Ethernet connection via the serial port on a PLC

GE Fanuc Automation introduces the VersaMax SE, a versatile, cost-effective programmable logic controller accessory that enables Ethernet connection via the serial port on a controller.

GE Fanuc Automation introduces the VersaMax SE, a versatile, cost-effective programmable logic controller accessory that enables Ethernet connection via the serial port on a controller.

The new VersaMax SE complements GE Fanuc's growing line of controllers, including the recently released VersaMax Nano and VersaMax Micro controllers.

The VersaMax SE allows users to solicit and send information, upload/download programs, and monitor and control devices over Ethernet.

"The VersaMax SE now brings Ethernet down to the lowest control point on the plant floor," said Uwe Henze, manger product marketing at GE Fanuc.

"We are convinced that Ethernet will be the network of choice at all levels of industrial control, and we will continue to build our hardware, software and support services programs with enterprise-wide communication and Ethernet in mind." Measuring 36mm wide by 60mm deep by 90mm high, the VersaMax SE quickly connects serial devices on the factory floor to an Ethernet network.

As with the VersaMax Micro and Nano controllers, the VersaMax SE accessory features the convenience of DIN rail mounting, allowing users to install the product onto a DIN rail rack and attach the serial interface of the device to the VersaMax SE.

The VersaMax SE includes screw terminal blocks that support RS-232 or RS-485 serial interfaces or an RJ45 connector supporting the RS-232 standard for serial device attachment.

Serial speeds of up to 38.4 Kbps are supported along with DSR and DTR modem controls.

In terms of networking, the VersaMax SE supports an RJ45 10BASE-T interface at 10 Mbps that allows convenient Ethernet network access.

Once connected to the network, the VersaMax SE allows users to choose from a wide range of IP protocols.

The VersaMax SE is pre-configured with SNP/SNPX (Series Ninety Protocol) on the serial side and SRTP (GE Fanuc Ethernet) on the Ethernet side.

Additional IP protocols supported are Modbus Ethernet, UDP, TCP, Telnet and limited support for Ethernet Global Data (EGD).

On the serial side, additional protocols supported are Modbus RTU and ASCII.

The multi-protocol options of the VersaMax SE provide customisable support for PLCs, printers, bar code readers, variable frequency drives, solid-state starters, or other ASCII devices that require Ethernet connection.

Additionally, the VersaMax SE provides a wealth of management options for controlling attached serial devices.

It can be managed via Telnet or SNMP over the network and configured or managed via its serial port.

It also contains Flash ROM that allows new or customised versions of operating code to be easily downloaded from the TCP/IP host (TFTP download) or via the serial port.

GE Fanuc Automation is a leading global supplier of automation controls.

These products and services include a wide range of CNCs, motion control products, micro to high-end PLCs, monitoring and control software products, and CO2 and YAG lasers.

GE Fanuc Automation is a joint venture between GE and Fanuc Ltd and the company's European headquarters are at GE Fanuc Automation Europe in Luxembourg.
