Simatic.Ax.SimpleControlModulesThe EncoderA counts the rising and falling edges of a binary signal.
The EncoderAB is similar to EnocderA but it counts the rising and falling edges of two 90 dregree phase shifted binary signals (SignalA and SignalB). So the counting direction is evaluated automatically.
| Evaluate() | Evaluate the SignalA for rising and falling edges and counts them |
| GetValue() : DINT | Returns the actual counter value |
| RelativeCount() | Retunrs the relative counter value |
| Reset | Reset the counter value to 0 |
| ResetRelative() | Reset the relative counter value to 0 |
| SetDirection(mode : CountMode) | Set the counting direction FORWARD or REVERSE |
| SetValue(value : DINT) | Set the actual counter value to value |

The Counter counts with the methods CountForward(increment : DINT) or CountReverse(decrement : DINT). The parameter increment or decrement is 1 by default.
Methods:
| Config(ll : DINT ul : DINT) | set the upper and lower limit |
| SetCounterValue(value : DINT) | Set the counterf value to value (default 0) |
| CounterValue() : DINT | Retunrs the actual counter value |
| CountForward(increment : DINT) | Count forward by increment (default 1) |
| CountReverse(decrement : DINT) | Count reverse by decrement (default 1) |
| UpperLimitReached() : BOOL | Returns TRUE when the counter value >= upper limit |
| LowerLimitReached() : BOOL | Returns TRUE when the counter value <= lower limit |
