Power industries (generation, utilities, grid, etc.) are also in the midst of digital transformation. The digital controllers and substation components like measuring equipment, protection equipment, etc. need to have a seamless transmission of data without any room for confusion that may lead to unwanted faults.

The International Electrotechnical Commission (IEC) in the year 2000 released a protocol that defines the standards of communication between the control system and the substation in an electrical power grid via a TCP/IP network. This ensures the interoperability between the control devices and the substation equipment for a smooth and error-free power system operation.

We at Utthunga have developed an IEC-104 device simulator, a protocol simulation tool that is capable of supporting 255 independent client nodes. The slave simulator can run on multiple platforms to test the compliance and performance of your IEC-104 masters

Why is the IEC-104 device simulator required for Industries?

IEC 104 communication protocol is a crucial aspect in the power grid networks where the process reliability is guaranteed by the speed and efficiency of how the devices share data and information between them. For efficient communication between electrical substation and control station, IEC 104 is one of the best and comprehensive communication protocol. However, to verify if your IEC-104 device complies with standard, in the luxury of your R&D lab, or your test lab, you must have an IEC 104 server simulator. These simulators help you pin point any errors and performance issues and also any standard compatibility issues.

In a sensitive environment like electrical utilities and substations where safety is of utmost importance, it is necessary to check your IEC 104 devices and communications through a simulator and correct them before any untoward circumstances arise.

IEC 104 Server (Slave) Simulator product provided by Utthunga

Product overview:
IEC 104 Server Simulator is a device (Slave) simulator tool, which can act as a virtual device on the IEC 104 network. Master (client) device and stack developers can use IEC 104 slave simulator tool to test the functionalities of their master and further troubleshooting. This tool ensures reliability as it was developed as per the specifications mentioned in IEC60870-5-101{ED2.1} standard document.
