How do you implement the LOGO! Pulse Relay function in STEP 7 Micro/WIN?
This entry provides you with a STEP 7 Micro/WIN library that includes a block for a pulse relay function.
The pulse relay (block: Pulse_Relay)
Fig. 1: Pulse_Relay block
|EN||[BOOL]||ENABLE: enabling of the function, must always be TRUE (1)|
|Input||[BOOL]||Signal input, with a rising edge (0->1) the output is set or reset|
|Set||[BOOL]||Setting the output regardless of the current state|
|Reset||[BOOL]||Resetting the output regardless of the current state|
If there is a change of edge from 0->1 (rising edge) at the "Input" signal input, the "Output" signal output is set if it is in the Low state or reset if it is in the High state.

The STEP 7 Micro/WIN library as archive file
Copy the "logo_functions.exe" file into a separate directory and then start the file with a double-click. The STEP 7 Micro/WIN library is unpacked. You can then integrate the library, which can be used in version V18.104.22.168 and higher of STEP 7 Micro/WIN, into your S7-200 project.
- Information about inserting libraries in STEP 7 Micro/WIN is available in Entry ID: 16689345.
