    USER MANUAL – Z-KEY 1. Glossary  Modbus RTU An open protocol for the serial communications developed by Modicon Inc. (AEG Schneider Automation International S.A.S.). Simple and robust, it has since become a de facto standard communication protocol. For more info http://www.modbus.org/specs.php...
  • Page 8 USER MANUAL – Z-KEY The Client (called Master in Modbus RTU) establishes a connection with the Server (called Slave in Modbus RTU). The Server waits for an incoming connection from the Client. Once a connection is established, the Server then responds to the registers queries from the Client.
