26240 Channel %1 block %2: The protection area indicated in $NP_ADD[%3] is
linked with a kinematic chain
Parameters: %1 = Channel number
%2 = Block number
%3 = Index of protection area element
Definitions: Protection areas added to an existing protection area via $NP_ADD[...], must not be linked to a
kinematic chain, e.g. $NP_CHAIN_NAME[...] and $NP_CHAIN_ELMEM[...] must be empty.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Enter in $NP_ADD[...] a protection area not linked with a kinematic chain or delete the reference to a
kinematic
chain in the protection area to be added or delete the entry
in $NP_ADD[...].
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
26242 Channel %1 block %2: Name of the kinematic chain in
$NP_CHAIN_NAME[%3] not defined
Parameters: %1 = Channel number
%2 = Block number
%3 = Index of protection area
Definitions: The name of the element of a kinematic chain was indicated in the protection area in
$NP_CHAIN_ELEM[...]. In this case, it is mandatory to indicate the name itself of the kinematic chain
in $NP_CHAIN_NAME[...].
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Indicate in $NP_CHAIN_NAME[...] the name of a kinematic chain or delete the entry in
$NP_CHAIN_ELEM[...].
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
26244 Channel %1 block %2: Protection area %3, referred to in $NP_ADD[%4],
is already contained in the definition chain
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Index of protection area
%4 = Index of protection area element
Definitions: A closed definition chain was found, i.e. a protection area element contains the protection area of
which it is a part.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Change definition of the protection area or delete protection area.
Program Clear alarm with NC START or RESET key and continue the program.
