Operand Description
(U) Start I/O number (first three digits in four-digit
hexadecimal representation) of a module
(s) Start device where control data is stored
(d1) Start device for storing the read data
(d2) Device that turns on for one scan upon completion of the
instruction
When the instruction completes with an error, (d2)+1
also turns on.
EN Execution condition
ENO Execution result
*1 When specifying setting data by using a label, define an array to secure enough operation area and specify an element of the array
label.
