DIV(P)(_U)
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 result in the device specified by (d).
*1 The DIV instruction is not supported by the ST language. Use DIV of the standard function.

■Applicable devices
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 division result in the device specified by (d).
• Two devices in total starting from the one specified by (d) are used to store the division result. Make sure that these two
devices are not used for another control.
