pneumatics coding problem (or technical)

[wildabyss]

Isn't p1_sw_aux1 and p1_sw_aux2 the two buttons on the joy stick under the joy stick wheel?

But then why doesn't our code work?

We are using a double solenoid valve to control a cylinder; relay 1 (a spike) is connected to one end of the valve and relay 2(another spike) is connected to the other end of the valve (right? )

So the code goes:

relay1_fwd = p1_sw_aux1;
relay1_rev = 0;
relay2_fwd = p1_sw_aux2;
relay2_rev = 0;

The problem is that the spikes were orange while the circuit breaker was green. The pressure was all right for the cylinder to move (manually) but the joy stick control didn't seem to work at all...

One more thing, our pressure switch won't turn off when the pressure reaches 115 psi, when our code was "relay8_fwd = rc_dig_in18"
But when the code was "relay8_fwd = !rc_dig_in18", there was no pressure in the compressor!! What the...is going on????

What's wrong guys? NEED HELP!!!
