This assumes you have ENI File (EtherCAT.xml) in the same folder as the RMP and RMPNetwork files. Check NetworkStateGet() and, if errors, LastNetworkStartErrorGet(), NetworkLogMessageCountGet to determine the result of starting the network. This method can take several seconds to execute. After starting, if the state is operational, some overloads internally call Refresh() so all RapidCode objects must be recreated.
