I have often been asked if there is a possibility to convert from Modbus to Ethernet and then back to Ethernet, in other words the information needs to be bridged across an Ethernet infrastructure. Anybus is now meeting these requirements using wireless technology with a clever and robust solution.
How it works
The wireless modules act as a wireless bridge where a physical cable would usually be installed. What makes this wireless module so impressive is its ease of use. The simplest configuration is a point to point connection.
The wireless modules require relative little configuration which is all done via the buttons on the modules. The modules will scan for the device that it is connected to and learn the MAC address (physical address) and IP address of the device. Both modules will need to learn the device that they are connected to, from there it is just plug and play. Since the module take on the IP of the device that it is connected to, the modules appear completely transparent hence no changes to your system.
This isn’t the only topology configuration that you can select but it is the easiest. The modules have a built in web server to configure more advanced stings and this allows you to connect to existing wireless networks.
The wireless modules support 802.11 b/g and 2.4 GHz and 5GHz versions. The modules have a built in antenna with a half radio globe coverage, this is used to concentrate the signal giving the devices better range. The modules are also IP 65 rated and are perfect for industrial applications and are hopefully Africa proof.
The only negative aspect to the product is that the Ethernet connection and the power are connected using M12 connectors making setup take a little longer but this will definitely make them more weather resistant in the long run. The wireless range is up to 400m.

Last week IDX were called to site at a large commercial residence building in Pretoria, South Africa. Where our client was implementing an IoT solution for remote monitoring and control of various HVAC and power systems in the building. The control system the SI chose in this case was a Modbus enabled Industrial Micro PC called the Revolution PI. The client had Modbus sensors connected to boilers, air conditioning systems, ventilation systems and power meters. The Modbus communications between the controller and the sensors were intermittently failing due to various installation and implementation faults: 1. Earthing and Shielding Within any fieldbus communication installation, one of the requirements to ensure uninterrupted operation is to implement adequate grounding and shielding techniques. Effective grounding and Shielding help to prevent electrostatic and electromagnetic pickup, which can lead to failed communications. Some of the shielding and grounding req
In this blog, I will discuss the steps involved in getting the Netbiter to record and display values coming out of the ComAp Generator Panel, so that one can do remote monitoring and control of the generator. The Netbiter Model used in this case is the EC220 and the panel used is the InteliLite AMF 26 P. The steps followed here can be applied to any MODBUS device due to the generic nature of the Netbiter. S tep 1 - Physical Connection Check that the Control Panel has a communication module attached to the back of it. You will need to establish the medium (RS458/RS232) and the protocol spoken (MODBUS RTU/ASCII) - all of this information will come from the user manual of the generator. Finally confirm the communication settings (baud rate, parity, stop bits, etc) - these can sometimes be changed so check what they are on the actual panel. In this case, we have the following settings: MOUBUS RTU over RS232 (you'll need an external converter to convert the RS232 to RS
Hopefully this post will help you if you are having trouble finding the IP address of your Anybus X gateway. The MODBUS TCP Client Range of these gateways enable you to control a MODBUS TCP server and port that information to a whole host of different protocols such as PROFINET, PROFIBUS, DeviceNet, etc. When you get one of these units out of the box, you shouldn't have any problems searching for and configuring the gateway on your Ethernet network, but sometimes you are given a configuration that has been used in the plant already and now you need to make some changes. So what is your first step? Install and run the Anybus IPconfig tool (available on the Anybus website or on the the CD that comes with your unit). Assuming your physical Ethernet connection is intact, you should be able to scan the network for any HMS devices that are connected to the network. Tip: I would connect and Ethernet cable directly to the Gateway from the PC and disable the wireless card to
