When you close the SW gate, the effect is either canceling or interrupting, depending on the
parameter assignment. The digital input DI remains active even when the SW gate is closed.
Further possible causes of parameter assignment errors with the latch function:
• Incorrect parameter assignment of the digital output function (Function DI)
Expanded Feedback Interface
If the 1Count5V/500kHz is inserted behind an IM 151 that supports the reading and writing of
broader user data interfaces, the current count value can be read from bytes 8 to 11 of the
feedback interface.
