DH485 Router

DH485 Router

A-DH485R/B

The A-DH485R/B DH485 Router provides intelligent data routing between EtherNet/IP™ and DH485, simplifying the migration from MicroLogix and SLC systems with DH485 communications to EtherNet/IP based ControlLogix or CompactLogix platforms.

The module can be used for remote programming of a SLC5/03 controller via Ethernet.

The DH485 Router’s AIC Mode provides direct conversion between RS485 and RS232, an ideal replacement for Rockwell’s 1761-NET-AIC module.Alternatively, the module makes use of the DH485 destination Node Address, (and Data File address in certain modes), to determine the target Logix controller. The mapping table, which can be configured in minutes, supports connections up to 8 Logix controllers.

In Transparent PCCC mode, the user will be able to program and connect to SLC5/03 PLCs.

The module can operate in both Logix “owned” and standalone mode. With a Logix connection, the input and output assemblies will provide additional diagnostics information in the Logix controller environment.The module’s RS485 port uses a terminal block for convenient installation.A built-in webserver provides detailed diagnostics of system configuration and operation, including the display of received DH485 communication packets, without the need for any additional software.
