SITES provides a system to maintain, administer and control industrial plants. Keeping in mind the nstallation's maintenance cost. To obtain a system with optimum and versatile control, several Master modules that control a series of Slave modules are provided; the Slaves acquire data at the field level. In each installation there is only one Master and a certain number of Slaves (according to the installation's size). All these modules are connected through RS-485 network, ideal for industrial facilities. To increase reliability, two separate communication lines are used, if the Master doesn't receive any response from a line, it will try the other one.
