Content	204Functional Example No. AS-FE-I-003-V10-EN Ex. No. The acknowledgement for the enable is given at the input ACK_NEC depending on the parameters: ■For ACK_NEC = 0 an automatic acknowledgement is given (as implemented in this example). ■For ACK_NEC = 1 an enable requires acknowledging ACK at the input by means of a rising edge. In order for the F application block to recognize whether the inputs IN1 and IN2 are only 0 due to a passivation of the re- spective F-periphery, you must supply the inputs QBAD_IN1 and QBAD_IN2 with the variable QBAD of the respective F pe- riphery DB. This prevents for example that for a passivation of the F-periphery the safety door must be completely opened prior to acknowledgement. Warning! The parameterization of the variables ACK_NEC=0 is only permitted, if an automatic restart of the respec- tive process is excluded otherwise. Should you supplement the example by means of a manual acknowledgement, please note the following: Note For safety door applications, the acknowledge signal must be read via a failsafe input module (F-DI), if it is an accessible hazardous area. For a non-accessible hazard- ous area, the acknowledge signal can also be read via a standard input module. The F-application module supports the requirements accord- ing to EN954-1 and EN 1088. After restarting the F system, the enable signal Q is reset to 0 . The acknowledgement for the enable is given at the input OPEN_NEC and ACK_NEC depending on the parameters: ■For OPEN_NEC = 0 an automatic acknowledge is given independent of ACK_NEC, as soon as both inputs IN1 and IN2 have the signal status 1 for the first time after reinte- gration of the respective F periphery (safety door is closed). In this example this variant has not been activated. ■For OPEN_NEC = 1 or if at least on of both inputs IN1 and IN2 have the signal status 0 even after reintegration of the respective periphery, an automatic acknowledgement is given depending on ACK_NEC, or the enable requires acknowledging ACK at the input by means of a rising edge. Prior to acknowledgement both inputs IN1 and IN2 must have had the signal status 0 (safety door completely opened) and subsequently signal status 1 (safety door closed). Warning! The parameterization of the variables OPEN_NEC=0 is only permitted, if an automatic restart of the re- spective process is excluded otherwise. At the output DIAG a non-failsafe information on occurred er- rors is provided for service purposes. You can read it out via HMI systems or if necessary evaluate them in your standard user program. Note The safety program does not allow accessing the output DIAG! FB COORDINATION (FB1, DB1) After processing the FB 217, processing is continued in FB 1: Network 2 The machine must only start at valid enable from FB 217 (#RE- LEASE= 1 ) and the start request ( COND1 = 1 ) from the standard user program. Additionally the tumbler (E_MAGNET) must be monitored (see Network 3 below). The machine stops by a failure locking. Network 3 B H * + - 7- . . : - ) $#-3 ) B GH H + )- $(- ) ) *2:) . : - 3
