6 BASIC INSTRUCTIONS
6.2 Arithmetic Operation Instructions
Subtracting 16-bit binary block data
BK-(P)(_U)
These instructions perform subtraction between the two 16-bit binary data blocks specified.
*1 The engineering tool with version "1.035M" or later supports the ST.
■Execution condition
Setting data
■Description, range, data type
*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.
■Applicable devices
