SIMATIC DP, PROFINET IO cover caps for push pull sockets (1L +, 2L+) Power, 5 pieces per packaging unit SIMATIC ET 200pro is a very robust and powerful modular decentralized I/O system for installation outside the control cabinet directly on the machine with protection class IP65/67. The modules can either be plugged directly into an ET 200pro CPU or connected to a central controller via PROFINET or PROFIBUS. The connection to the central controller is also possible wirelessly via WLAN, which enables the SIMATIC ET 200pro to be used in electric monorail systems, driverless transport systems, in building management and in warehouse logistics. Thanks to its extensive range of modules, it is used in particular where a finely modular structure with different functions is required under harsh environmental conditions. The separation of the module and the bus/power connection technology enables a module to be replaced during operation (so-called hot swapping), which, in conjunction with the detailed diagnosis, ensures the availability and productivity of the machine.
