Siemens 840D 61371 - Channel block: Product of column width and number of columns

Channel block: Product of column width and number of columns

The alarm is triggerd by the following cycles: CYCLE105. Remedy: Reduce the column width (_PROTFORM[4]) or number of columns (_PROTVAL[2.5]).

Safety

  • Refer to Siemens documentation
  • Ensure qualified technician performs repairs

Common Causes

  • Column width parameter (_PROTFORM[4]) set too large for the specified number of columns
  • Number of columns (_PROTVAL[2...5]) exceeds machine memory capacity when multiplied by column width
  • Cumulative data structure size exceeds available buffer memory in CYCLE105
  • Incorrect parameter values entered during cycle setup or previous job execution

Troubleshooting Steps

  1. 1Verify current values of _PROTFORM[4] (column width) and _PROTVAL[2...5] (number of columns) in the active program or parameter list
  2. 2Calculate the product of column width × number of columns and compare against machine documentation limits for CYCLE105
  3. 3Reduce column width (_PROTFORM[4]) incrementally and re-run CYCLE105 to determine maximum acceptable value
  4. 4If column width cannot be reduced, decrease the number of columns (_PROTVAL[2...5]) and verify cycle executes without alarm
  5. 5Review machine manual specifications for CYCLE105 memory constraints and confirm parameter values comply with documented limits
