AutoThrottle with servo

[BoeingNG]

Hi Les,

Interesting. I will give it a try.

Hi Les:
What you trying to say that we don´t need a relay to turn power servo off ?
How to send a 0 to servo bd to disc power... In other words how to do this in SIOC script..
Sorry I am not a Sioc expert ... Maybe John knows something.

Regards

Hi,
Sorry im no expert on sioc.Yes a 0 written to the servo will disconnect power.I was trying to get a Elevator trim indicator to work.So thought i would try it.When it has a zero there you can turn it by hand.Increase this to one and its locked.
If you want to try this,just go to sioc and hit the config button and find what variable you are using to send data to Servo.Open IOCP Console from SIOC and scroll to
this varaiable.Double click it and then enter 0 and hit send button.Firstly make sure
you have connected message showing.You should be able to turn the servo by hand.
I would give you code if i could but would have to check it out and at the moment cant manage it.There is probably people who can.Nico Kaan is an ace,he might pop up.
If you havnt had any luck,let us know and i will try an run some checks on some code.
Good Luck.

Hi Guys,

I have been off for a week or so and tried the "0" this morning. Yes it disconnects the power to the servo. I will tidy the SIOC code up and post it later on this evening for the Thrust Levers.

Basically, if the A/T LED is not lit, send 0 to to Thrust Servos.

OK, as promised.

Here is the SIOC code for Thrust Lever Engine 1 with Servo. This assumes your throttles etc works manually and is calibrated in Windows and or FSUIPC

Brief explaination
read offset for AT Armed in pmdg
write Throttle 1 servo (your connections and device may be different)
read offset for Thrust lever 1 in pmdg


Var 0026, name AT_Arm, Link FSUIPC_IN, Offset $62BD, Length 1 // Auto Thrust Armed (<75 not armed)
Var 0206, name TQ_Thr1_SV, Link USB_SERVOS, Device 3, Output 1, PosL 0, PosC 512, PosR 900
Var 0205, name TQ_Thr1_pmdg, Link FSUIPC_IN, Offset $088C, Length 2 // TQ PMDG Throttle 1
{
IF &AT_ARMD < 75 //(If A/T Disarmed)
{
&TQ_Thr1_SV = 0 //(Turn off Power to Servo)
}
ELSE //(Otherwise it is Armed and power the Servo)
{
IF &TQ_Thr1_pmdg > 0 //(If Thrust LEver 1 Offset is > than 0)
{
L0 = &TQ_Thr1_pmdg / 29 //(29 is the ratio of pmdg value to actual travel value in FSUIPC)
&TQ_Thr1_SV = L0 + 240 // (The 240 is the additional value added to line up the lever properly)
}
IF &TQ_Thr1_pmdg < 0 //(If the THrust lever 1 offset drops below 0)
{
L0 = &TQ_Thr2_pmdg + 1024 // (Settle the lever at idle - this bit needs more work)
&TQ_Thr1_SV = L0
}
IF &TQ_Thr1_pmdg = 0 //(Thrust lever 1 offset = 0)
{
L0 = 50
&TQ_Thr1_SV = L0 // Sets postition of lever to 50 (idle position)
}
}
}



Hope this helps
Regards,
John

Hi John:

Do you have the SIOC script for using in Auto Throttle with Sevo cutting power by Relay .

Thanks
