PPD113B01-10-150000 3BHE023784R0123 Extended PLC Control System
PPD113B01-10-150000 3BHE023784R0123 has outstanding advantages such as high reliability and strong anti-interference ability, and thus it is widely used in the field of industrial control and has become one of the main pillars of modern industrial automation. In the design of PLC control systems, often encountered I / O point resource constraints as well as cost-effective contradictory issues.
PPD113B01-10-150000 3BHE023784R0123 controlled devices need to have a manual, automatic mode of operation, and the manual part of the control buttons are more; some automatic production lines, position detection of the travel switch or for the system working status indication of the output of the more, will make the occupation of the I / O points greatly increased.
PPD113B01-10-150000 3BHE023784R0123 generally solved by increasing the expansion module, but the PLC’s I/O points are expensive, and there are a number of expansion modules and I / O points to limit the number of purposes, such as SIEMENS CPU 226 maximum number of expansion modules for the 7, the maximum extension of the 168-way digital I / O points or 35-way analog I/O points. If this time and then increase the CPU, is bound to make the system cost-effective greatly reduced, in this case, the expansion of I / O points has greater practical significance.
