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 32-bit binary data in the device specified by (s1) by the 32-bit binary data in the device
specified by (s2), and store the operation result in the device specified by (d).
• As the operation result when a word device is specified, the quotient and remainder are stored in 64 bits. The quotient is
stored in lower 32 bits, and the remainder is stored in upper 32 bits. When a bit device is specified, only quotient is stored in
32 bits.
