Modbus Router/B
A-MBR/B
The Modbus® Router/B provides intelligent data routing between Logix controllers/PLCs and Modbus devices via Modbus RTU (RS232 / RS485) or Modbus TCP. The Router can operate as either a Modbus Client (Scheduled Mode) or Modbus Server (Reactive Mode).
Communications with a Logix controller (e.g., ControlLogix® or CompactLogix™) can be achieved via EtherNet/IP™ or USB. Direct-to-Tag technology enables the router to exchange data directly with Logix Tags, thus requiring no Logix programming.
When using USB, a redundant system can be configured using one Router for each Logix controller. Only the Router connected to the Primary Logix controller will respond to the Modbus TCP requests.
The Router also supports the MicroLogix™ and SLC™500 platforms.
The Router hosts two Ethernet ports which can be configured in a Device Level Ring or Linear topology.

Features and Benefits
- The MBR/B can operate as a Modbus Client or Modbus Server.
- Modbus Client mode can communicate with up to 100 Modbus Servers.
- Supports Modbus passthrough messaging.
- Modbus Server mode supports full Modbus data range.
- Modbus Server mode supports emulating multiple Modbus nodes.
- Configurable Modbus TCP Port numbers.
- Supports EtherNet/IP Target and Originator modes:
- EtherNet/IP Target (Class 1 connection)
- EtherNet/IP Originator (Class 1 connection with up to 10 EtherNet/IP devices and Explicit Messaging, including Direct-To-Tag Logix tag access, with up to 10 EtherNet/IP devices)
- Supports CIP USB interface for Logix controllers.
- EtherNet/IP Class 1 target connections support 2kbyte input and 2kbyte output data to Logix input and output assemblies.
- Supports Modbus media conversion allowing for a transparent link from one media to another (e.g., Modbus TCP to Modbus RTU232).
- Slate provides a Modbus packet capture utility for better diagnosis.
- Dual Ethernet ports which support Device-Level-Ring (DLR).
- Network Time Protocol (NTP) supported for external time synchronization.
- Small form factor – DIN rail mounted.
