Note If the time is set to 0 ms, there will still be an ON delay time of 20 s max. and
Note Immediate refreshing will be performed for output bits allocated to Basic I/O
The default value for input response times is 8 ms and the setting range is 0 to
32 ms.
an OFF delay time of 300 s due to delays caused by internal elements.
A bit in the I/O Area is called an output bit when it is allocated to an Output
Unit. The ON/OFF status of an output bits are output to devices such as actu-
ators. There are two ways for the status of output bits to be refreshed to an
Output Unit: normal I/O refreshing and IORF(097) refreshing.
The status of output bits are output to external devices once each cycle after
program execution.
In the following example, CIO 000201 is allocated to an actuator, an external
device connected to an output terminal of an Output Unit. The ON/OFF status
of CIO 000201 is output to that actuator once each cycle.
When the immediate refreshing variation of an instruction is specified by
inputting an exclamation point just before the instruction, and the instruction’s
operand is an output bit or word, the content of the word containing the bit or
the word itself will be output just after the instruction is executed. This immedi-
ate refreshing is performed in addition to the normal I/O refreshing performed
once each cycle.
Units only (excluding C200H Group-2 High-density I/O Units and Basic I/O
Units mounted in Remote I/O Slave Racks), not High-density I/O Units which
are Special I/O Units.
1. Bit Operand
Just after the instruction is executed, the ON/OFF status of the 16 I/O
points allocated to the word containing the specified bit will be output to the
output device(s).
