Overview: Rockwell’s does not natively give a method to export controller tags from the PLC and import the tags as alarms to FactoryTalk. This can be problematic as some projects can contain thousands of alarms with mostly repetitive information. This article will serve as a guide on how to automate the creation of trigger
Overview In this post we will review how to setup a Modbus TCP connection between a Siemens PLC and an Allen Bradley PLC. While other means of communication exist (EtherNet/IP, Sierial, or using a gateway adapter) Modbus TCP has the advantage of requiring no special hardware and being a sudo-natively supported protocol by both platforms.
Overview: Although Siemens PLCs do not natively support EtherNet/IP communication, they possess the capability with a few extended programming instructions and a free-to-use library provided by Siemens. (see download links below) Unlike with a standard ProfiNet connection, the configuration will exist entirely within the PLC code, working around the limitation of the device and
