INTRODUCTION
SD750 drives are compatible with several optional boards:
•Communication boards (Ethernet/IP, Profinet, CANopen…).
•Encoder board.
•Digital and analog I/O expansion boards.
•Optical fiber board
…among others. Up to three optional boards can be connected, maximum two of the same type.
This manual focuses on the optional communication board Profinet. The Profinet board allows the
SD750 to be configured as a slave of a PLC master using the Profinet industrial communication protocol.
This communication allows information to be exchanged between both devices through the configuration
of reading and writing variables.
Thanks to this board, the SD750 drive can be controlled and monitored through the network, either by the
user or through a PLC sequence program or any master device. Also, Profinet is easy to connect, allowing
a faster installation and easier maintenance.

CONNECTION TO THE DRIVE

EN
CONNECTION TO THE DRIVE
The Profinet board can be connected directly, through the connector on its back side, to any of the three
expansion connectors of the SD750 drive central control board. Once connected, it allows integrating the
SD750 drive in an Profibus network.
Once connected, it allows integrating the drive in a Profinet network. One Profinet board will be necessary
for each equipment which is going to be connected to such network.
CAUTION
Power Electronics’ SD750 drives operate with a high electric energy.
Make sure the power supply has been disconnected and wait for at least 10 minutes to guarantee that
DC bus is discharged before installing the Profinet board. Otherwise, there is a risk of personal injuries
or accidents.

Connectors description and LED indicators
The LED indicators on the Profinet expansion board provide information about the board and
communication status. Please notice that some LEDs are bicolor and will change their color and
frequency according to the situation. Refer to the following table for the description of all posible colors
and frequency of each LED indicator, as well as what they represent.
All leds are explained in the following table:
LED COLOR / FREQUENCY DESCRIPCIÓN
STATUS
Red, steady Hardware failure or inability to install the protocol.
The board probably has to be repaired.
Red, slow blinking The board cannot stablish communication with the network
controller or initialize the protocol.
Red, fast blinking The board cannot stablish communication with the SD750
central board.
Green, slow blinking The system is operating correctly 1.
Green, fast blinking Test mode. User has set the board to test mode.
RUN Green User application is running without errors.
READY Green Board’s operating system is working correctly.
ETH1
Green, steady Device operational: The devices is operating correctly
Green, flashing Standby: The device has not been configured.
Red / green, flashing Self-test: The device is performing its power up testing.
Red, flashing
Minor fault: the device has detected a recoverable minor fault.
E.g. an incorrect or inconsisten configuration can be considered
as a minor fault.
Red, steady Major fault: The device has detected a non-recoverable major
fault.
Off No power: The power supply to the device is missing.
1When we state that the system operates correctly, it means that the communication between the expansion board, the
network controller and the central SD750 microcontroller is correct. This does not mean, however, that the communication
with the PLC is correct.

Finally, the two RJ45 connectors ETH1 and ETH2 allow ring communication in the Profinet network (the
board can be connected to two different networks).

COMMISSIONING
COMMISSIONING
The Profinet expansion board allows configuring the SD750 drive as a Profinet industrial communication
slave. Once connected the board to the expansion connectors and loaded the GSDML in the PLC master,
the parameters of the drive related to Profinet communication must be configured.
The following steps must be followed:
1. Load GSDML file in the PLC master.
Once the GSDML file is loaded, which allows us to introduce the SD750 device into a Profinet
network, the configuration from the PLC master will indicate to the system how many variables are
going to share, both writing variables (from the PLC to the SD750) and reading variables (from the
SD750 to the PLC). In both cases, the number of variables that can be selected is in power of 2,
from 0 variables to 16. In other words, 0, 2, 4, 8, or 16 input variables can be configured and, in the
same way, 0, 2, 4, 8 or 16 output variables. These variables are called Custom Modbus (see section
“Object Custom Modbus”).
2. Configure network parameters (G21, see section “Parameters settings”) so they match with the
data expected by the master
3. Configure the Profinet slave on the PLC master (network configuration and number of shared
variables).
The Master Input variables are the first 16 Custom Modbus variables, while the Master Output
variables range from Custom Modbus 17 to 32.
4. Configure the Profinet slave on the PLC master (networkconfiguration and Custom Modbus related
to the shared variables). Network configuration is found in group G21.4.1. In case object Custom
Modbus is used, configure variables in groups G21.4.2 and G21.4.3.
5. Verify communication is stablished. Configure action in case of communication faults with the
master.
6. Connect communication wiring and ensure communication with the SD750 is correct (G23.3).
Configure action in case of communication fault.
Once the slave has been configured correctly, both in the PLC and in the SD750 itself, the connection may
be made, and the configured variables will be shared.
The rest of the commissioning depends on the PLC, the program used, etc.

Parameters setting
Up next, the relevant parameters are summarized. For details about the range of values and Modbus
addresses, refer to the Software and Programming Manual for SD750 drives.
Subgroup 21.4: Profinet
Subgroup 21.4 of the SD750 drive allows configuring Profinet.
•G21.4.1: Network parameters configuration group.
•G21.4.2: Configuration group of the master’s input variables for object Custom Modbus (PE
Status). The number of variables to configure will depend on the number of variables selected in
the master.
•G21.4.3: Configuration group of the master’s output variables for object Custom Modbus (PE
Status). The number of variables to configure will depend on the number of variables selected in
the master, up to 16.
•G21.4.4: Read-only parameter, shows whether connector 1 of the Profinet board is off or on.
•G21.4.5: Status of the connector 1 and response in case there is no communication with the
master.
o[Fault] If timeout is exceeded, the fault F110 will be triggered. F110: Lost c1 Profinet
comm.
o[Ignore]. Fault F110 will not be triggered.
•G21.4.6: Read-only parameter, shows whether connector 2 of the Profinet board is off or on.
•G21.4.7: Enables the fault associated to the Profinet connector 2 [Ignore, Fault].
o[Fault] If timeout is overcome, the fault F111 will be triggered. F111: Lost c2 Profinet
comm.
o[Ignore]. Fault F111 will not be triggered.
NOTICE
The status of connectors indicates the of communication status with the PLC master. In case the
application does not require ring connection, the SD750 will have to be configured to ignore the fault of
the unused connector.

Object Custom Modbus
This is a customized object, with a single instance. Each attribute represents a custom Modbus value
(1 ... 32). Attributes 1 to 16 are read-only for the master (Get) and from 17 to 32 are write-only (Set).
Note: For the correct operation of this object, user must configure the custom parameters in groups
G21.4.2 and G21.4.3 of the SD750. Attributes of the object Custom Modbus make use of these
parameters, so the user is capable of configuring them with the variables from the SD750 drive that
are most relevant to him.
