This is the case whenthe state parameter DONE has the value "1".n Siemens S7-400 Communication– When a send operation is activated (rising edge at REQ) the data to be sent fromthe send area SD_i are copied from the user program. After the block call, youcan write to these areas without corrupting the current send data.8.2.13 FB 55 - IP_CONF - Progr. Communication Connections8.2.13.1 OverviewTo configure flexible communication connections, the FB 55 - IP_CONF allows the pro-gram controlled transfer of data blocks with configuration data for a CP.Please note that this block calls the FC or SFC 204 IP_CONF internally.These must not be overwritten! The direct call of an internal block leadsto errors in the corresponding instance DB!Configuration data for communication connections may be transferred to the CPU by theFB 55 called in the user program. The configuration DB may be loaded into the CP at anytime.Data consistencyPrincipleVIPA SPEED7 Network CommunicationEthernet Communication > FB 55 - IP_CONF - Progr.
