An overload (OVD) message on an MG 1000E indicates a network loop is
disabled and that all connections on the loop are disabled. The network
loop number corresponds to a specific card number in the MG 1000E.
System messages can also indicate that one or more cards is defective or
disabled without producing an OVD message. In either case, look up all
system messages in Software Input/Output Reference – System Messages
