PLC PROGRAMMING EXAMPLE
It is a three-axes machine (X, Y, Z) having a spindle with two speed ranges.
The PLC, besides controlling the 3 axes and the spindle, is in charge of lubricating the axes as well
as turning the coolant on and off.
CNC configuration
The PLC has 512 inputs and 512 outputs. Some of them, depending on the CNC configuration,
communicate with external devices.
Input I1 is the emergency input of the CNC and it must be supplied with 24 V, regardless of how it is
managed by the PLC program, as this signal is processed at all times by the CNC.
Output O1 is normally at 24V, high logic level, and it is set low, 0V, whenever an ALARM or an ERROR
occurs at the PLC output O1.
