6.9.1.3 Benefits of passive mode
• If safety-related communication will not be performed via the F 8627X, then safety-
related dummy variables need not be defined between the PES during configura-
tion.
• It is now possible to have simultaneously a safety-related communication (via AG
master F 8621A or a second F 8625/27) and non safety-related communication to a
HIMA OPC server in one PES since no more dummy variables are needed for com-
municating with the HIMA OPC server.
• An overload of the PC running the HIMA OPC server can be prevented in cases in
which the number of available communication partners is too small (e.g. due to fre-
quent token holding caused by the short token cycle).
6.9.1.4 Numbers of HIMA OPC server and determination of the node Id
• HIPRO-S mode (S1/7 "OFF"): Fixed to four HIMA OPC servers.
Node Ids of the HIMA OPC servers are 107 to 110.
• HIPRO-S-DIRECT mode (S1/7 "ON"):
Switches 2/6-8 set the number of HIMA OPC servers with which the F 8627X can
exchange BUSCOM variables.
A range of node Id's is available for the number of HIMA OPC servers selected via
switch 2 (see Table 14).
• The Node Id is required for configuring the HIMA OPC server (see manual "HIMA
OPC server 3.0 Rev. 2").

Note Hubs may not be used in Passive mode. Switches are recommended.
