FB_MUL

Description Function Block

The FB_MUL function block is used to multiply the AnalogIn1 input with the AnalogIn2 input and pass the result to the AnalogOut output.

Then the AnalogOut output is set to 0 and the bError output is set to 1.

The FB_MUL function block is not supported by the EL6900.
