Create Controller Fault Routine

Check for a Specific Fault In this article,  we will learn how to clear fault on Allen Bradley PLCs.  Which is the continuation of our previous article. We will examine the automatic cleaning of the fault types that we have determined specifically, and error notifications at prescan time. You can find our previous article at the link below. Let's continue with an example on Control Logix PLC with Studio 5000. 1. The first EQU instruction checks for a specific type of fault, such as program, Input/ In Source B, enter the value for the type of fault that you want to clear. 2. The second EQU instruction checks for a specific fault code. In Source B, enter the value for the code that you want to clear. 3. The first CLR instruction sets to zero the value of the fault type...

Communication Modules Communication modules provide data exchange between PLCs and input- units or between other personal computers. These modules can be operated by direct connection (point to point) or over a network. In a one-to-one connection, the connected processor includes a dual interface. While one computer port is accessed by the programming device, communication is provided through the other. Thus, it is possible to include more I / Q in the system. In addition, data...
