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 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).
• When (d) is a bit device, data should be specified in order from lower bits.
Ex.
Operation result when (d) is a bit device
Operation error
