Alarms in C++ programming Introduction Essential alarm status features Every alarm is oriented towards the OPC UA Alarms & Conditions specification and has these properties: Property Meaning or purpose Restrictions AlarmId The unique name of the alarm on the device. AlarmType… Read More
Introduction to Applicative System Redundancy (ASR) Available with AXC F 2152 and AXC F 3152 The Applicative System Redundancy (ASR) is carried out by providing two redundant PLCs (First and Second) in the same network together with the responding I/O stations. The communication between the PLCs and the I/O stations is based on the PROFINET… Read More
Proficloud Device Management Service Available from 2020.6 with AXC F 2152, from 2021.0 LTS with most PLCnext Control devices (details see below) In this topic, you read how to add, edit, or remove your devices to the Proficloud. Scope of the Proficloud Proficloud offers an easy way of managing and maintaining remote PLCnext devices, such as controllers in off-shore wind power… Read More
Notification Manager Use Case Notifications in PLCnext Technology are messages referring to special events. The Notification Manager enables sending and receiving notifications between components of a controller. Notifications can also transport user data (payload) which is information data without control or protocol information (no process data, no real-time… Read More
Running applications in OCI containers Available from 2020.0 LTS PLCnext Control devices are ready for running applications out of OCI containers. For many years, the use of OCI-compliant containers (such as docker®, moby or balena) have revolutionized the IT landscape. They allow a much faster and easier reuse of existing or custom… Read More
System redundancy with RFC 4072R Available from 2022.0 LTS with RFC 4072R The RFC 4072R is a high-availability PLCnext Control with redundancy functionality. Some commissioning steps differ from those for other PLCnext Control devices. In the course of the system redundancy with RFC 4072R, we describe only these differences. Creating a new RFC 4072R project In PLCnext Engineer software,… Read More
