6.2 Commissioning
6.2.6 Dynamic IP and naming
With DCP (Discovery and Configuration Protocol) the IP address and ’Name of station’
in the device can be changed on the fly, by the PLC. Therefore the IP address shown in
MacTalk is only the power up default, and may not be the actual used IP address after
the PLC has established communication.
Ifcheckingthe“Powerupwithblanknameofstation”(factory default) inMacTalkand
savetheconfigurationinflash,thentheMAC00‐EPx/ MIS/MILxxxxxxEPxx willalways
startupwithoutastationname.Thisenablesthepossibilityofhavingnewdeviceson
stock,andifneededexchangetheminthemachinewithoutany
setup,asthePLCcan
beprogrammedtoautomaticallyassigningthecorrectname,whenitfindsadevice
withoutname.
