DTDV (Data Divide)

Valid Devices

S1 (Source 1)

D1 (Destination 1)

For valid device address ranges, see "Device Addresses" on page 2-1.

When T (timer) or C (counter) is used as S1, the timer/counter current value (TC or CC) is displayed.

Destination device D1 uses 2 data registers starting with the device assigned by D1.

Since the DTDV instruction is executed in each scan while input is on, a pulse input from a SOTU or SOTD instruction should be used.

Valid Data Types

D (double word)

Example: DTDV

S1 → D1, D1+1

When input is on, the 16-bit binary data assigned by S1 is divided into upper and lower bytes. The

upper byte data is stored to the destination assigned by device D1. The lower byte data is stored to

the device next to D1.

Binary data to divide

Destination to store results

When a bit device such as I (input), Q (output), M (internal relay), or R (shift register) is assigned as the source,

16 points (word data) are used.

When a word device such as T (timer), C (counter), or D (data register) is assigned as the source or destination,

1 point (word data) is used.
