Hi all, I need to execute a customized cycle, at the begining it's supposed to write a bit in the PLC memory and after doing the regular cycle, it has to read the bit and send it back to the HMI. I've been reading a lot of info but I cant find the way to access to a PLC bit without using the HMI, How would the header be to activate a bit in a DB? My hardware: - PC Host (connected through ethernet to the control) - Control sinumerik 840D - PCU50.3 (with HMI advanced) Any answer will be appreciated, Cheers!
