Figure 154: Overview of the apparatus control functions
Features in the apparatus control function:
• Operation of primary apparatuses
• Select-Execute principle to give high security
• Selection and reservation function to prevent simultaneous operation
• Selection and supervision of operator place
• Command supervision
• Block/deblock of operation
• Block/deblock of updating of position indications
• Substitution of position indications
• Overriding of interlocking functions
• Overriding of synchrocheck
• Pole discordance supervision
• Operation counter
• Suppression of mid position
The apparatus control function is realized by means of a number of function blocks
designated:
• Switch controller SCSWI
• Circuit breaker SXCBR
• Circuit switch SXSWI
• Bay control QCBAY
• Bay reserve QCRSV
• Reservation input RESIN
• Local remote LOCREM
• Local remote control LOCREMCTRL
The signal flow between the function blocks is shown in Figure 155. To realize the reservation
function, the function blocks Reservation input (RESIN) and Bay reserve (QCRSV) also are
included in the apparatus control function. The application description for all these functions
can be found below. The function SCILO in the Figure below is the logical node for interlocking.
