Executing programs in a basic S4/S4c externally?

iinjlv01

Hello,





I must execute programs without control pendant, and the controller is
a basic and "naked" S4/S4c (no WebWare, no FactoryWare/RAP, no Advanced
Options, no DSQs... only floppy and RS232/Ethernet ports) I could
activate the FTP server and put files from a PC in the controller HD,
but now I want use a PC/PLC/DIY electronic board to load and execute
programs saved in FTP. How can I? I think some absurd ideas:


1A?) Use RS232/RJ45 ports, but without FactoryWare/RAP I don't have any clue about


2A?) Use PLC + DeviceNet/CAN and put Robot in Slave Mode, but i can't
find information about configuration of this mode for S4/S4c and I
don't know if i need extra hardware/firmware


3A?) Connect a custom electronic tinkermachine in control pendant port
and send bytes to select and execute program, but i can't find the
protocol specs





Can somebody help me with this problem? Links or info will be welcome





Thank you and sorry my badde english please!

Hi, i am not shure that i understand your problem, you don't have a teachpendant?

Hello Rookie,

i am so sorry, but i am still learning english and i am a bit unintelligible sometimes, i will try hard this time! I have a teachpendant, of course, but i don't have RAP option or soft for CAN2/Slave Mode option, no WebWare Server or SDK... with a S3, it exists RS232 commands to execute programs loaded in controller, with S5, Slave Mode option (PLC control, i think) is a "default option" and you don't need pay more money for that... And S4/S4c? Well, this system has a RS232 port, a ethernet port but you can't use them to execute a programm without an addon, that cost >3000?,?, for example WebWare (perhaps i am wrong and you can correct me... if i am wrong, i will be really happy!) So, I think... "I have to execute a program with a PC, the teachpendant sends a signal and the program begins, i can send the same signal using a DIY-junkpiece connected to the PC (a.k.a microcontroller + serial or USB or...) and it works..." Ok, but i have a problem, i don't know the protocol of the signal (CAN maybe?)... It is just a crazy idea and if you know a better low cost system to make this and you can give me some info about, thank you very much!... if you don't, thank you very much for your reply!

Hello forum,

i talked with an ABB's technician and he says me about LoadStart system parameter...and that command it's a partial solution to my problem. I have configure one Digital Input (DI) to "LoadStart" the AUTOLOAD.PRG. After I rewrite the program in controller's FTP with STOP in the last line (because it executes prg in default mode "continuous"... clues to change default value to "cycle"?) every time that I need run one different. Finally I active DI with a relay which can controlled by my PC. Ok, it's not very elegant, but it works for less than 20 euros (12F PIC+MAX232+RELAY)!
