Siemens 14070 - Block memory for variables not sufficient for subroutine call

A called subroutine cannot be processed (opened), either because the internal data memory to be created for general purposes is not large enough, or because the available memory for the local program variables is too small. The alarm can only occur in MDI mode Control reaction: Interpreter stop NC Start disable in this channel. Interface signals are set. Alarm display.

Siemens 14070 - Block memory for variables not sufficient for subroutine call

Block memory for variables not sufficient for subroutine call

A called subroutine cannot be processed (opened), either because the internal data memory to be created for general purposes is not large enough, or because the available memory for the local program variables is too small. The alarm can only occur in MDI mode Control reaction: Interpreter stop NC Start disable in this channel. 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

  • A called subroutine cannot be processed (opened), either because the internal data memory to be created for general purposes is not large enough, or because the available memory for the local program variables is too small.
  • The alarm can only occur in MDI mode

Troubleshooting Steps

  1. 1Analyze the part program section: 1.
  2. 2Has the most useful data type always been selected in the variable definitions? (For example REAL for data bits is poor; BOOL would be better) 2.
  3. 3Can local variables be replaced by global variables?
  4. 4Clear alarm with the RESET key. Restart part program
