Plc Device Data Display - Mitsubishi Electric EZMotion-NC E68 Series Operation Manual

7.4.2 PLC Device Data Display

Monitor display of state signals and register data used with PLC can be made.
When the PLC-I/F screen is first selected, 8-byte input/output data starting at device X0000 is
displayed in the left block; 8-byte input/output data starting at device Y0000 is displayed in the right

The screen always monitor-displays the PLC signal state. When PLC signal changes, the displayed

delayed or a response to a very short signal change may not be made.
