Note
• When the input command is not received correctly, the ERROR signal turns ON.
• Acquisition is difficult because the amount of time during which the BUSY signal is OFF during a continuous
measurement for a parallel command is extremely short (1 ms or less). Get the OR signal when the GATE signal
turns ON after adding the parallel judgement output at the end of the flow.
Scene/Scene Group Switch
Scenes and scene groups are changed as follows.
When the number of the desired scene or scene group is set in DI0 to DI6 and DI7 is turned ON, the scene or
scene group changes to that set in DI0 to DI6.
