Industrial Data Xchange (IDX) is a South African based IT industrial company with a global focus specialising in the provision of data communication solutions. On this blog, IDX experts comment on industrial communication protocols, trends, and tips as well as what is on the go in the labs at IDX.
Our company, Industrial Data Xchange, shares
its name with our software suite, IDX. IDX first came into being in 1995 as an
industrial data communications suite at a time when there were few options when
interconnecting real-time data systems between vendors. The original IDX
concept is fairly straightforward – it provides a pool of tags (or Slots) to
which various modules, akin to plugins, can commonly read and write real-time
data using Actions. The trick is that the modules implement the custom code to
interface with a specified system but also know how to share data into the IDX
tag pool. Therefore, as long as one has the modules developed for the system
one wants to share data between, IDX becomes a common real-time data hub. Over
time, many PLC, DCS and protocol-specific modules were developed, but for us,
the most frequently used are OPC DA, IDX TCP (our proprietary TCP protocol),
@aGlance, Gensym G2 and MODBUS, in the various flavours.
