Handling timers as numeric devices
In timers, the output contact operating in accordance with the set value is used in some cases, and the present value
is used as numeric data for control in other cases.
The figures below show the structure of the timer present value registers. When a timer number is specified in an
operand of an applied instruction, the timer is handled as a device storing 16-bit or 32-bit data in the same way as data
registers.
1. Structure of timer present value register
1) 16-bit
2) 32-bit
2. Use examples in applied instructions
For the full use of timers as numeric devices, refer to the explanation of applied instructions later.
