Valid Devices
Device
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. T (timer) or C (counter) is used as D1, and the
data is written in as a current value (TP or CP).
Since the TCCST 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
W (word) X
I (integer) —
D (double word) X
L (long) —
F (float) —
Example: TCCST
When input I2 is turned on, 99,998 is written to the current value of counter C23.

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) or 32 points (double-word data) are used. When repeat is assigned for a bit device, the
quantity of device bits increases in 16- or 32-point increments.
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) or 2 points (double-word data) are used. When repeat is assigned for a word device, the
quantity of device words increases in 1- or 2-point increments.

When input is on, 16- or 32-bit data assigned by S1 is displayed and stored to the
current value of device assigned by D1.
