Abstract: A logic circuitry package for a replaceable print apparatus component includes an interface to communicate with a print apparatus logic circuit, and a logic circuit having a communication address to communicate with the print apparatus logic circuit. The logic circuit is configured to detect, via the interface, communications that include an other communication address. The logic circuit is configured to respond, via the interface, to a command series directed to the logic circuit that include the communication address of the logic circuit, based on the detected communications.

Abstract: A logic circuitry package for a replaceable print apparatus component includes an interface to communicate with a print apparatus logic circuit and at least one logic circuit to transmit, via the interface, a limit parameter and a count threshold parameter. The logic circuit is to receive, via the interface, initial requests to read sensor IDs with the component connected to the apparatus and the apparatus not pneumatically actuating the component. The logic circuit is to transmit, via the interface, a resting state digital value in response to each initial request. The logic circuit is to receive, via the interface, further requests to read the sensor IDs with the component connected to the apparatus and the apparatus pneumatically actuating the component. The logic circuit is to transmit, via the interface, a further digital value in response to each further request.

Abstract: A logic circuitry package for a replaceable print apparatus component includes an interface to communicate with a print apparatus logic circuit, and at least one logic circuit to receive, via the interface, requests corresponding to different sensor IDs with the component connected to the apparatus. The logic circuit is to transmit, via the interface, a digital value in response to each request. The digital values corresponding to the different sensor IDs are distinct.

Abstract: A logic circuitry package for a replaceable print apparatus component includes an interface to communicate with a print apparatus logic circuit, and at least one logic circuit to transmit, via the interface, a sensor ID parameter and a limit parameter, the sensor ID parameter indicating a first sensor ID. The logic circuit is to receive, via the interface, a first request corresponding to the first sensor ID with the component connected to the apparatus and the apparatus not pneumatically actuating the component. The logic circuit is to transmit, via the interface, a first digital value in response to the first request. The logic circuit is to receive, via the interface, a second request corresponding to the first sensor ID with the component connected to the apparatus and the apparatus pneumatically actuating the component. The logic circuit is to transmit, via the interface, a second digital value in response to the second request. A difference between the first digital value and the second digital value is greater than the limit parameter.
