Wiring:
• Are parallel cables wired correctly?
Please check if GATE signals are being recognized by the receiving side (such as the PLC) by
turning the GATE signal ON/OFF in the System - Communication - Parallel - Confirmation win-
dow.
Output setting:
• Is parallel judgement output or parallel data output set for the scene? Is an expression input for
parallel data output?
• GATE signals are not output unless these items are specified.
• Is [Output] set to ON in the layout setup?
Set whether to produce external outputs for each layout.
Timing:
• Are the parallel communication settings (output cycle and output time) set to a length sufficient for
the PLC to recognize?
• Could the System - Communication - Parallel output control be set to handshaking or synchroni-
zation output?
These settings influence the GATE output timing.
