#278 - Rockwell How to create a PlantPAx project from Application Code Manager (ACM)

- Download the latest version compatible version of the Process Library.

- Launch the ACM setup installer in order to install the process library project template in the ACM. Note: Get ACM v5.00.00 or above for controller v37.

#276 - Rockwell PLC Simulator (FactoryTalk Logix Echo)

- There are different methods of connecting to the PLC Simulator, either by creating the Controller or by importing the Controller from a project (ACD file).

#275 - Rockwell PlantPAx Introduction

- Download the Library of Process Objects from the "Compatibility & Downloads Center". Example: Process Library v5.20.02.

- Configuration (e.g., Analog Input block) is done through the dialog box of the object block in the FBD. It uses the Scientific Apparatus Makers Association (SAMA) diagram format, within Studio5000 (version above v33).

- Controllers: ControlLogix 5580 Controller 1756-L81EP, 1756-L83EP, and 1756-L85EP. These hardware have embedded the PlantPAx functions. Controller faults such as wire break, IO fault or short-circuits are not needed to be configured as input to function blocks, because they are embedded.

#264 - FTOptix How to activate/deactivate a license

- In the Server open the "Entitlement Manager":

#260 - Troubleshooting a Stratix Switch

- The easiest way to configure a Stratix switch is through the Express setup. To activate it press and hold the button for about 20 seconds, then press for another second until the configuration port starts to blink.

#244 - Studying a PLC programme with the RSLogix Emulate500 emulator

In this post we will study the Simple Motor Control Building Block programme, downloaded from the Rockwell website and opened in RSLogix Micro Starter Lite and simulated with RSLogix Emulate500.

#118 - Chat with Diego Moreira [Part 2]

(English version at the bottom)

Na última terça-feira 12 de Outubro, tive o prazer de bater um papo com meu amigo Diego Moreira, especialista técnico em acionamentos elétricos que possui uma sólida bagagem em inversores de frequência. Diego trabalha com clientes de diversas indústrias, auxiliando setores como mineração, açúcar e álcool. O foco da nossa conversa foi sobre dicas práticas para comissionamento e monitoramento de inversores de frequência e sistemas de acionamento. 

#109 - Rockwell Automation Fair from Home

This year it is possible to attend virtually the Rockwell's Automation Fair from November 16 to 20, by registering in this link. 

That's a great opportunity to learn and to see the state of the art in automation. 

#77 - Rockwell PLC firmware flashing

Flashing the PLC’s firmware is part of the routine of an automation engineer. Manufacturers are constantly updating their firmware, as part of continuous improvement but also to correct bugs and cyber security flaws.

#72 - Rockwell PLC change version of project

In this post a project version upgrade in a Rockwell PLC is described. This could be useful to keep the project in sync with the latest corrections done by the manufacturer, such as improvements related to cyber-security.

#71 - Checking TCP/UDP ports and applications

In industrial networking it is important to know the TCP/UDP protocols that the devices are using to communicate. In this post two interesting websites are shown that can be useful during configuration of the rules in a firewall and to increase the cyber security of the factory.

#69 - Rockwell PLC searching inside program

On this post two options that exist on the Search tab menu are shown. They are called "Go to..." (shortcut Ctrl+G) and "Browse Logic..." (Ctlr+L).

#61 - Backup Managed Switch

The Rockwell Stratix Layer 2 managed switches have a dedicated slot to install a  special Secure Digital (SD) card. The role of this SD card is to simplify the device replacement and also the device configuration, particularly in cases where several switches have the same configuration. 

#54 - Rockwell PLC FIFO instruction with Load and Unload

FIFO (First-In First-Out) is a concept widely used in logistics and it means that the first item that enters the stock, must be the first item to leave the stock.

#49 - Rockwell PLC array to stack data

In this post we will create a simple routine that will stack data in an Array. The main instructions used were LEQ  for comparison , a CTU counter that increases the storage index and is reset with RES, and MOV to move the data according to the index. 

#48 - Rockwell PLC BTD Bit Field Distribute and Bit Mask on Word

The Bit Field Distribute (BTD) instruction can be used to copy bits from one variable and write those bits to another variable. A practical application is in identifying the status of a process, when only some of the 16 bits of an INT variable are used. In the example below, the last 4 bits of value_1 are copied and written to the first 4 bits of value_2.
