The dimension is configured via $MN_PLCIO_NUM_BYTES_IN.(MD10394) Start addr. of the directly readable input bytes of the PLC I/Os $MN_PLCIO_LOGIC_ADDRESS_IN (MD10395) The machine data MD10394 $MN_PLCIO_NUM_BYTES_IN and MD10395 $MN_PLCIO_LOGIC_ADDRESS_IN must be consistent with the PLC-side configuration Examble I100.0 $MN_PLCIO_NUM_BYTES_IN = 1 $MN_PLCIO_LOGIC_ADDRESS_IN 100 NC Program DEFBOOL I100_0 ; I100.0 I100_0 = ($A_PBB_in[0] B_AND 1)
