Aside from the standard functionality the Patron S167, M267 and M567 controllers also feature an LTE interface and a SIM card slot, allowing them to utilize LTE wireless network for internet access. What are the advantages of this functionality?
Primary network connection
Modern SCADA technologies give operators or owners of various automation projects the option to monitor and manage the controlled technology remotely via the internet. Operational data can be relayed to a supervision centre which can then perform remote management of technologies placed even in distant locations.
For remote access and control, it is necessary to connect the controlling system to the internet. However, if the technology is placed in a remote or inaccessible location, or if the already existing connectivity cannot be used for some reason, the connection cannot be set up. In this case, the owner or operator is facing financial expenses related to the installation of a suitable infrastructure.
Given their advantages and wide functionality, the Patron LTE controllers are an excellent choice for such cases. A distinct advantage of Patron LTE PLCs is a very easy installation that does not require any detailed networking knowledge. All that is needed in the given location is then only a stable mobile network coverage.
Backup network connection
In the field of industrial automation, the ability to react in time to any downtimes, failures or other issues is critical. Continuous monitoring of operating data allows spotting any trouble well in advance and take necessary precautions before a critical failure occurs, preventing considerable financial loss caused by production downtimes, component damage etc. Programmable logic controllers utilized in such systems usually communicate with individual devices, read their operating data and forward them to various SCADA interfaces in supervision centres.
If the primary connection fails, the communication between the technology and the supervision centre is interrupted. Such failure is not always immediately noticed and a delay between detecting the failure and its solution can occur, during which the supervision centre is not receiving any notifications or alarms. This situation creates a risk of delayed response to any potential issues.
The LTE interface of Unipi Patron S167, M267 and M567 controllers responds to a primary connection failure by automatically switching to LTE communication, ensuring the link between it and the supervision centre is maintained. By preventing communication loss, the supervision centre retains an overview of the technology even during the time needed for locating and fixing the cause of the failure.
