Valid Devices
For valid device address ranges, see "Device Addresses" on page 2-1.
Special internal relays cannot be designated as D1.
When T (timer) or C (counter) is used as D1, the data is written in as a preset value (TP or CP) which can be 0 through 65,535.
Source device S1 uses 2 data registers starting with the device assigned by S1.
Since the DTCB 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
Example: DTCB
S1, S1+1 → D1
When input is on, the lower-byte data is displayed from 2 consecutive sources starting with device
assigned by S1 and combined to make 16-bit data. The lower byte data from the first source device
is moved to the upper byte of the destination assigned by device D1, and the lower byte data from
the next source device is moved to the lower byte of the destination.

W (word) X When a bit device such as I (input), Q (output), M (internal relay), or R (shift register) is assigned as the
destination, 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.
