Interlock Blocks

Intlk02 - Interlock display with 2 input signals

Type + number: FB 1824

Family: Interlck

The block is used for the following applications:

• Standardized interlock with display

The block is used to calculate a standardized interlock that can be displayed on the OS. A maximum of 2 input signals can be supplied to the block. They are linked using selectable binary logic. The signal status of the output signal is also determined. You can assign an analog value with the signal status and unit to each input value for display in the faceplate.

The current state is displayed at the Out output parameter:

• Out = 0: Interlock

• Out = 1: "Good" state

Use the CFC editor to install the block in a cyclic interrupt OB (OB30 to OB38).

For the Intlk02 block, the Advanced Process Library contains templates for process tag types as examples with various application scenarios for this block.

Examples of process tag types:

• Dosing (DoseLean)

• Dosing with PA/FF devices (DoseLean_Fb)

• Two-speed motor (Motor2Speed)

• Reversing motor (MotorReversible)

• Reversing motor with controllable speed (MotorSpeedControlled)

• Two-way valve (Valve2Way)

• Motor valve (ValveMotor)

• Control valve (VlvAnL)

• Control value for PA/FF devices (ValveAnalog_Fb)
