I'm not familiar with PLC's but they should at the very least have pins that can set or clear bits. You can connect these pins to parallel port pins. Different bits can be predetermined commands, positions or movement. If the PLC has Modbus or some sort of serial port, this can be used for non-realtime movements and commands. Modbus is common for connecting VFD's. Search the wiki for "Modbus" and "VFD". > I have entered the TOOL_CHANGE_POSITION and TOOL_CHANGE_QUILL_UP in the INI > file and in the EMCIO section.
