The ecoSYS control system utilizes several network connections for communications. The key differences in these networks are determined by the in-store vs. out-of-store connections.
Communication to and out of the store is made easy with ecoSYS' ethernet capabilities. From a standard ethernet port, customers can choose to connect the Site Supervisor to a private WAN, a network connection via an Internet Service Provider, or a cellular modem connection. In each of these instances, a secure connection can be made that is password protected so that only approved persons have access to the system and data.
Most of the general purpose input and output communications devices required by the Site Supervisor to control refrigeration, HVAC, and lighting systems are connected to the controller via the I/O Network. The I/O Network is an RS485 three-wire connection that allows data interchange between input boards (which read sensor values and digital closures), output boards (which carryout commands from the controller), and the controller.
Additionally, the Site Supervisor controller can also communicate via its MODBUS network to various devices including the Light Commercial Communicating Thermostat. The thermostat enables the controller to read status information from the device as well as send operational setpoints.
