In our rapidly developing world, new technologies, solutions and products are launched every day. Advanced communication protocols are needed for communication between the evolving technologies.

Industry bodies like BACnet International and FieldComm Group set specific communication protocol standards for different devices used in building and industrial automation.

Global players have to make their products compliant with such communication protocol standards. Some of the predominant communication protocols include BACnet, HART and ZigBee.

The Challenge

OEMs are facing the challenge of making disparate solutions and products work together. Standardization in the communication protocols helps to achieve the desired interoperability.

The SoftDEL Solution

We specialize in development, testing and integration of wireless and wired communication protocols such as HART, BACnet, Modbus, ZigBee and other proprietary and standard protocols.

BACnet (Building Automation and Control Network Protocol) is an ASHRAE, ANSI, and ISO 16484-5 standard protocol. BACnet is widely used in the HVAC industry for communication of devices used in heating, ventilating, and air conditioning control applications. It has also been widely used in lighting control, access control as well as in fire detection systems and their associated applications.


The HART (Highway Addressable Remote Transducer Protocol) protocol is the world’s leading, field-proven global standard, with over 40 million devices have adopted it. The penetration of HART-enabled products will continue to increase in future.

Users prefer HART Communication Protocol because it’s simple, secure and reliable, feature-rich and cost-effective.


Modbus, a serial protocol developed by Modicon in 1979, is an open communications protocol widely used in the industry for connecting industrial electronic devices. There are two data link communication versions for Modbus: Serial lines (Modbus RTU and Modbus ASCII) and Ethernet (Modbus TCP).


One of the most widely accepted industry standard for wireless personal area networking (WPAN), it is based on IEEE 802.15.4 RF standard.

ZigBee is ideal for devices such as handheld instruments, sensors and controllers, which may be located within a few meters of each other. ZigBee is rapidly becoming the choice for emerging smart, connected products.
