■Descriptions, ranges, and data types
Operand Description
*1
(U) Dummy (Input the character string ['U0'].)
(s1) Connection number
(s2) Head device number for specifying the control data
(d1) Head device number for storing the receive data
(d2) Head device number which turns ON when the execution of
the instruction is completed and remains ON for 1 scan.
If the instruction is completed with an error, (d2)+1 is also
turned on.
