I have a process that we are installing an AB SmartGuard 600 Safety PLC on. I am trying to give the Safety PLC its IP address and I cannot get it to take the configuration. Every time that I try to apply the change I get a fault telling me that the possible causes of failure are loss of power, loss of communications, the PLC is busy, etc. I have checked all of these but I cannot find any issues. I have put the controller in program, the safety PLC in idle mode. I have tried to configure the address from the AB BOOTP utility and nothing seems to work. Has anyone else had this issue or know what it is that I am doing wrong? Thanks in advance!
