ENET-710 Module  

 

 

 

 

 

Connect the LC700 and CD600Plus in your LAN (Ethernet)

The ENET-710 is a data communication module that bridges Ethernet and Serial communication networks. Designed to support MODBUS and CDBUS protocols is an ideal choice to add Ethernet connectivity to Smar LC700, DF65, CD600 and CD600Plus devices.  

The ENET-710 has 5 serial channels (1 RS-232c and 4 RS-485) to increase connectivity and speed in data stream.

With the increasing importance of networking for industrial control/automation, the ENET-710 module provides Ethernet-networked computers the ability to perform remote monitoring and control of serial MODBUS and/or CDBUS compatible industrial devices in the field.

Up to seven clients can simultaneously access the ENET-710 via Ethernet and communicate over one full-duplex RS-232C and four half-duplex RS-485 compatible serial devices. The module can be directly installed in the LC700 Rack or it can be operated in a stand-alone mode with an external +24VDC power supply.

 

 

Multi-master

When serial devices are connected to the Ethernet through the ENET-710 they can be accessed by more than one Computer, expanding in this way the traditional "one master and multiple slaves" architecture.

 

 

Communication Protocols

Fully compliant with MODBUS/TCP, the ENET-710 implements bridging to the LC700 PLC CPU serial ports or any other MODBUS/RTU compatible slave device. It is also ready for the CDBUS/TCP allowing bridging between Ethernet and the serial CDBUS protocol supported by the Smar CD600/CD600Plus Multi-Loop Controllers.

The ENET-710 supports 10/100 Mbps Ethernet and serial speeds of up to 115,200 bps depending only on limitations of the devices used.

 

 

Improve overall communication speed

The 5 serial channels allow better distribution of slave devices and significantly diminish the typical "bottle-neck" caused by multi-drop architectures. Distribute the devices the most you can between the available channels for a better performance.

 

 

Configuration Web Page:

An internal WEB server provides the user a direct configuration using a regular internet browser (Compatible with: MS Internet Explorer, Netscape, Mozilla and Mozilla Firefox).  Once connected to the ENET-710 a menu is accessed via a simple web page dedicated to configure the device.  

All five serial ports are set for desired baud rate, protocol, parity, stop bits, address range and response time-out.

Additionally, system administration settings such as the login username, password, device IP address and subnet mask are present.

Two serial port redundancy modes (parallel and ring) are available for devices with one or two serial channels.

 

 

Redundant Power Supply:

The ENET-710 supports a redundant power supply mode to provide continuous operation should the external +24VDC power source fail. For this kind of operation it is necessary to connect it at the IMB bus. If power supply redundancy is not necessary, the user can opt to drain power from the IMB or attach it to an external 24VDC supply.
