USB-7230/7250 Figure 3-3: USB-7230 Isolated Input Figure 3-4: USB-7250 Isolated Input 3.2 Change of State (COS) Detection COS (Change of State) refers to input state (logic level) changing from low to high or vice versa, wherein the COS detection circuit registers the edge of the level change. -
Page 42: Figure 3-5: Cos Detection Architecture
In the USB-7230/7250, the COS detection circuit is applied to all DI channels, with the channel(s) to enable COS detection select- able by software. When an enabled channel changes logic level, the COS detection circuit generates an interrupt request to the USB microcontroller, which, when detected, latches corresponding DI data into the COS latch register. -

PHOTO COUPLER n=0,1 Figure 3-7: USB-7230/7250 Optical Isolated Frequency/Event Counter The frequency counter base clock is 48MHz. The frequency coun- ter calculates base clocks occurring within a period (rising edge to rising edge or falling edge to falling edge) of the repetitive input signal, which is then converted to frequency value. -

By default, when enabled, the input channel ignores signal changes from one state to another when not remaining in the state for a pre-defined period. -
Page 46: Isolated Digital Output (Usb-7230 Only)
The DO output status is saved in the USB microcontroller and can be read back if necessary. The USB-7230 also features programmable power-up output sta- tus,allowing output in a known state when powered on. When the module is powered off (ejected from the USB port), all digital out- put reverts to OFF. -

Figure 3-12: Form C Relay... - Page 48 A relays have only NO (Normal Open) and COM (Common) con- tacts. When the control bit is high (1), the COM terminal and NO pole contact. If the control bit is low (0), no contact takes place. Current relay output status can be read back by software, and dur- ing normal power up, reset, and power down (ejection from USB port), the relay is low status.
