Alarm 12380

Siemens 12380 - Block maximum memory capacity reached

The data definitions in this block cannot be processed because the maximum available memory for creating the data has been filled, or because the data block cannot accommodate any further data. The alarm can also occur if several subroutine calls are executed in sequence and no block with an effect on the machine is generated (motion, dwell, M function) Control reaction: Correction block is reorganized. Interface signals are set. Alarm display.

Siemens 12380 - Block maximum memory capacity reached

Block maximum memory capacity reached

The data definitions in this block cannot be processed because the maximum available memory for creating the data has been filled, or because the data block cannot accommodate any further data. The alarm can also occur if several subroutine calls are executed in sequence and no block with an effect on the machine is generated (motion, dwell, M function) Control reaction: Correction block is reorganized. Interface signals are set. Alarm display.

Safety

  • Only qualified personnel should diagnose and clear control alarms; follow the machine builder's safety procedures and lockout/tagout where hardware work is required.

Common Causes

  • The data definitions in this block cannot be processed because the maximum available memory for creating the data has been filled, or because the data block cannot accommodate any further data.
  • The alarm can also occur if several subroutine calls are executed in sequence and no block with an effect on the machine is generated (motion, dwell, M function)

Troubleshooting Steps

  1. 1Please inform the authorized personnel/service department.
  2. 2Reduce the number of variables, reduce the size of arrays, or increase the capacity of the data management system.
  3. 3If new macro definitions are to be introduced -> Increase MD18160 $MN_MM_NUM_USER_MACROS - If new GUD definitions are to be introduced -> Check MD18150 $MN_MM_GUD_VALUES_MEM, MD18130 $MN_MM_NUM_GUD_NAMES_CHAN, MD18120 $MN_MM_NUM_GUD_NAMES_NCK - If the error occurs while executing an NC program with LUD definitions or when using cycle programs (the parameters count as LUD variable of the cycle program), the following machine data must be checked: MD28040 $MC_MM_LUD_VALUES_MEM, MD18242 $MN_MM_MAX_SIZE_OF_LUD_VALUE, MD18260 $MN_MM_LUD_HASH_TABLE_SIZE, MD28020 $MC_MM_NUM_LUD_NAMES_TOTAL, MD28010 $MC_MM_NUM_REORG_LUD_MODULES
  4. 4Clear alarm with NC START or RESET key and continue the program
