ModBus. What is it?
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 MidNite
Extended 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.
