Detailed description
2.12 Program runtime/workpiece counter
Activation
The workpiece counters are activated or the reset timing and counting algorithm are
specified via the following two channel-specific machine data:
MD27880 $MC_PART_COUNTER (activation of workpiece counters)
Bit Value Significance
0 1 $AC_REQUIRED_PARTS is active
1 0 Alarm/VDI output with: $AC_REQUIRED_PARTS == $AC_ACTUAL_PARTS
1 Alarm/VDI output with: $AC_REQUIRED_PARTS == $AC_SPECIAL_PARTS
4 1 $AC_TOTAL_PARTS is active
5 1 With M2 / M30: $AC_TOTAL_PARTS += 1
6 1 Equality under M function of $MC_PART_COUNTER_MCODE[ 0 ]: $AC_TOTAL_PARTS += 1
8 1 $AC_ACTUAL_PARTS is active
9 0 With M2 / M30: $AC_ACTUAL_PARTS += 1
1 Equality under M function of $MC_PART_COUNTER_MCODE[ 1 ]: $AC_ACTUAL_PARTS += 1
12 1 $AC_SPECIAL_PARTS is active
13 0 With M2 / M30: $AC_SPECIAL_PARTS += 1
1 Equality under M function of $MC_PART_COUNTER_MCODE[ 2 ]: $AC_SPECIAL_PARTS += 1
MD27882 $MC_PART_COUNTER_MCODE[ <Index> ] (workpiece counting via user-specific M function)
Index Significance
0 Value of M function with which $AC_TOTAL_PARTS is counted up.
1 Value of M function with which $AC_ACTUAL_PARTS is counted up.
2 Value of M function with which $AC_SPECIAL_PARTS is counted up.
Boundary conditions
• All workpiece counters are set to the default values on control power-up and can be read
• If $AC_REQUIRED_PARTS = 0, no ID check is performed with the counter pulse for
204
and written independent of their activation.
$AC_ACTUAL_PARTS or $AC_SPECIAL_PARTS even if the MD bit is set.
Basic logic functions: Mode group, channel, program operation, reset response (K1)
