Starting ASUBs in spite of active read-in disable and/or IPO single block (SBL1)
To start ASUBs in spite of an active read-in disable:
DB21, ... DBX6.1 == 1 (read-in disable)
and/or IPO single block (SBL1), the following machine data must be parameterized:
• MD10702 $MN_IGNORE_SINGLEBLOCK_MASK (note prevention of single-block stop)
• MD11602 $MN_ASUP_START_MASK (ignore stop conditions for ASUBs)
• MD20116 $MC_IGNORE_INHIBIT_ASUP (execute interrupt program in spite of read-in
• MD20117 $MC_IGNORE_SINGLEBLOCK_ASUP (execute interrupt routine in single
Cross-mode Start of ASUBs
Requirements:
• Option: Cross-mode actions (Order no.: 6FC5 251-0AD04-0AA0)
• MD11602 $MN_ASUP_START_MASK, at least Bit 0 = 1
For error-free execution of the function, the following settings in particular must be noted:
• MD11600 $MN_BAG_MASK
• MD11604 $MN_ASUP_START_PRIO_LEVEL
• Interrupt assignment priority
Recommended settings:
• MD11600 $MN_BAG_MASK = H11
• MD11602 $MN_ASUP_START_MASK = H111
• MD11604 $MN_ASUP_START_PRIO_LEVEL = 7
