- Correction block is reorganized.
- Interpreter stop
- Interface signals are set.
- Alarm display.
Modify the NC program
Clear alarm with NC START or RESET key and continue the program.
Channel %1 block %2 invalid skip level with differential block skip
%1 = Channel number
%2 = Block number, label
With "Differential block skip", a skip level greater than 7 has been specified. (In packet 1
specification of a value for the skip level is rejected by the converter as a syntax error, i.e.
the only possibility is a "Suppress block" ON/OFF on one level).
- Correction block is reorganized.
- Interface signals are set.
- Alarm display.
Enter a skip level (number behind the slash) less than 8.
Clear alarm with NC START or RESET key and continue the program.
Channel %1 block %2 memory for variables not sufficient for subroutine call
%1 = Channel number
%2 = Block number, label
A called subroutine cannot be processed (opened), either because the internal data mem-
ory to be created for general purposes is not large enough, or because the available
memory for the local program variables is too small. The alarm can only occur in MDA
mode.
- Interpreter stop
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
Analyze the part program section:
1. Has the most useful data type always been selected in the variable definitions? (For
example REAL for data bits is poor; BOOL would be better)
2. Can local variables be replaced by global variables?
Clear alarm with the RESET key. Restart part program.
Channel %1 block %2 jump destination %3 not found
%1 = Channel number
%2 = Block number, label
%3 = Jump destination
In conditional and unconditional jumps, the jump destination within the program must be a
block with a label (symbolic name instead of block number). If no jump destination has
been found with the given label when searching in the programmed direction, an alarm is
output.
- Correction block is reorganized.
- Interface signals are set.
- Alarm display.
