Assignment of the process data from the controller:
13.3.2.2 Monitor data words from the controller (tx_par1 and tx_par2)
The monitor data words "tx_par1" and "tx_par2" can be assigned via control bits in
control word Ctrl1 with different display values:
ƒ Control bit 0 ("Ctrl1-Func1")
ƒ Control bit 1 ("Ctrl1-Func2")
ƒ Control bit 2 ("Ctrl1-Func4")
The following assignment of the monitor data words can be set via the control bits:
Word 1 Word 2 DWord (word 3 + word 4)
LOW byte HIGH byte LOW byte HIGH byte LOW word HIGH word
Byte 1 Byte 2 Byte 3 Byte 4 Byte 5 Byte 6 Byte 7 Byte 8
Status word Stat1 Status word Stat2 tx_par1 tx_par2
Control bits 0..2
