FB_Gain (Function Block)

Scales the input signal by a fixed gain.

A value greater than 1 amplifies the signal. A value between 0 and 1 attenuates it. A negative value inverts and scales. A value of 0 holds the output at zero.

Gain

Type: LREAL

Gets or sets the scaling factor.

A value greater than 1 amplifies the signal. A value between 0 and 1 attenuates it. A value of -1 inverts the signal. A value of 0 holds the output at zero.

Inputs

Name	Type	Description
`bInitRetains`	`BOOL`	if TRUE, the retain variables are initialized (warm start / cold start)
`bInCopyCode`	`BOOL`	if TRUE, the instance afterwards gets moved into the copy code (online change)
`fGain`	`LREAL`	Factor the input is scaled by.

Run
