Guest glenncovington Posted June 9, 2004 Report Posted June 9, 2004 I have a system using a S7-318DP. I have purchased a Diagnostic Repeater and placed in the network to try and gain insight to problems we have with the network. I am having two problems with using the repeater, which most likely are related. 1. I cannot seem to get a network topology from the unit. I am using Step7 V5.2 SP1, but the Prepare Line Diagnostics button remains grayed out. 2. The OEM of the equipment did a terrible job of routing the Profibus cables, a lot of wasted length. With the repeater there is DP1, DP2, DP3. Can I split up the existing into seperate segments DP2, DP3, and if I can; does each segment have a terminating resistor for a total of 3 instead of the present 2? Any help is much appreciated. Quote
