SIMATIC S7-1200, Digital input SM 1221, 16 DI, 24 V DC, Sink/Source
Special modules enhance the application area of the whole system, e.g. for Codition Monitoring, integrated weighing technology, simulation of input signal or for extending the power reserve for the S7-1200 real-time clock by an additional battery board.
Efficient fast error and error analysis localization with the new uniform display concept – plain text information of the error message in TIA Portal, on the HMI and in the Web server – shortens commissioning times and minimizes production downtimes. S7-1200 offers you diagnostic functionality already integrated in the system without additional programming work.
