3.13 The function block TON2
3.13.1 Functional description
The FB TON2 behaves in the same way as the FB TON (see chapter 3.12) but is extended by a feature
which stores the current timer time value on the TwinSafe logic, so that the logic program can continue
running for the remaining time after start-up. In order to use this function, the Enable input must be set
during the rising edge at TonIn and the function block must be parameterized accordingly (Parameter:
Starts with remaining time = True).
