代码 380050: PROFIBUS/PROFINET: Multiple assignment of inputs on address %1
问题描述与安全警告
Siemens SINUMERIK 840D CNC 触发了严重的 PROFIBUS/PROFINET: Multiple assignment of inputs on address %1 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 = Logical address Drives alarms Definitions: Multiple assignments of input data have been detect ed in the logical address space. Logical address: Base address of the address area defined several times Reaction: Channel not ready. NC Start disable in this channel. Interface signals are set. Alarm display. Remedy: The address partitioning should be checked as follows: Check for multiple assignments in the following machine data: - MD13050 $MN_DRIVE_LOGIC_ADDRESS[0] - MD13050 $MN_DRIVE_LOGIC_ADDRESS[n-1]: n = highest axis index on control system - MD12970 $MN_PLC_DIG_IN_LOGIC_ADDRESS, MD12971 $MN_PLC_DIG_IN_NUM: PLC address area for digital inputs - MD12978 $MN_PLC_ANA_IN_LOGIC_ADDRESS, MD12979 $MN_PLC_ANA_IN_NUM: PLC address area for analog inputs If no inconsistencies can be found in the parameters, compare these machine data with the configuration in SDB (STEP 7 project). In particular, chec k that the lengths configur ed for the individual slots do not result in area overlaps. When you find the c ause of the error, change the machine data and/or SDB. Program Continuation: Switch control OFF - ON.
