System role

This section explains what the product does and where it acts in the surrounding system.

Function
Controls direct push-button input and LED status indication for a SIMATIC control system.
System position
Sits between the operator controls, discrete I/O and the controller network in a machine panel.
Upstream / inputs
The operator presses the 32 keys, while the panel receives controller status through its digital I/O and PROFIBUS or MPI path.
Downstream / outputs
It sends key states to the control system and displays status through its 32 LEDs.
Limitations
Unknown: the installed project or program, field wiring, firmware, cabinet fit and physical condition of a particular 6AV3688-3ED13-0AX0 unit.
