Switching outputs

With the CX7080, it is possible to switch output 1 automatically as soon as a certain counter value is reached. This enables fast processing without the PLC. A second output, output 2, can be switched via the PLC irrespective of the counter value.

Output 1 is switched or switched off respectively by the variables Switch on threshold value and Switch off threshold value:

If the value set under Switch on threshold value is reached, the output is switched.
If the value set under Switch off threshold value is reached, the output is switched off.

When counting downwards, the corresponding switching instruction is executed in reverse. If the value falls below the value set in Switch on threshold value, output 1 is switched off.

Proceed as follows:

1. Use the variable Switch on threshold value to specify a counter value at which the output should be switched.

2. Use the variable Switch off threshold value to specify a counter value at which the output should be switched off.

3. Then set the variable Enable output functions to True so that the settings are applied.

Only when the variable Enable output functions is set to True the function is enabled and the output is switched.

If the parameterized counter value from Switch on/off threshold is reached or exceeded, but the variable Enable output functions is not set, the switching order is not executed. The output is switched as soon as Enable output functions is set. Likewise, a subsequently activated counter value Switch on/off threshold affects the output immediately when the switching condition is fulfilled.
