Plus, there is no commission from links below. Introduction: Zebra printer seems to be quite popular in the industry. The Japanese grocery store Maruichi, the Vietnamese restaurant Pho Minh Ky, my ex (employer, not girlfriend), etc. However, it can be painful if you need to integrate a printer with an Allen-Bradley CompactLogix controller. If your printer only has light indicators but not an integrated display like ZD420/421, you'll have to look up the troubleshooting guide to figure out the meaning. (And yes, we don't like looking it up online if there is already an HMI around.) If you dig around on the Internet, you'll probably see an article on PLC.net that talks about opening sockets for communication. However, that can be tricky and time-consuming if you don't have sufficient IT kn

You can read this post on LinkedIn as well. Introduction The support on string datatype in EBPro Macro falls short. I complained about it in my last article GetData()/SetData() and Error C45 in EasyBuilder Pro (EBPro) . When I contacted Maple Systems' technical support, they couldn't answer my question and played dead in hope that I would walk away. And I did, disappointedly... Luckily, the solution dawned on me last night. Now let's learn! Section 1: Limitations of String Datatype in EBPro Macro If you create an ASCII input object in EBPro, you can choose from Unicode or UTF-8 encoding. For Unicode, each word reads 2 bytes . In contrast, each word reads 1 byte for UTF-8. Section 2: The Problem with Extra Spacing in ASCII Objects If you limit your usage to very basic functions on HMI, you have nothing to worry about. However, if you write a Macro to play with these ASCII objects or read/write them to/from your PLC controller. You may run into a problem like this.

You can read this post on LinkedIn as well. Introduction: I started my PLC and HMI programming journey with Allen-Bradley products in 2020. Due to a career change, I landed in the Greater Boston Area in 2021 and launched an excursion to learn the Maple Systems HMI (and how powerful a Macro function can be). However, learning Macro isn't all that bright and shiny. I ran into a problem when using PLC tags (still an Allen-Bradley CompactLogix controller). When I compiled the Macro, it gave me a C45 error message saying "The tag can't be found." What? I SUCCESSFULLY imported every single tag already! That burning feeling brings me back to the objected-oriented programming class in 2013. I struggled and couldn't make any progress. Later, my colleague told me why that happened when he checked in with me. So here we go to learn what was the root cause! Section 1: Understanding the Controller and Program Tags For a 5000 series controller from Allen-Bradley, you use Logi

You can read this post on LinkedIn as well. Introduction: The Allen-Bradley module 5069-SERIAL, released in 2018, offers enhanced communication capabilities for various protocols, including DH-485 and DF1, through a firmware update V2.012 in 2020. While the user manual lacks practical examples for sensor communication, this comprehensive application note aims to fill that gap. Specifically, we will focus on integrating the module with the Panasonic HL-G112 Laser Displacement Sensor. By following the outlined setup process, you can avoid pitfalls and accelerate your prototype development. Fig. 1 Section 1: Understanding Sensor Specifications: In this Application Note, I pick Panasonic HL-G112 Laser Displacement Sensor for development. I'll walk you through the entire setup process so that you can stay away from traps and have your prototype hit the ground running earlier! Fig. 2 Let's start with the sensor specification sheet.

You can read this post on LinkedIn as well. Introduction: ProSave is a powerful software tool developed by SIEMENS. It's designed to streamline data management tasks for Siemens S7-1200 and S7-1500 series PLCs. It also communicates with SIMATIC HMI devices. ProSave provides backup, restore, and data transfer operations so that we can use ProSave for project management and ensure system reliability. Join me as we uncover the power of backups, explore the realm of password-protected projects, and uncover a surprising discovery that may leave you running to check your devices. Section 1: Backups for Peace of Mind In the vast landscape of ProSave, we encounter a crucial feature that stands tall—the ability to generate backups of PLC/HMI projects. These backups serve as a safety net, offering swift restoration in the face of PLC/HMI failures or during project migrations. Whether you seek to safeguard the entire project or specific components such as hardware configurations, user progr
