7 BASIC INSTRUCTIONS
7.2 Arithmetic Operation Instructions
SUB(P)(_U)
These instructions subtract the 16-bit binary data in the device specified by (s1) and the 16-bit binary data in the device
specified by (s2), and store the result in the device specified by (d).
*1 The SUB instruction is not supported by the ST language and the FBD/LD language. Use SUB of the standard function.
