Figure 54: Example of interaction between GNRLCSWI, SYNCRSYN
(synchrocheck and synchronizing function) and DAXCBR functions
The present status information of the apparatus, that is, open or closed or intermediate
stage is available to GNRLCSWI function from the switch function DAXCBR/
DAXSWI via XPOS input. The XPOS input of GNRLCSWI is connected to XPOS
output of DAXCBR/DAXSWI. The same information is also available at the
GNRLCSWI binary outputs at OPENPOS, INTERMPOS, and CLOSEPOS. The
output POSITION indicates the same information in integer form.
The EXE_OP and EXE_CL are the execution command for opening and closing
operation. Once all the required conditions for an opening or closing operation are
fulfilled, GNRLCSWI generates the execution command; these outputs are directly
connected to OPEN and CLOSE inputs of the switch function DAXCBR/DAXSWI.
When an apparatus is selected either from LHMI or by L_SEL input, output
SELECTED is activated, indicating the selection has been made and now waiting for
the opening or closing command. The blocking of execution of command if any by
QCCBAY function is reflected at CMD_BLKD output.
Depending on the error that occurs during the command sequence, the error signal is
set with a value. An output L_CAUSE on the function block indicates the latest value
of error during the command.

Circuit breaker/Circuit switch

The functional block, DAXCBR acts as an interface module for circuit breaker and
DAXSWI acts as an interface module for disconnectors and earth-switch. The binary
input information indicating the status of the apparatus is connected to POSOPEN and
POSCLOSE input of DAXCBR/DAXSWI function. In case of circuit breaker with
truck arrangement, the truck positions are also connected to DAXCBR function at
TRUCK_OPEN and TRUCK_CLOSE inputs. The status is also available at binary
output OPENPOS and CLOSEPOS output of DAXCBR/DAXSWI function. In case
