Introduction of Features
PROFINET
PROFINET is an Ethernet-based industrial network communication protocol created by PI
(Profibus & Profinet International). By using Ethernet-based communication, you can meet
the requirements of high-speed input/output data communication and equipment parameter
monitoring and configuration.
Devices that support PROFINET are available from many vendors. Our GX, GP, and GM
support communications with PROFINET IO controllers, such as PLCs, by incorporating a
PROFINET communication function (PROFINET module).
Component devices
• IO controller
The IO controller is a controller such as a PLC with a control program. Data exchange is
performed to the specified IO device when configuring the system.
• IO device
An IO device is a device that the IO controller accesses to read and write data to.
The SMARTDAC+ is an IO device.
• Configuration tool
A tool to configure the system. The PC or software that the configuration software is
installed on.
• Switch
A network repeater.
• Cables
Use a PROFINET communication-compatible cable.

Cable connection
Connect the Ethernet port of the GX/GP/GM main unit and the Ethernet port of the
PROFINET module (either one of the two ports) with an Ethernet cable (STP cable, CAT 5 or
higher)1.
• Communication between the GX/GP/GM main unit and the PROFINET module is
performed using the Modbus protocol.
1: We recommend an Ethernet cable length of 1 m or less.
• You can connect to the Ethernet network from the other Ethernet port of the PROFINET
module.
There are limitations on the link detection operation of the GX/GP/GM main unit.See
“Restriction on link detection operation of the GX/GP/GM main unit when connecting to
an Ethernet network” on page 7.
Connect the PROFINET communication cable to the PROFINET port of the PROFINET
module to connect to the PROFINET network.
Do not use an Ethernet cable whose plug does not comply with FCC specifications.
Doing so can cause a malfunction.
SMARTDAC+ configuration
Reconfiguring the PROFINET module
Reconfiguration is performed to recognize the PROFINET module installed in the main unit.
For details on the reconfiguration, see below.
GX/GP: Section 1.29.4, “Reconfiguring the GX/GP” in the User's Manual (IM

IP address
The IP address of the PROFINET module’s Ethernet port (for Modbus clients).
• When the GX/GP/GM main unit setting is set to DHCP On, DHCP is also enabled for the
module, and the setting is disabled.
• Make sure that the IP address of the GX/GP/GM main unit does not overlap with the
default gateway and that it is the same subnet mask as the IP address of the GX/GP/GM
main unit.
Data interval
The interval at which the data is updated.
Maximum number of update cycles without data
Depending on the load of the GX/GP/GM main unit and the network status of the Ethernet,
data may not be updated. If data is not updated continuously for a set number of times,
the diagnostic information is sent to the IO controller. When the data is updated, the
transmission to the IO controller is stopped.
• While the diagnostic information is being transmitted, the module status LED blinks
green.
See “Troubleshooting” on page 26.

Modbus server function limitations
• Number of Modbus server connections: Max 2
Limitations when using communication channels
In PROFINET cyclic communication, the following communication channels are always
written from the PLC.
Model Communication channel
GX10/GP10 From C001 to C020
GX20/GP20/GM10 From C001 to C050
If you want to use the communication channel with other functions, check whether the above
channels are used. If the writing conflicts, change the setting to avoid conflicts.
• When using the wireless input unit GX70SM (for GX20/GP20/GM10)
Conflicting channels C001 to C050 correspond to wireless input unit numbers 1 to 10.
When using wireless input unit numbers 1 to 10, the unit number must be changed
(wireless input unit reconfiguration). For details on wireless input unit reconfiguration, see
below.
GX70SM Wireless Input Unit User’s Manual (IM 04L57B01-01EN)
Restriction on link detection operation of the GX/GP/GM main unit when
connecting to an Ethernet network
• The status of the link between the PROFINET module and the Ethernet network cannot
be checked on the general log screen of the GX/GP/GM main unit.
• The following messages are not displayed even if the Ethernet network link status
changes.
“821 Ethernet cable connected.”
“822 Ethernet cable disconnected.”
• When using DHCP, the IP address acquisition/release operation is not performed when
connecting to/disconnecting from the Ethernet network after powering on.
• When the IP address is not obtained, the GX/GP/GM main unit and the PROFINET
module do not obtain the IP address even when connected to an Ethernet network.
• When obtaining the IP address, the GX/GP/GM main unit and the PROFINET module
do not release the IP address even when disconnected from the Ethernet network.
If you need to obtain/release the IP address,See “Obtain/release the IP address of the
PROFINET module when using DHCP” on page 6.
• When using an email/FTP client, if the cable of the Ethernet network is disconnected, the
following error message is displayed.
“658 Could not connect to SMTP server.”
“692 FTP control connection error.”
