I/O Format
Input Format
The following commands can be input when the Controller is in Monitor or Run
mode.
STEP Signal
A one-time measurement is performed if the STEP signal is turned ON.
DI Signals
DI signals can input the following commands. After the command information
is set, allow at least 1 ms before turning ON DI7 (execution trigger). Signals
DI8 to DI15 are used only when units 31 and later are specified using the
model re-registration command.
(In the following table, 0 indicates the signal is OFF, and 1 indicates the signal
is ON. An asterisk indicates that the Controller does not read the bit status, so
the bit status can be either 0 or 1.)
• Model Re-registration Command
CHECK
Use I/O connectors DI0 to DI4 and DI8 to DI10 when specifying units 31 and
later.
Example: To Re-register Model for Unit 50

Unit number
Registers the models again for all regions for
the specified unit number. (When the through
display is being used, the models will be reg-
istered based on the last image that was
measured.)
(This command is enabled only if model posi-
tion compensation, circle position compensa-
tion, fine matching, pattern inspection,
rotation positioning, or ECM search unit num-
bers are specified. Other unit numbers will be
ignored if they are specified.) (See note.)
