Introduction to Saving Energy in ControlLogix We all like to save money, and there are always a few tweaks you can do to your project for saving energy in ControlLogix. One of the simplest examples is lighting. When a light has been left on, shut it off after a certain Read More »
Introduction to the ControlLogix One Shot (ONS) The ControlLogix One Shot instruction triggers an event. Although this is a very simple concept, it’s difficult for many to grasp. It’s very difficult for some people to understand what cannot be seen! The one shot instruction allows outputs after it to go Read More »
Introduction to the Hour Meter on ControlLogix The advantage of having an hour meter on ControlLogix is for routine maintenance. With this purpose in mind, we use a retentive timer in conjunction with a counter. The counter will keep track of total machine run hours. Likewise, with an hour meter, Read More »
Introduction to ControlLogix Three-Way Switching Standard three-way switches are wired to control a light from two different locations. In this post, we will write a simple program to control lights from many locations. We will also set up the ControlLogix three-way switching to end up in the correct position. In Read More »
Introduction to Sump Level Logic When writing sump level logic, keep in mind, we need to know what the sump level is. We usually provide that to the processor with an analog input. We’ll assume that you have the level transmitter set up, we will scale this transmitter into inches. Read More »
Introduction to the ControlLogix SCL Command We use the ControlLogix SCL command to SCALE data. This simply means that we convert one range of values to another range of values. For example: We use a pressure transducer to measure pressure. A pressure transducer might convert 0 to 200 psi into Read More »
Introduction to ControlLogix Modbus In this document, we will walk through ControlLogix Modbus examples using the 1756-MVI56E module. The MVI56E-MCM modules allows connections between the Modbus network, and a ControlLogix processor. Before using the MVI module, we will need to set up the configuration such as the IP address for Read More »
Introduction to ControlLogix Trapping ControlLogix trapping is important for locating fast moving bits, or infrequent bits. An example would include equipment guard doors. Periodically, a guard door might loose connection, and shut down your equipment. Intermittent problems are very difficult to locate. Since the condition existed for only a fraction Read More »
Introduction to SLC to ControlLogix Messaging SLC to ControlLogix Messaging might be easier than you think. For example, the SLC 5/05 will take 5 integers from the N10 data file, and send those 10 integers to the Allen Bradley ControlLogix processor. The ControlLogix does not have the same addressing structure Read More »
Introduction to Creating a New Motion Project In this post, we will talk about creating a new motion project in Studio 5000. We will use an emulator processor to build virtual axis in the next series of posts. With Studio 5000, we will build this project based on the Allen Read More »
