Description Limit Comments
Maximum number of all CFC charts
considering all task levels
32 When the limit is exceeded, the device rejects the parameter
set displaying an error message, restores the last valid pa-
rameter set and uses it for restarting.
Maximum number of all CFC charts
considering one task level
16 When the limit is exceeded, an error message is output by
the device. Consequently, the device is put into monitoring
mode. The red ERROR-LED lights up.
Maximum number of all CFC inputs
considering all charts
400 When the limit is exceeded, an error message is output by
the device. Consequently, the device starts monitoring. The
red ERROR-LED lights up.
Maximum number of reset-resistant
flipflops
D_FF_MEMO
350 When the limit is exceeded, an error message is output by
the device. Consequently, the device starts monitoring. The
red ERROR-LED lights up.
