代码 27220: PROFIsafe: Number of NCK F modules (%1) <> Number of S7 F modules (%2)
问题描述与安全警告
Siemens SINUMERIK 840D CNC 触发了严重的 PROFIsafe: Number of NCK F modules (%1) <> Number of S7 F modules (%2) 警报。需要由合格的操作员或维修技师立即处理,以防止在制造周期中对设备造成二次损坏或导致零件报废。在接触电气控制箱之前,请务必确保遵循标准安全和停机挂牌 (LOTO) 程序。
官方故障排除步骤
Parameters: %1 = Number of parameterized NCK F modules %2 = Number of parameterized S7 F modules Definitions: The number of F modules parameterized via the NCK machine data $MN_PROFISAFE_IN/OUT_ADDRESS is: - Greater than the number of PROFIBUS slaves in the S7 PROFIBUS configuration. - Smaller than the number of F modules in the S7 PROFIBUS configuration, - greater than the number of F modules kn own in the S7 PROFIBUS configuration. If alarm parameter %2 = 0, then none of the configured F modules were found in the S7 PROFIBUS configuration. In most cases, the reason for the alarm is an error in the parameterization of the PROFIsafe master address. Reaction: Mode group not ready. Channel not ready. NC Start disable in this channel. Interface signals are set. Alarm display. NC Stop on alarm. Remedy: Check the F parameterization in MD $MN_PROFISAFE_IN/OUT_ADDRESS. Check the F configuration in the S7 PROFIBUS configuration. Check the parameterized PROFIsafe master address in MD $MN_PROFISAFE_MASTER_ADDRESS and in the S7 PROFIBUS configuration. Program Continuation: Switch control OFF - ON.
