Modbus is a serial communications protocol published by Modicon (now Schneider Electric) in 1979 for use with its programmable logic controllers (PLCs). Simple and robust, it has since become a Standard communication protocol, and it is now amongst the most commonly available means of connecting industrial electronic devices. The main reasons for the use of Modbus in the industrial environment are:

*It has been developed with industrial applications in mind*It is openly published and royalty-free*It is easy to deploy and maintain*It moves raw bits or words without placing many restrictions on vendors

ModBus. What is it?

ModBus Protocols supported by MidNiteExtended MODBUS:

MODBUS-over-http: this is a home-rolled MODBUS transmission protocol where modbus PDU packets are sent over an HTTP channel. HTTPS is too heavy for our processor so we use a variant of the SRP key-exchange protocol in order to secure the communications. We use a secure block encryption utilizing large single-session keys. Each Classic is equipped with unique encryption keys so a compromised device can be blacklisted.
