User data
The received 8 bytes of user data are assigned to several variables of different data types. Data can
therefore be evaluated as —
·
binary information (1 bit)
·
control word/quasi−analog value (16 bits)
·
angle information (32 bits)
in the PLC program.

Tip!
Drive PLC:
·
All variables assigned to byte 1/2 can be freely used in the PLC program.
9300 Servo PLC:
·
In addition to signals such as IMP and CINH, the SB status word DCTRL contains some freely
assignable signals which can be overwritten via the variables DCTRL_bStateB..._b of the
SB DCTRL. More detailed information about the SB DCTRL can be found in the
"9300 Servo PLC" Online Manual.
·
The control signals for the quick stop (QSP), DISABLE, CINH, TRIP−SET and TRIP−RESET
function can also be read and processed via the following variables:
– AIF1_bCtrlQuickstop_b
– AIF1_bCtrlDisable_b
– AIF1_bCtrlInhibit_b
– AIF1_bCtrlTripSet_b
– AIF1_bCtrlTripReset_b
·
The remaining 11 bits (AIF1_bCtrlB..._b) can be used to control additional functions/function
blocks.
