Hi guys I'm super new to PLCs and was hoping somebody could point me in the direction of a good tutorial or provide some guidance on sending variables between SIMATIC devices over profinet. I have the following setup: Hardware: 2 x LOGO8 PLCs with I/0 expansions, KTP400 basic HMI, 19" IPC477E HMI communicating over profinet Software: TIA.15.1 for HMI downloads (KTP400) / RT for 477E and Soft Comfort for Logo logic. Everything communicates fine on the network. I've written programs to control both LOGOs with both HMIs to control multiple solenoids and other I/O just using set/resetbit commands and read reed sensors via relays etc for digital feedback and events, which is fine but I'm struggling with how to pass variables between the HMIs and LOGOs. For instance, a great starting point would be to enter a variable into a I/O field in TIA which feeds into an on-delay block into soft comfort to delay turning on an output. This is as far as I've got (Just to get just to get the feel for it): Create a simple block on-dely function in soft comfort, added a I/O element in TIA and attached a VW address in the Tag Table but there's no effect in RT. (screenshots attached) Could somebody possibly shunt me in the right direction? Thanks loads! Attachmentforum help.zip (284 Downloads) |
