TECOMAT PLC controllers are consistently changing the way which professionals develop the structure of control systems for machinery, production lines and infrastructure facilities. Solutions implemented in each central unit of the TECOMAT family allow simultaneous communication with two system buses with very high speed transmission rate. CIB system bus with a capacity of addressing more than 4,000 binary inputs/outputs, or more than 1200 analog inputs/outputs /even in the smallest CPU of TECOMAT Foxtrot / transmits data at a speed of 153.6 kbit/s. TCL2 system bus transmits the information at a speed of 345kbit/s. Both buses allow to attach the peripherial modules anywhere up to 400 meters from the CPU without the need for additional repeaters or amplifiers. Even the smallest CPU allows the serve up to 10 loops of system buses /each up to 400 meters/ connecting the objects spatially placed on the installation.
