Input and output are signals that are used to communicate between the PLC and external devices.

• Inputs are signals received by the PLC from sensors or other devices.

• Outputs are signals sent by the PLC to actuators or other devices.

• PLC processes the input signals and generates the output signals based on the program logic.

• Examples of inputs include switches, sensors, and analog signals.

• Examples of outputs include motors, valves, and alarms.

Yes, I have knowledge of servo drives.

• I have experience in programming and troubleshooting servo drives.

• I am familiar with different types of servo drives such as AC and DC servo drives.

• I have worked with servo motors and have knowledge of their operation and control.

• I have experience in integrating servo drives with PLCs and other automation systems.
