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 multiply 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).
• When (d) is a bit device, only the lower 32 bits of the operation result are stored. If the upper 32 bits of the operation result
are required, temporarily store the result in a word device, and transfer the data stored in (d)+2 and (d)+3 to the specified
bit devices.
Ex.
Operation result when (d) is a bit device
Operation error
There is no operation error.
