The shield of the SERIAL cable must be connected to the earth at each end in order to ensure its
resistance to electromagnetic disturbances. Pin 4 of the connector may be used. However, it is
better to use a shield connection jumper, fixed at each end of the serial cable on a grounding rod or
a bottom plate of a cabinet.

2.2 Front panel indicators
1ON: is lit when the gateway is live.
2Net1 : is lit and steady if communication has not been established on PROFINET (Bus Failure). Flashes if
there is a communication error (Diagnostic).
3Net2 : is lit and steady if communication has not been established on the serial link. Flashes if there is a
communication error (Timeout).
4RUN: flashes at 1 Hz if the program has been executed correctly. Flashes at 4Hz if the “DCP blink” command
(PROFINET command for requesting the flashing) is currently being processed.
5Tx: indicates that a frame is currently being transmitted on the serial link.
6Rx: indicates that a frame is currently being received on the serial link.
2.3 DIP switches
DIP switches enable:
•activating a default IP configuration (192.168.10.20)
•selecting the physical support of the serial link: RS-232 or RS-485
•activating a termination resistance and line polarisation
Figure 3: DIP switches
2.3.1 Default configuration
A switch enables resetting to a default configuration (@IP 192.168.10.20, mask 255.255.255.0) when the
VPGATE Ethernet is switched on. The configuration takes place as follows:

A PROFINET IO controller might replace the IP address when VPGate is switched on if its station
name corresponds to the PLC program, even if the default IP configuration switch is activated.
2.3.2 Selecting the RS-232/RS-485 modes
A switch enables specifying the operating mode of the serial link in RS-232 or RS-485 (when delivered, VPGATE
is preset to RS-485):
RS-232 mode:
Figure 4: Serial network in RS-232 mode
This mode can only be used in case of communication between 2 individual devices (point-to-point
connection). The maximum distance in RS-232 is 15 m at 19200 baud.
RS-485 mode:
Figure 5: Serial network in RS-485 mode
This mode is used more often as it allows connection of several slaves on the bus. It also has other advantages
such as immunity to EMC disturbances and a greater inter-device distance than in RS-232. The maximum
distance in RS-485 is 1000 m.

2.3.3 Termination resistance
If the communication mode used is RS-485, there must be a termination resistance of 150Ω at both ends of the
network. A termination resistance is connected using DIP switches 3 and 4 (when delivered (VPGate is preset
without a termination resistance):
To ensure proper functioning of the termination, switches 3 and 4 must be in the same position.

3. SOFTWARE CONFIGURATION
3.1 Configuration tools of the PROFINET IO controller
VPGate PROFINET –SERIAL can be configured via the PROFINET network configuration software and is sent by
the PROFINET IO controller when the network is initialised.
The following detailed configuration was carried out using the "HW Config" configuration software of SIEMENS.
Nevertheless, the procedure is the same for all configuration software.
3.2 Integrating VPGate into a project
Before proceeding further, a project must be created in the engineering tool with a hardware configuration that
contains at least one PROFINET network and one IO controller.
3.2.1 Importing a GSDML file into the engineering tool
The GSD file allows using VPGate as a PROFINET IO device. It is called GSDML-V2-3-VPGate-20160412.xml and
can be found in the VPGate CD provided with the device.
The GSD file can also be accessed via the web server of VPGate (refer to paragraph 10).
This GSD must be imported via the PROFINET network configurator for VPGate to appear in the catalogue of
devices that can be inserted in the network.
Figure 7: Importing the GSD into the device catalogue
3.2.2 Integrating VPGate
The steps are as follows:
•Integrate VPGate into the network from the PROFINET device catalogue. The head module to be integrated
depends on the desired operating mode:
•MODBUS MASTER mode
•MODBUS SLAVE mode
•TRANSPARENT mode

VPGate PROFINET to serial user manual | June 2017 | ©PROCENTEC 15/104
Figure 8: Integrating VPGate into the network
•Configure the desired PROFINET name (this value is configured via the DCP in VPGate). This name allows the
IO controller to identify the device when the network is switched on.
Figure 9: List of devices that can be accessed via DCP
Figure 10: Naming a device via DCP
In the device properties in the network configuration tool, define the same PROFINET name that was previously
configured in VPGate:

Figure 11:Configuring the device name in the configuration tool
The cycle time for each device in the PROFINET network is determined at the level of the IO
controller. The possible cycle times are 2, 4, 8, 16, 32, 64, 128, 256 and 512 ms.
3.3 General configuration of VPGate
3 head modules are available, each corresponding to a communication mode on the serial link:
Gateway configuration in the TRANSPARENT mode
Gateway configuration in the MODBUS Master mode
Gateway configuration in the MODBUS Slave mode
3.3.1 General parameters
The parameters described below are common for all 3 head modules.
Once VPGate is inserted in the PROFINET network, the serial link must be configured using the following
parameters:

Defining the diagnostic management:
Figure 23: MODBUS MASTER mode diagnostic
(1): In the “Disabled” mode, the Digital output may be controlled by the “Digital Output” module if it is plugged
in.
(2): In these modes, the relay will be closed if there is a fault in the selected network:
•“On PROFINET SF” when communication with the PROFINET controller is lost.
•“On serial Link” when there is a communication error on the serial link.
•“On PROFINET and serial link SF” in case of both.
3.4 Configuration in TRANSPARENT mode
In this mode, data exchange is full duplex, without the master/slave concept. It is required to define the size of
frame received/sent by using the modules provided with the transparent mode.
The frames detected on the serial link are immediately copied in the “inputs bytes” modules plugged in
VPGate.
Similarly, if the format of a serial frame is detected in the PROFINET outputs, this frame is immediately sent on
the serial link.
For this, it is required to define the trigger for reading/sending frames in the head module “TRANSPARENT
MODE”.

For VPGate to function in the transparent mode:
•Insert the “TRANSPARENT mode” head module:
Figure 14: Inserting the “TRANSPARENT Mode” head module
•Then adapt the different parameters of the transparent mode:

(1): If this parameter is set to User defined, the end of frame character taken into account is the one specified
by the “User defined EOF” parameter. If it is set to “on timeout”, the reception timeout taken into account is
the one defined in the configuration of the serial link.
(2): If the parameter “EOF delimiter” is set to “on timeout”, only the frames received on the serial link will be
detected on timeout. On the PROFINET side, the 1st byte must is used to specify the length of the sent/received
frame (refer to paragraph 3.4.1). This byte is not transferred on the serial link.
(3): If the parameter “EOF delimiter” is set to “length in 1st byte” or to “on timeout”, the padding value is 0x00.
(4): This counter is used as a trigger:
•If this parameter is activated, the 1st byte of the PROFINET outputs must be a counter which is incremented
each time data is available and is to be sent. The usable data starts from the 2nd byte. If there is no counter,
the frame is re-copied from the 1st byte as soon as a change in the PROFINET outputs is detected.
