5.5.4 Direct Input String (INS)
( 1 ) Operation
The INS instruction is executed in user programs to input data independently from the I/O batch processing that is per-
formed by the system at the start of the high-speed and low-speed scans. When the INS instruction is executed, the
inputs from the specified Module are processed according to the settings in a parameter table. The next instruction is
not executed until input processing is completed.
The following Modules can be specified.
• CPU Module (IO)
• LIO-01/02 Module (LIO)
• LIO-04/05 Module (LIO32)
• LIO-06 Module (MIXIO)
• AI-01 Module (AI)

INS instruction
Normally, the outputs and inputs
are processed at once for each
Module at the start of the
high-speed and low-speed scans.
These inputs are input from the Module
specified in the INS instruction, separately
from the batch inputs. Processing of the
drawings stops until the inputs are processed.
