Parameters: %1 = Channel ID %2 = Action number/action name Definitions: Currently, the alarm occurs only in combinatio n 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, leav ing channel 2 executing until its natural end, stopping channel 2 in order to deselect program test again. Reaction: NC Start disable in this channel. Interface signals are set. Alarm display. NC Stop on alarm. Diagnostics Manual (DAsl), 03/2009 Remedy: Alarm can be switched off with MD10708 $MN_SERUPRO_MASK bit 1. Program Continuation: Clear alarm with the RESET key. Restart part program
