============================================================

Example

Ch 3Ch 5Ch 7

WAITM(99,3,5) WAITM(99,3,5) WAITM(99,5,7)

The wait markers in channels 3 and 5 mutually wait for each other and channel 7 only waits for channel

5. Therefore, channel 7 may continue when 5 and 7 have reached the wait marker, but channel 3 is

still far in front of the wait marker.

When it continues, channel 7 deletes its wait marker. When wait marker 99 is reached again, you can

no longer determine the behavior precisely.

============================================================

Reaction: Alarm display.

Remedy: In each wait marker, list all channels with which you want to synchronize, or suppress the alarm with

$MN_SUPPRESS_ALARM_MASK, bit 23.

============================================================

Sample solution A:

Ch 3Ch 5Ch 7

WAITM(99,3,5,7) WAITM(99,3,5,7) WAITM(99,3,5,7)

============================================================

Sample solution B:

Ch 3Ch 5Ch 7

WAITM(99,3,5) WAITM(99,3,5)

WAITM(88,5,7) WAITM(88,5,7)

============================================================

Sample solution C:

Ch 3Ch 5Ch 7

WAITM(88,5,7) WAITM(88,5,7)

WAITM(99,3,5) WAITM(99,3,5)

Program Con-

tinuation:

Clear alarm with the Delete key or NC START.

16950 Channel %1 search run with hold block

Parameters: %1 = channel ID

Definitions: Info alarm

The block search was not performed on the interruption block, but stopped shortly beforehand on

another block. This so-called "hold block" is generated by part program command IPTRLOCK, or

defined implicitly in MD 22680 AUTO_IPTR_LOCK. The purpose of this function to prevent block

searches from taking place in critical program areas (e.g. during hobbing operations). The alarm

therefore indicates that the search has stopped on another block rather than on the interrupted block.

This behavior is desired and the alarm serves only informational purposes.

Reaction: Alarm display.

Remedy: MD 11410 SUPPRESS_ALARM_MASK MD 22680 AUTO_IPTR_LOCK and NC command IPTR-

LOCK

Program Con-

tinuation:

Clear alarm with the Delete key or NC START.

16951 Channel %1 search run in a program section that cannot be searched

Parameters: %1 = channel ID

Definitions: The part programmer can use NC commands IPTRLOCK and IPTRUNLOCK to identify a program

section as "search-suppressed". Any search attempted in this program section is acknowledged with

alarm 16951. In other words: Activation of this alarm indicates that the operator has started a search

(type Serupro) for a search target located in a program area that must not be searched! This kind of

program area can also be defined implicitly with machine data 22680 AUTO_IPTR_LOCK.

Note:

The alarm cannot be generated until the simulation during the block search is finished. The alarm can-

not be displayed immediately a block search is started.

Reaction: NC Start disable in this channel.

Interface signals are set.

Alarm display.

NC Stop on alarm.

Remedy: MD 11410 SUPPRESS_ALARM_MASK, MD 22680 AUTO_IPTR_LOCK and NC command IPTR-

LOCK
