POS : Address Positive Edge Detection
| Parameter | Data Type | Memory Area | Description |
| <address1> | BOOL | I, Q, M, D, L | Signal to be checked for a positive (rising) edge. |
| M_BIT | BOOL | Q, M, D | The M_BIT address specifies the edge memory bit used to store the previous signal state of POS. You should only use the process image input area I for the M_BIT when no input module is already using this address. |
| Q | BOOL | I, Q, M, D, L | One-shot output. |
Description
The Address Positive Edge Detection instruction compares the signal state of
<address1> with the signal state of the previous signal check that is stored in the parameter M_BIT. If there has been a change from 0 to 1, output Q has the
value 1, in all other cases it has the value 0.
