Hello. Service utility always take additional load. You can read about this inSIMATIC TDC System- and communication configuring D7-SYS, chapter 3.13.2 'System load, response times'. Try to reduce the load of all CPU's of the problem rack. Try to use separate CP51M1 (separate network) for service purposes. Check all cables, switches, other network components.
