Sinumerik Alarm 16942 Channel %1 start program command action %2 <ALNX> not possible
%1 = Channel ID
%2 = Action number/action name
Currently, the alarm occurs only in combination with the SERUPRO action. SERUPRO stands for search via program test. SERUPRO is currently searching the search target and has therefore switched this channel to the program test mode. With the START program command in channel 1, another channel 2 would actually be started, which means that axes would really be started during the search action. If this alarm is switched off (see help), the user can make use of the above behavior by initially selecting via PLC the program test mode in channel 2, leaving channel 2 executing until its natural end, stopping channel 2 in order to deselect program test again.
