Table 22:Possible cause values from XLNPROXYCauseNoCause Description Conditions8 Blocked-by-Mode The BEH input is 5.2 Blocked-by-switching-hierarchy The LOC input indicates that only local commands areallowed for the breaker IED function.-24 Blocked-for-open-cmd The BLKOPN is active indicating that the switch isblocked for open commands.-25 Blocked-for-close-cmd The BLKCLS is active indicating that the switch isblocked for close commands.9 Blocked-by-process If the Blk input is connected and active indicating that theswitch is dynamically blocked. Or if the OPCAP input isconnected, it indicates that the operation capability of theswitch is not enough to perform the command.5 Position-reached Switch is already in the intended position.-31 Switch-not-start-moving Switch did not start moving within tStartMove.-32 Persistent-intermediate-state The switch stopped in intermediate state for longer thantIntermediate.-33 Switch-returned-to-init-pos Switch returned to the initial position.-34 Switch-in-bad-state Switch is in a bad position.-35 Not-expected-final-position Switch did not reach the expected final position.The OPCAP input and output are used for the CBOpCap data of aXCBR respectively SwOpCap for a XSWI. The interpretation forthe command following is controlled through the settingSwitchType.11.1.2 Interaction between modules M16626-3 v8A typical bay with apparatus control function consists of a combination of logicalnodes or functions that are described here:• The Switch controller (SCSWI) initializes all operations for one apparatus. Itis the command interface of the apparatus. It includes the position reporting aswell as the control of the position• The Circuit breaker (SXCBR) is the process interface to the circuit breaker forthe apparatus control function.• The Bay control (QCBAY) fulfils the bay-level functions for the apparatuses,such as operator place selection and blockings for the complete bay.• The Protection trip logic (SMPPTRC) connects the "trip" outputs of one ormore protection functions to a common "trip" to be transmitted to SXCBR.• The Autorecloser (SMBRREC) consists of the facilities to automatically closea tripped breaker with respect to a number of configurable conditions.• The logical node Interlocking (SCILO) provides the information to SCSWIwhether it is permitted to operate due to the switchyard topology.
