Gateways and Couplers

There is some confusion in the industry about these two terms. In general, they both provide a method for ‘joining’ two different networks. Strictly speaking, gateways provide a protocol conversion from one protocol to another.  A coupler provides a way for two networks to share information – normally by having it be a ‘slave’ on both networks and sharing information via dual-ported RAM.

Couplers are simpler and safer. There is no way to get from one network to the other when using a coupler. Gateways typically do have a way for software packages to get from one network to the other.

Please contact us and we can help you select the best Gateway or Coupler for your application and provide a quote.

PROFIBUS Gateways

Anybus PROFIBUS DP to PA gateway

Anybus Diagnostics (formerly PROCENTEC) COMBRICK can also be an invisible gateway from PROFIBUS DP to PROFIBUS PA. This is an excellent way of connecting PROFIBUS PA instruments to your main DP network.

The transparent PROFIBUS PA link/coupler enables seamless high speed integration to PROFIBUS PA. It powers the attached PA devices and fully emulates them as DP devices on the backplane. Adjusted bus parameters are not required and therefore suitable for all DCS and PLC systems, even running on 12 Mbps.

Ethernet (PROFINET or Modbus TCP or HART-IP) to HART gateway

isNet Lite Headstation

The isNet Lite is an Ethernet gateway. It supports the PROFINET, MODBUS TCP and HART over IP protocols. Depending on the application the isNet Lite is always used together with one or more fieldbus modules, where the isNet Lite is always the head module. Up to five different fieldbus modules can be connected to the isNet Lite.

You need a driver in the isNet Lite. It comes with HART over IP which will allow you to connect to HART instruments using any FDT or anything that has the HART IP server built in like SIMATIC PDM. In addition, you can add a license for either PROFINET or Modbus TCP by purchasing them.

isNet H@RT8 + AI module

The isNet H@RT8 + AI is a HART analog input module. It provides a 24V voltage source for connected HART field devices and it can measure the 4..20mA loop current for every HART slave. The module provides the process data to the isNet Lite Ethernet head module and to the higher level Ethernet fieldbusses like PROFINET or Modbus-TCP for further processing.

Different from the isNet H@rt8 Modules, every HART field device will be connected to the isNet H@rt8+AI by just 2 wires, which helps to keep the cabling simple.
