Source The source denotes the origin of the information which the matrix receives for further
processing. Possible sources are:
− BI Binary Input,
− F Function key, which may serve to introduce a switching action,
− C CFC, i.e., message comes from user-definable logic,
− S System Interface.
Destination The destination indicates to which interface the information is forwarded. Possible
destinations are:
− BO Binary Output,
− LED LED display on the Device Front Panel,
− O Indication Buffers of the Device (Operational Indication Buffer, Sensitive
Ground Fault Indication Buffer (if available), Trip Log Buffer,
− S System Interface,
− C CFC, Information is processed by CFC Program of the User-definable Logic
− B Control Display (C), if an information is to be displayed in the Control Display
of the device), Default Display (D), if an information is to be displayed in the
Default Display of the device
− CM Control of switchgears, if a switchgears is to be indicated in the Control
Menu of the device
5.2.3 Control Commands for Switching Devices
Control commands are output indications which are specially configured for the
transmission of control signals to power plant switching devices (circuit breakers,
isolators, etc.). Once the type of a command has been established, DIGSI
®
4 reserves
a corresponding number of output relay contacts. For this, the corresponding output
relays are numbered consecutively. This must be observed when wiring the relays to
the corresponding power plant to be controlled.
Table 5-1 lists the most important command types as they are offered for the
configuration of the matrix (also refer to the paragraph “Binary Outputs for Switching
Devices” in Subsection 5.2.5). All double commands (with or without feedback) are
also available as transformer tap commands. The following Figures (from 5-5 to 5-13)
show timing diagrams, control settings, and the order of relay allocations for frequently
used command types.
