Bus/GENIbus/G120P data points can be made available to all the devices and
applications in the Desigo system.
The PXC50..D, PXC100..D and PXC200..D automation stations support TX
Open. You can attach up to five TX Open modules to one PXC automation
station.
Xworks Plus (XWP) is used to engineer all solutions. Various compounds are
available, e.g., for pumps, variable speed drives and heat meters.
Predefined solutions allow for simple commissioning. Solutions for Grundfos,
Wilo, Danfoss and G120P are delivered as part of the HQ CAS Library. For M-
bus and Modbus, sample solutions serving as device description templates are
provided (TX Open templates).
The following solutions on the TX Open platform are available:
● TX Modbus
● TX M-Bus
● TX G120P/SED2
● TX Grundfos via GENIbus
● TX Open platform (SDK)
TX Modbus supports Modbus RTU and Modbus TCP, Wilo pumps and variable
speed drives. TXI2.OPEN supports 160 data points. They may be distributed in
any fashion to the devices for the Modbus system. The number of devices is
only limited by the 160 data points.
See
TX Modbus Engineering Guide (CM110571).
TX M-Bus supports templates for meters. The regional companies can create
templates. You need a level converter for TX M-Bus. TXI2.OPEN supports 160
data points. They may be distributed in any fashion to the devices for the M-
bus system. The number of devices is only limited by the 160 data points.
See
TX M-Bus Engineering Guide (CM110572).
TX G120P supports the integration via the Modbus and USS protocol. You can
integrate up to eight G120P variable speed drives per TX Open module into the
Desigo system.
See
TX G120P Engineering Guide (CM110576).
TX SED2 supports the integration via the USS protocol. You can integrate up to
eight SED2 variable speed drives per TX Open module into the Desigo system.
You can add new G120P variable speed drives to an existing TX Open (USS)
with already installed SED2 drives, e.g., when:
● A defective SED2 needs to be replaced with a G120P in an existing project
● An existing project with installed SED2 drives needs to be extended with a
new G120P
See
TX SED2 Engineering Guide (CM110573).
TX Grundfos supports the integration of Grundfos via GENIbus. You can
integrate up to eight Grundfos pumps into the Desigo system.
See
TX Grundfos / GENIbus Engineering Guide (CM110574).
HQ provides the TX Open Platform Software Development Kit (SDK), including
training, for experts in the regional companies. The training course provides the
necessary tools and knowledge to create new protocol applications.
