### FB SIMPLE MERGER
*******************

![[Pasted image 20231105152011.png]]


This FB works with 2 motors on infeed and 1 motor on exit. Works with a passive flap on the exit that guide the bottle to the
one motor exit. The inputs/outputs are uint values as used on the standard with the FC20 / FC22. 

There are two channels SX/DX and each channel has first gate called A and a second gate called B. The trains are formed between the two
gates.

The logic by default gives priority to SX channel. This can be override by the IN_DXPriority input.

#### General IN signals:
* Auto mode
* Manual mode

#### The signals for each channel needed are: 
* Photocell Gate A
* Photocell Gate B
* Manual commands

#### The signal for the downstream:
* Photocell Outfeed: 0: Request 1:full

#### The outputs are for each channel:
* Open/Close Gate A
* Open/Close Gate B
* MotorFix1 : Slow
* MotorFix2 : Fast for takeout the train
* Alarms for the sensors

#### The main timers for the commissioning are:
* TON for photocells on gate A/B
* TON/TOFF for exit cone free
* TON Delay_MinimunExit_TON minimum time between consecutive trains
* Delay_Sx_SwitchToUnloadSpeed : Time to go high speed

#### Constante:
* MaxConsecutiveTrains : maximum number of consecutive trains from the same channel for priority
