Main Features
The Option Board 3G3AX-MX2-PRT-E and the 3G3AX-RX-PRT-E allow con-
trolling, monitoring and parameterization of an Inverter via a PROFIBUS net-
work.
The Option Board serves as a gateway that passes communicated register
values from the PROFIBUS network to the Inverter and vice versa.
The following functions are available via PROFIBUS communication by install-
ing the Option Board:
Cyclic Data Exchange
The PROFIBUS Master and Option Board can exchange data via a PROFI-
BUS DP-V0 message connection:
• Output data (from PROFIBUS Master to Option Board):
E.g. Run/stop, Reference frequency and Fault reset
• Input data (from Option Board to PROFIBUS Master):
E.g. Inverter status, Output frequency and Output current
Inverter Parameter Access
The PROFIBUS Master can read and write parameter data via the
Option Board using the mailboxes provided by some modules, as well as a
PROFIdrive DP-V1 parameter channel.
Simplified Start-up
The Option Board can be set up easily, just by wiring the Unit, setting the
PROFIBUS node address (P180) and device profile (P182) and restarting the
unit. The Unit's configuration is read automatically when the power is turned
ON. It is not necessary to make any settings with a special Programming
Device.
Simplified Replacement
All parameters required by the Option Board are stored in the Inverter. The
Option Board can be replaced, requiring no re-configuration.
Automatic Baud Rate
Recognition
The Option Board automatically detects the Master's communication baud
rate, and no user configuration is required.
Note
The PROFIdrive DP-V1 parameter channel is only available if the PROFIBUS
Master also provides DP-V1 Class 2 (MSAC2) Messaging to the user.
Note
If the PROFIBUS Master's baud rate changes, the PROFIBUS Communica-
tion Unit must be turned OFF and then ON to detect the new baud rate.
