Procedure for Connecting Allen Bradley PLC and PC – RS Logix 500

In this article, we will learn the step-by-step procedure of connecting the Allen Bradley PLC and a PC (computer) in RS Logix 500 software.

In this article, we will learn the procedure for reading or searching the tag number in Siemens PLC using Simatic Manager software.

Here we discuss intrinsic safety barriers and their importance to maintaining safety at the highest level in DCS or PLC control systems.

In this post, we will see how to configure PID controller in various Schneider PLCs (programmable logic controller)

In this post, we will see the concept of high-speed counters and fast counters in PLC (programmable logic controllers).

Identify PLC critical alerts and program a trap to monitor the trigger conditions and the alert state for any deviation.

Measure and provide a baseline for memory usage for every PLC controller deployed in the production environment and trend it on the HMI.

Store PLC hard stop events from faults or shutdowns for retrieval by HMI alarm systems to consult before PLC restarts.

Log PLC uptime to know when it’s been restarted. Trend and log uptime on the HMI for diagnostics.

Summarize PLC cycle time every 2 to 3 seconds and report to HMI for visualization on a graph using trend.
