SINUMERIK 840Di sl Manual (HBIsl) - - 01/2007 Edition
Before performing the expanded message frame configuration, you need to
configure the DP slave 611U with the standard message frame required for this
drive.
For information on how to perform a standard configuration of the DP master,
please see Section 8.10, Page 8-231et sqq.
To transfer the additional process data, you need to change the configuration of
the DP slave 611U as follows:
1. The length of the PDA ,which is already configured with the standard mes-
sage frame, must be expanded by the length of the additional PDA.
2. As the I/O address of setpoint and the actual value of an axis must be the
same, change the I/O address of the setpoint to the I/O address of the ac-
tual value which is automatically adapted by the HW Config if necessary.
Dialog box: DP slave properties
Tab card: Configuration
Actual value > length: <Length standard PDA + length additional PDA>
Setpoint > I/O address: <I/O address actual value> (see above 2.)
OK
Notice
S The I/O address for setpoint and actual values of an axis must be the same.
I/O address actual value = = I/O address setpoint
The I/O address set by the SlaveOM for an axis must match the I/O
S
address set in the NC.
There is no automatic adjustment!
The following data must agree:
1. SIMATIC S7 configuration of DP slave 611U
I/O address
2. SINUMERIK 840Di sl NC
MD13060: DRIVE_LOGIC_ADDRESS[n] (logical drive address)
Note
After increasing the length of the actual value PDA (dialog box: DP slave
Properties > Configuration > Actual value > Length), when the Properties dialog
box is opened again, in message frame type:
Dialog box: DP slave properties
Tab card: Configuration
Default: <Frame type>
the message frame type that was originally selected is no longer displayed, but
the message frame that matches the modified PDA or no message frame type.
