yes upper limit is 100^o but that's no problem for me to program the up tilt cycle.

the problem i have is whit the down tilt cycle.

the down tilt has to go in steps for example 7^o.

the step-size depends on de size of the product that's being harvested and must be adjustable.

it has to do a down cycle each time you push the button.

when it reaches the lower limit switch it must reset so you can start again whit a up tilt cycle.

ones it done a up tilt cycle it must first reach the lower limit switch before it is able to go up agian. 

for example box goes up to 100^o

down button is pushed so box goes to 100 - 7 = 93^o

down button is pushed again so box goes to 93 - 7 = 86^o

down button is pushed again so box goes to 86 - 7 = 79^o

this goes one till the lower limit switch is reached.

my normaal siemens technical support person is on holiday so ithink a ask it on the Industry Online Support Technical Forum.
