Problem- Background transfer by pmc problem

[kningzer]

Hello all

I am having a little pickle here =)

I have written a program for my operators to create work programs for some Fanuc 15MB machines.

The idea is to make it as simple as possible for them to use this. So i was thinking that i was going to let the program activate a signal into the machine and then let the pmc activate the "External read start signal" and read the newly created program into the machine by background.

So first i checked the BMI connection manual and discovered that the signal G32.1(EXRD) is the signal to read externally from pmc.

I have edited the pmc by Fapt ladder 3 and added the EXDR signal and just hooked this upto a pushbutton.

So in theory when i press the button i latch the EXRD signal and then the machine should read the program in the background.

It's here the problems start... Nothing happens at all. I can read and punch program in the foreground without any problems and i can use the I/O communications too.

But when trying to read by pmc signal, nothing happens..

I have tried to send with and without XON/XOFF, and with/without controllers..

Does anybody have a clue what is happening here?
The pmc is A PMC-NB, machine controller is a FANUC 15MB
