is completely configured using the configuration tool (for example, SYSCON) through
function blocks available in the FOUNDATION FieldbusTM Standard.
Supervision
The use of these technologies like OPC (OLE for Process Control) makes the MB-700 a flexible
TCP-IP/MODBUS interface. The OPC Server allows the MB-700 to be connected to any supervision
package. The only requirement is that there is an OPC client to the package, so user can connect
the MB-700 with the best supervision interfaces available.
