Add New Module Online

[Zoldyck 0]

Hi, I have a few questions regarding adding a second 1756 ENBT/A Ethernet card online. Recently, I tried adding the card, but I was greeted with a warning "creating new module online could affect running system". Is it safe to add Ethernet card online while the machine is running. I cannot afford to do a download, so what is the best way do without interrupting the system. Thanks

That is the generic message to make you stop and think before adding a new module. Yes, adding any new module online COULD affect the running system, but the risk is lower when adding a communication module. If it is a new ENBT card, your risk is really low. The main risk when adding used or previously-configured modules is when there could be a duplicate IP address. You can avoid this risk by NOT connecting the comm cable to the new card until AFTER you have verified it is properly configured.
