softMC as OPC UA Server

To enable softMC OPC UA you need:

• Install ipk or rpm  http://softmc.servotronix.com/wiki/File:opcua.zip#file with OPC UA to your softMC controller, if you do not have the file contact servotronix support
• Copy OPC_UA.LIB file to your softMC controller , if you do not have the file contact servotronix support
• Load it from the config.prg, see below
• Exctute it from autoexec.prg, see below

CONFIG.PRG

program

Print "system is running"

Sys.DoubleFormat = 1
 
Load opc_ua.lib

end program

AUTOEXEC.PRG

Program Continue

dim x as long

Load startprg.prg

while startprg.prg.state <> 10

    sleep 500

end while

Load IND4.prg

StartTask IND4.prg

x =stop_start_server ; restart OPC UA server

End Program
