PLC Programming

Our automation engineers have over 20 years of experience developing industrial automation solutions, software being our focus with PLC’s being our engineering way. From documentation up to the PLC code we develop full solutions for new applications or upgrade- migrate the existing one.


WA creates brand-new PLC solutions from conception to completion, including the creation of functional specifications, online and offline programming plus on-site commissioning. To save startup time, we provide real process simulation before FAT and remote commissioning services. WA can advise on the choice of automation components, AS/OS architecture, trains our clients and follows programming standards with reusable code and function-based architecture that respects IEC 61131-3 standard.

Hardware/Software platform expertise: Siemens, Beckhoff, Omron, Mitsubishi, Schneider Electric, Yaskawa, Delta and others.

HMI Programming

PLCs, or Programmable Logic Controllers, manage production equipment in the context of industrial automation. It is worth noting that automation was previously used in large manufacturing enterprises, but its application has grown significantly in the past years. People are important in the operation, troubleshooting, and maintenance of these complex automation systems and adding an HMI will interface the operator with the process or equipment.

The Human Machine Interface (HMI) is a device that allows you to enter process parameters or commands into your machines to operate as directed and receive feedback on their status. In other words, an HMI is an industrial computer that has been properly configured to communicate with the PLC and the plant operator or system administrator.

HMI programming differs significantly from most other programming languages. HMI is a visualization of a process in a production area primary representing the P&ID or PFD of the plant. The development of the screen layout is given special consideration when developing HMI. Furthermore, the programming that will control the HMI's will typically be a part in the PLC.

To observe the graphics and control operations taking place inside a PLC or other controller, a graphical interface is essential for industrial automation. HMI and SCADA are the two most often used graphical interfaces.

SCADA is for Supervisory Control and Data Acquisition, and HMI refers for Human Machine Interface. Both perform the same duty of graphical presentation, although they differ slightly from one another.

An HMI is a standalone device that only has to be powered on running its own Operating System, whereas SCADA is software that must be installed in a PC in order to function. The HMI It requires a separate power supply whenever it is mounted because it is an independent device, as opposed to a PC, which can typically be powered up as we use it during the day.

When a plant has several different processes running a number of HMIs will thus be needed for the various processes, in that instance. Naturally, a single HMI can manage every process.

HMI has some limits, particularly in terms of communication. The communication between several PLCs won't be significantly slowed down, and the data won't be displayed in a timely manner, but as additional controllers are added to a single HMI, there will be some communication lag and the data will be displayed more slowly.

SCADA is specifically made for situations like these when you need to display every plant process on a single screen. It allows for more faster communication and smoothly displays all of the data. Cheaper than SCADA is HMI. If you just need to control two processes, connecting a single HMI to two PLCs makes more sense than using a SCADA

In many instances, HMI and SCADA are even utilized in tandem. It becomes sense to connect multiple HMI’s for separate stations in our described example of multiple processes so that the local operator can readily grasp them. Additionally, attach a SCADA in the main control area so that an engineer can monitor the entire facility.

Apart from the server-client function, HMI generally has all of these features as well. However, even with the functions that are offered, it still has significant restrictions as compared to SCADA. It's because SCADA, which is made to handle large-scale processes, must always be at a higher level to effectively control the plant.
