The MX Active Gauge EthernetIP Gateway (sometimes also called an EthernetIP vacuum controller, EthernetIP vacuum control unit, or EthernetIP vacuum pressure controller) is the first and only solution designed to provide an EthernetIP connection between Televac® active vacuum gauges and Rockwell Automation® Allen-Bradley® PLCs. An increasingly popular industrial network communication standard, EthernetIP communication offers users faster and more reliable vacuum measurements and eliminates the need for additional analog-to-digital converters or other vacuum controllers and vacuum pressure controllers.

EthernetIP Vacuum Controller Gateway Compatible Active Vacuum Gauges

This EthernetIP vacuum control unit supports an easily configurable network of up to (4) Televac® active vacuum gauges and (1) capacitance diaphragm vacuum gauge (CDG) through EthernetIP communications. Multiple gateways can also be daisy-chained together for additional vacuum gauge connections (made possible by dual EthernetIP ports on the back of the unit). The gateway allows users to interface directly with supported PLCs and PCs, including the ability to read vacuum measurements and change vacuum gauge settings from a convenient, remote location without complicated conversion tools. In addition to Televac vacuum gauges, the gateway supports CDGs from MKS, Inficon, Leybold, Brooks, and Setra. 24 V DC and ±15 V DC with D-sub 15 (DB15) and D-sub 9 (DB9) connectors are supported.

The RJ45 connectors labeled P1 and P2 are the EthernetIP connections that will run to the PLC or PC. The RJ45 connectors labeled 1 through 4 are the active gauge inputs. These will run through Cat5e Ethernet cables and through an adapter to attach to the active gauges in the network. All active gauges must be set to separate RS-485 addresses 1 through 4 and baud rate 38400 to communicate with the gateway. The RJ45 connector labeled CDG will connect to the CDG in the network if one is available. The CDG must be turned on through the appropriate parameter in the ADI table.

The power input connector accepts a +24 V DC and GND connection, as well as an optional ±15 V DC input to run to the attached CDG if required. Regardless of the alternate supply, the gateway and attached active gauges require the +24 V DC input to be connected in order to operate. The pushbutton labeled BTLD is to be pressed while powering the gateway to send the unit into bootload mode for the ability to easily update the firmware, and the update occurs over the USB connection.

Using the Gateway for Heat Treat and Vacuum Furnace Applications

This vacuum controller gateway is particularly useful for heat treat and vacuum furnace applications where a single gateway can eliminate the need for up to (5) analog-to-digital converter (ADC) input channels while simultaneously reducing any latency from analog-to-digital conversions (causing a mismatch between the vacuum gauge display and the furnace human-machine-interface or HMI). The EthernetIP vacuum controller gateway also gives the end user the ability to calibrate their vacuum gauges from their HMI by interfacing digitally with the vacuum controller gateway. This means no more climbing on top of your furnace to do vacuum measurement comparisons! The ability to change settings and calibrate digitally is due to the unique design of the vacuum controller gateway, where all communication with Televac® vacuum gauges is done digitally (via RS-485).

More Information and Similar Products

Essentially you can think of the EthernetIP vacuum pressure controller gateway as a fancy RS-485 to EthernetIP converter. The exception to this is the CDG input, which takes the 0 to 10 V DC analog output of the CDG and converts it to a digital value (using an analog-to-digital converter) which can then be read over EthernetIP.
