Troubleshooting/Service
If your machine is down, you need programming changes, or hands-on type help, contact us. In most cases, we can help.

PLC Programming
Bevan Engineering can supply PLC programming for almost any type of application. PLC programming services include PLC programming (Allen-Bradley Control/Compact/MicroLogix, Unitronics, Wago, etc.) and HMI programming.

Application Software Development
We are also able to provide custom application development in most mainstream languages. We generally use  Microsoft SQL Server  for all server based database development while using SQLite for local databases. The database design typically features a fully relational database (foreign key contraints, indexes, stored procedures, etc).


Speciality Applications
We can also provide product testing, data acquisition, and many other types of real-time systems to you using Labjack, Opto-22, I/O type devices. Many devices require the use of RS-232, USB, Modbus, and Ethernet protocols. Once again, we can help.
 
SCADA (Supervisory Control and Data Acquisition)
SCADA technologies are what sets Bevan Engineering apart from other engineering companies. SCADA is the interfacing of manufacturing processes with management systems. This is much different than just an HMI (Human Machine Interface) used for operator display.  SCADA allows data to be exchanged between equipment utilizing programmable logic controller (PLC) technology and one or more database servers. Recipe type data can be retrieved from a database and downloaded to the PLC. The results of a machine cycle can be uploaded and saved to that database.

Using SCADA technology, Poka-yoke rules can be enforced. The Japanese term "poka-yoke" means "mistake proofing". Poka-yoke is a manufacturing technique to prevent errors by designing the manufacturing process, equipment, and tools so that an operation cannot be performed incorrectly. We have years of experience designing and implementing this technology. Processes can be interlocked and prohibited from cycling unless previous operations have been successfully complete. Cycle times, idle times, etc can be saved. Your customer can view the results of every process required to fabricate the product they purchase from you.

While many companies rightfully choose to purchase a commercial product (Wonderware, Ignition, etc), Bevan Engineering offers several types of custom SCADA systems scaled to fit your facility. The best method for your facility depends on your current infrastructure, budget, and requirements.  The most common designs are:


1. Standalone. Recommended for non-serialized product.
2. Server based. Serves data to/from multiple processes. If product is serialized, poka-yoke can be implemented.
3. Fatory Talk Transaction Manager: Formerly called RSSQL (pronounced Rascal), this Rockwell software is designed to serve data to/from multiple process
4. WIP Controller: All PLC processors communicate with central PLC via messaging. Server application, connected to a database,  services the WIP controller. This design offers the fastest response time.
5. RFID: Control with optional serialization. All process values are stored on an RFID tag that each process read/writes.

All software written specifically for your organization is your property. Software engineers are almost always found "in-house", so you are able to maintain your system if you choose. With Bevan Engineering, you are always in control of your investments.

lnline SPC
Using Windows Embedded touchscreens, customized SPC software can be written to monitor your process in realtime. In some cases, spec limits are not known when hundreds or even thousands of of product types are not known. so an inline SPC package helps determine them. Your competition is striving for zero defects - so should you.

Controls Design/Build
Bevan Engineering can provide mechanical and electrical design and fabrication through one of our OEM partners. If you prefer a turnkey system, we can help.
