Supported platforms: CODESYS 2.3, CODESYS 3.5
This ramp FB can be used when a fully linear ramp is required. Ascend and descend speeds depend on the adjusted ramp parameters.
Ramp parameters are defined as ms, i.e. how many milliseconds it takes to ramp from 0 to 32767.
The FB takes care of ascending and descending ramps.
When i_Enable input falls, the output is immediately set to zero without a ramp.
