OSx Station Basics1-8 SIMATIC PCS 7 OSx 4.1.2 Operator
PCS 7 OSx Stations (continued)
The architecture for a multiple-station configuration is shown in Figure 1-3.
If you are using only Series 505 and/or S5 controllers, you can connect up to
16 OSx stations to the network.
S7-417, S7-416, and S7-414 controllers limit the number of hosts that can
sign on for the S7 messaging services, Alarm_S and Alarm_8. OSx uses
these services for RBE messages. The S7-417 controller and the original
releases of S7-416 allow up to eight OSx stations, and the original releases
of S7-414 controllers allow up to four stations.
