Programmable Logic Controllers (PLCs) are a great way to control, measure, and carry out tasks in complex manufacturing and industrial applications. These controllers can communicate with many other systems you have in your operation. PLCs can easily interface with a PC, PACs, motion control devices, HMIs, and other common types of systems.
The simplicity, power, and interoperability of these devices often make PLCs a popular choice among automated weighing solutions.
It has been our experience over the years that most clients in all industries experience some degree of problems (or pain) with some system or process within their facility. That pain can be:
Financial in that they are spending too much time and money on a legacy system that needs updated or replaced.
Productivity in that the system they are using may no longer be performing as efficiently as it once did due to changes or enhancements in operations.
Support-related in that they are not receiving cost-efficient, timely, or satisfactory support.
With our 100+ years of combined scale experience and the combination of industry knowledge and technical expertise, BTEK Automated Weighing Solutions can help solve your most challenging applications with robust hardware/software solutions that implement the latest in technology.
Why PLC/PAC integration with Brechbuhler
A weighing system that can't talk to your PLC or PAC is a weighing system that becomes an island on your production floor. Brechbuhler engineers weighing hardware and control logic together, so your scales become an active part of your automation architecture instead of a standalone device someone has to check manually.
Choosing between a PLC and a PAC
PLCs excel at fast, deterministic control of discrete processes, while PACs bring more advanced data handling, networking, and programming flexibility for complex, multi-process operations. We help you decide which platform fits your weighing application, or work within a controller you've already standardized on.
Interfacing with your existing systems
Our weighing controls are designed to interface cleanly with PCs, other PACs, motion control devices, and HMIs already in use at your facility, so a new weighing system doesn't mean ripping out and replacing infrastructure that already works.
Migrating legacy control systems
Many of our clients come to us running legacy control packages that are difficult to support or no longer serviceable. We help migrate these systems to standardized, field-serviceable PLC/PAC platforms without unnecessary downtime.
Core PLC/PAC solutions
Custom weighing logic and programming
We program controller logic specific to your weighing application, whether that's batching sequences, check weighing thresholds, or multi-scale coordination, rather than relying on generic off-the-shelf templates.
HMI, SCADA, and ERP connectivity
Beyond the controller itself, we help connect your weighing data to HMI displays, SCADA systems, and ERP platforms, so accurate weight data flows into the reporting and business systems your team already relies on.
PLC/PAC controller FAQs
What's the difference between a PLC and a PAC for weighing applications?
A PLC is generally built for fast, reliable control of discrete tasks, while a PAC combines that control capability with more advanced data processing and networking. For most straightforward weighing applications a PLC is sufficient, while complex, multi-process operations often benefit from a PAC.
Can you integrate a new weighing system with our existing PLC?
In most cases, yes. We evaluate your existing PLC platform and communication protocols to determine the best way to integrate new weighing hardware without unnecessary replacement of working infrastructure.
Do you support migration from legacy or unsupported control systems?
Yes, we regularly help clients migrate from legacy or hard-to-support control packages to modern, field-serviceable PLC/PAC systems, minimizing downtime during the transition.
Can your systems connect to our ERP or SCADA platform?
Yes, we design our weighing and control systems to communicate with common ERP and SCADA platforms, so weight data becomes part of your broader plant data rather than living in isolation.
Do you provide ongoing support after the PLC/PAC system is installed?
Yes, our service and support extends beyond installation, backed by our combined 100+ years of scale and controls experience to help keep your system running as your operation evolves.
Do you service PLC/PAC controlled weighing systems outside of Ohio?
Yes, our technicians travel to service PLC/PAC controlled weighing systems across a wide service area beyond Ohio. Contact us with your location and we'll let you know how we can help.
