6 BASIC INSTRUCTIONS
6.2 Arithmetic Operation Instructions
■
Applicable devices
• In safety programs executed by the Safety CPU, only the following safety devices and constants can be used.
Processing details
• These instructions divide the 16-bit binary data in the device specified by (s1) by the 16-bit binary data in the device
specified by (s2), and store the operation result in the device specified by (d).
• As the operation result, the quotient and remainder are stored in 32 bits. When a bit device is specified, the number of digit-
specified bits is used to store the quotient and remainder.
