Roller door... next phase

[L D[AR2P#0.0]]

Next phase is to use a global DB to specify which I/O to use for the roller door.

Start with InPEC - move InPEC boolean from the input section to the stat section. Add two more inputs called iInPECByte and iInPECBit both of type integer (this is for ease of monitoring)

Create a DB (say DB100) with an array[1..3] of structures called DoorConfig containing iInPECByte and iInPECBit

Update the calls to the doors using the byte/bit numbers from the DB

Not 100% sure on this.. this is what I have done, but do I do this for each?

"struct" goes in the empty box, then the byte/bit definitions of type int

Then switch to data view to show the array in all its glory.

db as follows, NB you have to delete the default initial value/comment:

Why is mine begin gay??

Click in the comment section of the last declaration then hit return to enter another declaration.

How does it do that.. Definately need to do more reading on this. DB100 complete

Start with InPEC - move InPEC boolean from the input section to the stat section.

When I move InPEC from input to stat, dont I loose it on the FB call..?

That's the point - you are not going to pass the input as a bool anymore, you are passing the address of the input via the byte & bit number instead.

Read post #1 again.

Ummm... Gonna have to think about this one, I know I've got to use pointers some how

Morning, been reading this morning and I think, I know roughly how to complete this using something along the lines of "DB3".DBX2 for example the part that is throwing me is in our array we are using two seperate locations one for the input byte and one for the bit. Im not sure how to combine them in the call? This doesnt mean Im giving up though.

Just had an idea could I use this format maybe, dont have access to simatic at work so cant check it?

P#<area><byte>.P#<bit>

.... Add two more inputs called iInPECByte and iInPECBit both of type integer...

You are going to pass two integers to the door FB, they will be combined inside the FB to form the inidrect address and access the actual input.

Arrrhhh god dam... I know where I've gone wrong, for someone reason when I modified fb2 I assumed the new parameters iInPecBtye and iInPecBit would already be there when I called the FB. Thank you for being patient with me
