7.3 Access Control7.3.1 FB 48 - ACONTROL - Access controlWith this block a access control can be implemented. After getting a code from anexternal keypad, panel or RFID reader, the code is compared with a list. Depending onthe result, then the relative outputs are controlled.n The access codes are to be applied in a data block, which is specified by ACLBlock.Here you can also specify which outputs Access1...6 are to be controlled and how(pulse/static) are they controlled. With the data block up to 16 access codes can betreaded.n Via AccessCode1...4 the code of the corresponding input device is specified.n Via CheckCode1...4 the code is compared with the code in your data block ACLBlock.– If the access code in the data block exists, the corresponding outputs are con-trolled according to the specifications. With configured pulse output you canspecify the pulse duration with TimePulse.– If the access code does not exist in the data block, the output Error is set for theduration TimeError.n With an edge change 0-1 of CentralLock all the access codes are disabled. Here theoutput CentralLocked is set.n With an edge change 0-1 of CentralUnlock all the access codes are enabled and theoutput CentralLocked is reset.Parameter Declaration Data type DescriptionAccessCode1 INPUT STRING[16] Access code, e.g. from keypad.CheckCode1 INPUT BOOL With an edge change 0-1, the AccessCode1 iscompared with the access code in the data blockACLBlock.Default: 0AccessCode2 INPUT STRING[16] Access code, e.g. from panel.CheckCode2 INPUT BOOL With an edge change 0-1, the AccessCode2 iscompared with the access code in the data blockACLBlock.Default: 0AccessCode3 INPUT STRING[16] Access code, e.g. RFID reader.CheckCode3 INPUT BOOL With an edge change 0-1, the AccessCode3 iscompared with the access code in the data blockACLBlock.Default: 0AccessCode4 INPUT STRING[16] Access code, e.g. from an other systemCheckCode4 INPUT BOOL With an edge change 0-1, the AccessCode4 iscompared with the access code in the data blockACLBlock.Default: 0CentralLock INPUT BOOL With an edge change 0-1 all the access codes aredisabled.
