18.2.3
Project design: SINAMICS S120 and SIEMENS message frame 116
When using SIEMENS message frame 116 no further measures are required other than
those applied for standard configuration.
18.2.4
Project design: SINAMICS S120 and expanded message frame configuration
Standard engineering
Before configuring the additional drive variables, please define the following:
●
The SIEMENS message frame that is to be used.
●
The additional drive variables/PDA that are to be transferred.
Note
When transferring additional drive variables to the specific system variables, we
recommend always using SIEMENS message frame 116.
Recommended configuration sequence
When configuring the components included in the frame, we recommend the following
sequence:
1.
DP master
2.
DP slave S120/Drive
3.
SINUMERIK 840Di sl NC
1. Configuring the DP Master: Standard engineering
When using the extended message frame configuration, you must first apply the standard
configuration to the DP master with respect to the DP slave S120 with the SIEMENS
message frame required for cyclic communication.
For information on how to perform a standard configuration of the DP master, please see
Section "DP slave SINAMICS S120" (Page 287).
Expanded message frame configuration
Perform the following actions to configure the additional PDA:
1.
Open the "DP slave properties" dialog for the drive unit by double-clicking the relevant DP
slave S120 in the HW Config station window.
2.
Expand the length of the PDA already configured with the SIEMENS message frame in
the actual value slot of the relevant drive by the length of the additional PDA.
3.
The setpoint and actual value of an axis must have the same I/O address. If HW Config
changes the I/O address of the actual value slot as a result of expanding the PDA, you
must modify the I/O address of the setpoint slot accordingly.
