One of the most popular and efficient ways to send contact closures over Ethernet is using RTUs. Using RTUs to Send Contact Closures Over Ethernet Learn how an efficient remote monitoring device is able to collect your contact closures and send it all to you - wherever you are. That's why, in this article, we'll dive into how the right technology allows the transmission of digital contact closures to a remote point using Ethernet. This is because connecting your devices via Ethernet over LAN brings you many benefits, such as:ĭespite being a popular data transmission method, many network technicians still have many questions on how they can properly send contact closures over Ethernet. So, your system needs to be able to transport alarm data to your master station in an effective method.Įthernet is now one of the most common data transmission methods in network monitoring. For example, in remote sites you'll have discrete alarms for things like:Īlthough contact closures are a very common type of alarm in remote monitoring systems, they will only be efficient if they can reach you in a timely manner before a condition escalates into a network outage. These types of alarms are very common in many different remote sites where networks are located. Contact closures are the alarm points that can be only "ON or OFF", "opened or closed", or "Yes or No".Ĭontact closures may be an "old thing", but you can't ignore them. Contact closure is the term used to describe discrete alarms, digital inputs, or simply alarm inputs.
