16960 Channel %1 action %2<ALNX> prohibited during EXECUTE PROGRAM
AREA.
Parameters: %1 = Channel number
%2 = Action number/action name
Definitions: The function (2nd parameter) must not be activated during EXECUTE PROGRAM AREA.
Reaction: Alarm display.
Remedy: Wait for end of program area EXECUTE.
Program Clear alarm with the Delete key or NC START.
Continuation:
16961 Channel %1 action %2<ALNX> prohibited during syntax check.
Parameters: %1 = Channel number
%2 = Action number/action name
Definitions: The function (2nd parameter) must not be activated during the syntax check.
Comment: The syntax check is served by the following PI services:
_N_CHKSEL _N_CHKRUN _N_CHKABO

Continuation:
16962 Channel %1 NCK computing time reduced, start is not allowed.
Parameters: %1 = Channel number
Definitions: The computing time available to the NCK has been reduced, starts have therefore been locked. The
computer performance is inadequate for smooth program execution. The computing time of the NCK
may have been reduced by the HMI because of an HMI part program simulation.
Reaction: Alarm display.
Remedy: Wait for the simulation to end or press RESET in any channel.

Parameters: %1 = Channel number
%2 = Block number, label
Definitions: The maximum number of symbols defined by machine data 28020
$MC_MM_NUM_LUD_NAMES_TOTAL has been exceeded.
Reaction: Interpreter stop
NC Start disable in this channel.
Interface signals are set.
Alarm display.
Remedy: Please inform the authorized personnel/service department.
