KATREN controller is designed to convert analogue and discrete signals into digital form, to exchange information with the upper level, to execute automatic control programs, as well as to control subordinate devices of the automation system. The controller is designed for use in the construction of multi-level distributed systems as the main and subordinate controllers of the lower level. The serial interface RS-485 is used to control the subordinate controllers, the interaction takes place via MODBUS protocol, the controller exchanges information with the devices of the upper level via Ethernet.The controller has the possibility of flexible layout - the required number of channels of each type in the controller is formed by input/output modules, the composition and configuration of the controller are determined in the design process and when ordering the controller at the manufacturer's enterprise.
