Consistency check In addition to the sample configuration chart 1, shown in Figure 5-36, other configura-
tion sheets may exist. The contents of any particular configuration sheet is compiled
by DIGSI
®
4 into a program and processed by the protective device. For CFC charts
developed by the user, syntactic correctness can be verified by clicking the menu
command &KDUW, and then &KHFN&RQVLVWHQF\. The consistency check will deter-
mine if the modules violate conventions of various run-time levels, or any of the prin-
ciples below.
Check of functional correctness must be performed manually.
The completed CFC chart can be saved via menu item &KDUW, and &ORVH. Likewise,
the CFC chart may be reopened and edited by clicking on &KDUW, selecting the appro-
priate chart, and clicking on 2SHQ.
Please be aware, certain limitations exist, because of memory space and processing
power. The limits listed in Table 5-6 are generally applicable. The limits given in Table
5-7 are relay-specific. These limits must not
be exceeded because adverse effects to
the protective functionality (e.g. slower trip times) would result.
Table 5-7 Maximum Number of Modules per Process Area for SIPROTEC
®
7SJ62
The limits are monitored by the DIGSI
®
4 operating program. When 100 % of the al-
lowed memory is used, DIGSI
®
4 issues a warning message. See Figure 5-37.
