7.1.5 Transferring status and control information of the device control
Via the user data bytes 1 and 2, you can exchange status and control information of the device
control (DCTRL) between different 9300 Servo PLCs via the system bus (CAN) in a simple manner.
Sending the status word of the DCTRL SB
Connect the variable DCTRL_wStat of the DCTRL SB to the variable CAN1_wDctrlStat to transfer
the status word of the DCTRL SB via the user data bytes 1 and 2.
Tip!
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 DCTRL SB.
Detailed information on the DCTRL SB can be found in the "9300 Servo PLC" Online Manual.
Transferring the control word to the DCTRL SB
Connect the variable CAN1_wDctrlCtrl to the variable DCTRL_wCAN1Ctrl of the DCTRL SB to
transfer the control word received via the user data bytes 1 and 2 to the DCTRL SB.
Tip!
The control signals for the functions quick stop (QSP), DISABLE, CINH, TRIP−SET, and TRIP−RESET
can be additionally read out and processed via the following variables:
·
CAN1_bCtrlQuickstop_b
·
CAN1_bCtrlDisable_b
·
CAN1_bCtrlInhibit_b
·
CAN1_bCtrlTripSet_b
·
CAN1_bCtrlTripReset_b
The remaining 11 bits (CAN1_bCtrlB..._b) can be used for controlling further functions/function
blocks.
