| - | Unipi Neuron and Unipi Axon programmable logic controllers, as well as Unipi Extension modules, feature digital inputs with counter functionality by default. Depending on the chosen model, you can have up to 36 counter inputs without the need to purchase any external modules. Counter inputs on the mentioned controllers and extensions can be used to detect pulses of up to 10 kHz frequency. When the maximum value of a counter (4 294 967 295) is exceeded, its value is reset. | + | By default, all Unipi Neuron and Unipi Axon controllers, as well as Unipi Extension modules, feature digital inputs with counter functionality able to detect pulses of up to 10 kHz frequency and only tens or hundreds of microseconds long. When the maximum value of a counter (4 294 967 295) is exceeded, its value is reset. |
| Counter inputs on Neuron PLCs will reset if the device’s power is disconnected. On Axon controllers and newer Extension xS11 and xS51 modules, the counter values are stored in memory and loaded during the next device startup. This feature prevents any loss of data due to loss of power. | Counter inputs on Neuron PLCs will reset if the device’s power is disconnected.
