If it is in the Codesys programming software you can see if you are online down in the right hand corner of you screen.
If it is using fx a Modbus RTU connection you need to program a heart beat.
If you need to run a program fro a Sd card take a look at the pdf attached. Chapter 13.2.3 for loading and 13.2.4 for storing.
You need to go through a series of drills. But first of all the INI file on the card has to be changed:
If you insert the SD card into the AC500 when the CPU is in RUN mode, the user program is not loaded independent of the settings for the parameters "FunctionOfCard" (bit 0=1) and "UserProgram" (=1). Thus, the function "Load user program" can be deactivated with the PLC-Browser command "sdfunc 0" even if no PC card reader is available.
