This site offers several test tools useful for the SCADA industry. The primary one, CDOAN-DNP3, is an advanced test tool for DNP3 protocol, having recently (June 2024) been enhanced to support an external scripting language. CDOAN-DNP3 was, at one time, offered at no charge. There are now several hundred units in use, and will soon (August 1, 2024) no longer be free. But, the charge will still be small, US $89, only enough to help maintain the web site.
