Bangladesh is a developing country. With the continuous development process numbers of industries are increasing as well. Almost all the industries run on PLC automation systems. PLC Automation Includes combining all the controlling devices into a single or Multiple PLC [1]. There can be various controlling devices such as magnetic contactors, relays, sensors, and other loads which include a coil. These controlling devices can be operated by PLC through PLC Programming. There are two kinds of control. One is Digital another is Analog. To operate a Digital load, you need to use a digital module and for controlling an analog load or operation you need to use an analog module. Almost every PLC brand has both its Digital as well as Analog modules. The various company uses a various brand of PLC’s. Among all the brands, Delta DVP Series PLC are very popular. There are various Delta PLC Types as well as Delta PLC Modules. We will discuss how Delta PLC has established itself in Bangladesh’s automation market. Dhaka’s best Delta PLC Training Center, Multipurpose Engineering & Industrial Automation offers comprehensive Delta Automation training.

Delta DVP Series PLC — Introduction to Delta Automation 

The Origin of Delta Company is basically Taiwan. But most of us know it as a Chinese Brand. Which is totally false. Most of the automation companies of Bangladesh sell the copy Products of Delta Electronics. So, they try to frame it as a Chinese Brand. Delta PLC’s price is comparatively cheap than other PLC Brands. Although, some analog input modules of Delta PLC can be quite expensive. Also, it’s smaller in size with a compact design. All these reasons make the Delta DVP series PLC a wise choice for the automation engineers of Bangladesh. There are various PLC Models in the fleet of Delta DVP Series. Some popular Delta DVP models are Delta SS2 PLC, Delta DVP SX2, Delta DVP SX, Delta DVP SS etc. Along with PLC, Delta also provides VFD, HMI, and other automation products. Which are also gaining popularity in Bangladesh. The Delta Automation Training Center in Bangladesh will teach you everything you need to know.

How To Operate  Delta DVP Series PLC

Delta PLC operates similarly to other well-known PLC brands like Siemens, Mitsubishi, LS, Fatek, etc. We need PLC hardware, communication software, and communication cable. The software we will be using to operate our Delta PLC is known as WPLSoft [2]. There is another Software for operating Delta PLC which is Known as ISPSoft. Although ISPsoft is not as popular as WPLSoft [3]. The best part about WPLSoft is it’s free. Anyone can download and install WPLSoft from the official website of Delta Electronics. Moreover, the software is easy to install. Multipurpose Engineering and Industrial Automation will walk you through the Delta PLC Software installation.
