TIA Portal
Totally Integrated Automation Portal
The TIA Portal is the key to the full performance capability of Totally Integrated Automation.
The software optimizes operating, machine and process sequences.
Time-delay interrupt
You can find relevant information under the entry "Interrupt, time-delay"
Time-of-day interrupt
You can find relevant information under the entry "Interrupt, Time-of-day"
Timer
Timers are components of the system memory of the CPU. The operating system
automatically updates the content of the "timer cells" asynchronously to the user program.
STEP 7 instructions define the precise function of the timer cell (for example on-delay) and
trigger its execution.
Update interrupt
You can find relevant information under the entry "Interrupt, Update "
User program
SIMATIC differentiates between the operating system of the CPU and user programs. The user
program contains all the instructions, declarations and data for signal processing that control
a plant or process. The user program is assigned to a programmable module, a CPU, for
example. Structuring into smaller unit is supported.
Value status
The value status is additional binary information of a digital input or output signal. The value
status is entered simultaneously with the process signal in the process image input and
provides information about the validity of the signal.
Warm restart
You can find relevant information under the entry "Restart"
