In industrial applications, data is worth something. And, accelerating and analyzing the vast amounts of raw data that is shaping the Industrial Internet of Things (IIoT) as we know it today is what drives acceleration across the industry. One area where the impact of the IIoT is being felt is the collection of I/O data from field devices. IIoT increasingly requires networks to push collected I/O data to OT (private cloud) and IT (public cloud) platforms for analysis. Typically, Modular Remote I/O is used to retrieve I/O data. Unfortunately, they create pain points that not only frustrate engineers but also impact day-to-day operations. In this article, we take a closer look at these pain points and discuss a solution that will appeal to both OT and IT staff. Módulo ZIGBEE
The reality of reconfiguration
One of the biggest difficulties with a modular remote I/O setup is copying configuration settings to the current module with a different combination of modules. After adding, moving or deleting one of the modules, the configuration of the unchanged module (including Modbus address and RESTful API to the upper software) needs to be reconfigured. Ideally, system integrators would like to preserve all completed settings between devices and upper-level software, and only configure newly added modules with minimal effort.
However, the reality for system integrators involves lengthy and repeated reconfigurations when dealing with combinations of different modules in different sites. For example, suppose the module combinations in Site A, Site B, and Site C are AABBC, AAABBC, and AACBB, respectively. Replicating the configuration settings of the I/O modules in site A to the configuration settings in sites B and C is not that simple. In site B, an additional module (in the diagram, represented by A) is added. Therefore, SI not only needs to configure the newly added module, but also needs to reconfigure modules B, B, and C. The same frustrating situation applies to site C, where a module has been removed and replaced by another module (in this example for C) ). Here, module C needs to be configured from scratch, and the two modules identified as B need to be reconfigured. Much to the chagrin of system integrators, just adding, removing or moving individual modules requires extra effort. Therefore, eliminating reconfiguration in repetitive configuration setups will save a lot of time and money. kits de prueba
The correct protocol is crucial
Modular remote I/O is also annoying when it comes to protocol support. Much of the modular remote I/O on the market does not support IT protocols familiar to many engineers, such as SNMP and RESTful. Therefore, engineers have to spend more time and effort to complete their projects, because the modular remote I/O only supports OT protocol. Finding a solution that supports multiple OT and IT protocols in one device makes a world of difference.
