1.6.4 Basic System: Third-Party Devices and PME Programmer
Third-party IO Devices can be used with the RX3i PROFINET Controller if their manufacturer provides a GSDML
file that can be imported into Proficy Machine Edition (PME). The GSDML file defines the characteristics of the
IO-Device and its I/O modules. Importing a third-party IO-Device GSDML file and configuring third-party IO-
Devices are described in Chapter 3, and in the Proficy Machine Edition online help.
After receiving a third-party device’s configuration, the RX3i PROFINET Controller connects to the third-party
IO-Device if the device is available, transfers the configuration to the device, and starts exchanging I/O and
alarm data with the device.
Figure 8 shows a programmer connection (for configuration, user logic programming, and monitoring), the
concept of GSDML import, an optional external Ethernet switch, and the ability to connect field buses to a
PROFINET IO-Device. Third-party IO-Devices that have only one Ethernet port may require the use of an
external switch.
