IDX KNX Test Laboratory now offers device certification services
We are pleased to introduce IDX as a new certified ISO 17025 KNX Test Lab,
located in Johannesburg, South Africa.
IDX, a certified KNX Advanced Training
Centre since 2011, was thoroughly audited by the KNX Association and achieved
certified test laboratory status in May 2014.
We are therefore able to provide
interworking certification for your products according to volume 8/7/1 of the
Our hourly rate for testing is €75.00 per hour.
If you would be interested in considering
the use of our services, please contact us so that we can determine how we can assist you with KNX certification of your products.

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
