ET-CP-01 is the CPU module of ET-DCS system. It can be installed in any location on a rail ET-SM – place of assembly has no influence on proper operation. In whole ET-DCS system quantity of CPU modules is not limited. In case when several CPUs are installed on one bus one need to take into account that time synchronization can be set only on single one of them.
Basic tasks of ET-CP-01 are executing control algorithms, limitations and safety, exchange of data with process (directly by appropriate I/O modules or indirectly by communication links to other devices or controllers) and securing the data access for upper level systems (SCADA, DCS, MES, etc.).
Controller's application is designed by a programmer in one of programming languages defined in IEC61131-3 standard. The application, after being sent to the controller, is written in both internal flash memory and SD card accessible on rear panel of the device. It allows fast and easy exchange of ET-CP-01 module – after moving SD card to operational module it will automatic start the programmed actions.
CPU ET-CP-01 can work both as time server or a client with NTP or PTP standard.
