SIMATIC C7<br />
Control systems<br />
C7-636<br />
■ Overview<br />
6<br />
• Compact units for comprehensive applications<br />
• The CPU with medium to large program memory and quantity<br />
framework for the use, if required, of SIMATIC Engineering<br />
Tools<br />
• High processing performance in binary and floating-point<br />
arithmetic<br />
• Full graphics 5.7" STN di splay, color (256 colors)<br />
• 36 system keys, 24 user-configu rable function keys which can<br />
be labeled as required (18 with an LED)<br />
• With onboard I/O for use at machine level<br />
• With integrated PROFIBUS DP connection for distributed<br />
structures<br />
• Graphical and color visualizat ion and operator support for<br />
particularly user-friendly use<br />
A micro memory card and connector set are required for C7<br />
operation.<br />
