2.5.10 IN Direct input
■
How direct input (IN) works
● The reading for external input (X) is updated as a batch when input/output refresh is
executed, however if direct input (IN) is used, the reading for external input is updated when
the operation is executed.
● This is effective for controls that require a high-speed response.
● This is specified in the program with a combination of a slot number (S1, S2...) and a
corresponding address (IN0, IN1...).
● When using direct input (IN), it is necessary to select the setting to exclude this unit from the
target for I/O refresh when configuring the settings for the I/O map.
2.5.11 OT Direct output
■
How direct output (OT) works
● External output (Y) is output as a batch when input/output refresh is executed, however if
direct output (OT) is used, the operation result up until that time (ON/OFF) is output to the
external output when the operation is executed.
● This is effective for controls that require a high-speed response.
● This is specified in the program with a combination of a slot number (S1, S2...) and a
corresponding address (OT0, OT1...).
