9 Important Notes
9.1 Perm issible Installations
Software products that are not mandatory for the operation of PCS7 mus t not be installed in servers,
clients or multi-clients. This includes MS Office, for example. This shall prevent that the installation of
other software components (such as DLLs) has a detrimental influence on t he system behavior.
9.2 T ime in the Bus System
Time synchronization is mandatory in the bus system. Consistent m essage processing is not possible
otherwise. A PCS7/TM OS should be time master, the time of the other PCs should be synchronized
with the PCS7 tool DCS77 client.
9.3 Logical Connections
Creating logical connections with the same CS275 address is not perm itted. The name of a logical
connection must not contain any special character (including "_"). T his means that AS_103 is not per-
mitted.
9.4 ZKS Blocks
The access to ZKS blocks has not been implemented.
9.5 C Scripts
• General: We expressively want to point out again here that the general conventions of the pro-
gramming language C must be observed when scripts are employed. Fai lure to do so may cause
unpredictable reactions that can strongly affect proper operator comm unication and visualization.
• When connecting a graphical object with a scrip t only the value of the object is transferred. This
value will be signed “valid” independent of the state of the value.
• When dynamising the property “tagname “ of an O CX it should be taken care that this it not car-
ried out cyclically.
9.6 Quant ity Framework
When project images are configured in WinCC/TM, the capacity utilizati on of the bus system and of
the subordinate automation systems must be taken into consideration in addition to the specifications
of the permissible mixed quantity framework / see TELEPERM M aktuell 19 98/011/. A server may be
charged with max. 600 variables/ second.
9.7 PROGR AF AS+
