Get the system ID

lomeraniel

Is there any function in Netlinx Studio to obtain the own System ID number? I need that information for my program to compare the number with some others because I'm working with 60 masters together...

Thanks

The system variable SYSTEM_NUMBER is supposed to contain this, though I must admit I've never used it.

The system variable SYSTEM_NUMBER will give you the system number of the master the code is running.

IF(SYSTEM_NUMBER = 3)
{
  // do something if the system number is 3....
}

Another application

DEFINE_DEVICE
dvMaster = 0:1:0

DEFINE_VARIABLE
INTEGER nMySysNum = 3 // the system number the master should have

DEFINE_EVENT
DATA_EVENT[dvMaster]
{
  ONLINE:
  {
    IF(SYSTEM_NUMBER <> nMySysNum) // if the current system number differs
    {
      SET_SYSTEM_NUMBER(nMySysNum) // set the new system number
      REBOOT(dvMaster) // reboot the system to take effect
    }
  }
}

SYSTEM_NUMBER does give it to you. I use it all the time.
