官方故障排除步骤
Parameters: %1 = Channel number %2 = Block number, label Definitions: In the definition of a procedure (a subroutine) or in an EXTERN instruction, more than 127 formal parameters have been specified. Example: PROC ABC (FORMPARA1, FORMPARA2,...... FORMPARA127, FORMPARA128,...) EXTERN ABC (FORMPARA1, FORMPARA2,...... FORMPARA127, FORMPARA128,...) Reaction: Correction block is reorganized. Interface signals are set. Alarm display. Remedy: Press the NC Stop key and select the function "C orrection block" with the softkey PROGRAM CORRECT. The correction pointer positions on the inco rrect block. A check must be made to determine whether all parameters really have to be transferre d. If so, the formal parameters can be reduced by using global variables or R parameters, or by grouping together parameters of the same type to form an array and transfer them in this form. Program Continuation: Clear alarm with NC ST ART or RESET key and continue the program.
