Beckhoff Automation ie1502

The counter module has two fast counters running at up to 100?kHz. It counts binary pulses and transmits the counter state to the higher-level automation unit. The up/down input allows the counters to be switched between upwards and downwards counting (in 32?bits). The gate signals (gate inputs) allow the counters to be triggered: Depending on the level at the gate input, the counting function is halted or enabled. The outputs can be switched according to the counter state, and can therefore be used as fast control signals for field devices. From the controller it is possible to set the counter state, to start or halt the counter function, and to set the outputs. The signal state of the inputs and outputs is indicated by light emitting diodes.
