It is assumed that the users of the manual will have all the knowledge and skills needed to carry out the required tasks. 1.2 Contents Important The manual starts with a description of the display and control panel of the PXM20 (BACnet/LonTalk) and PXM20-E (BACnet/Ethernet/IP) operator unit and presents the procedures for navigation and for editing values, which are always the same. The second part of the manual leads you step by step through the various activities involved in commissioning and maintaining the plant. As there may be significant differences between one plant and another, and between the read and write access of one user and another, it follows that it is not possible to provide a description which is generally applicable to every individual case. "Favorite" objects, for example, are special objects containing important values, which can be accessed with a short-cut operation. The question of exactly which objects and which values these are, is determined in the engineering phase according to the individual needs of the plant operator. For this reason, the descriptions in this manual are intended as examples, designed to clarify the basic operating principles of the PXM20 operator unit. 6/72 Siemens Building Technologies PXM20 / PXM20-E operator unit 3BAbout this manual CM110754en_06 2017-04-05 Note!

In third-party devices, the following BACnet objects can be displayed: · Analog Input/Output/Value objects · Binary Input/Output/Value objects · Multistate input/Output/Value objects · Calendar object · Device object Only a subset of the standard properties, as in the BACnet standard, is displayed. In the context of PXM20 and PXM20-E, the term "third-party" or "devices from third-party manufacturers" is used to refer to "non-PX devices". Siemens Building Technologies PXM20 / PXM20-E operator unit 5BSettings 25/72 CM110754en_06 2017-04-05 3.2.16 Domain ID (PXM20 only) Set the Domain ID for the PXM20 here. Important Figure 3-10 Domain ID This setting should be modified only by fully trained staff. 3.2.17 Network scope Use this option to specify whether the BACnet communication is to be local or global, i.e. whether PXM20 should be able to communicate only with BACnet devices connected to the same network, or also with BACnet devices connected to another BACnet network. BACnet networks are divided by BACnet routers. Communication within a BACnet network is local, while communication across all BACnet networks (connected by BACnet routers) is global. The setting Local/Global is has only effect with the PXM20 and with Siemens BACnet routers PXG... . With PXM20-E and with standard routers this setting has no effect, the communication is always global. As the PXM20(-E) registers itself as a temporary alarm recipient, the number of devices in a BACnet internetwork is limited. See CM110664en18, sections 18.3 and 18.4. This limit also applies when the BACnet internetwork has several UDP/IP segments, which are connected via IP/Ethernet routers. As soon as the number of PXM20(-E) is exceeded, no more devices are registered, or they do not find a site. This limitation can be avoided by using BACnet routers (PXG80-N, PXG3.L) and PXM20 with network scope "Local". This way the PXM20 is a temporary alarm recipient for the automation stations of the own LonTalk segment only. 26/72 Siemens Building Technologies PXM20 / PXM20-E operator unit 5BSettings CM110754en_06 2017-04-05 Important This setting should be modified only by fully trained staff. Notes · This setting is not visible to all users. · Local communication is only supported by the PXM20 and only with Siemens PXG... routers. With other models, and with PXM20-E, communication is always global.

No support of UIs and I/Os on TX-I/O modules. · Therefore the preferred method for wiring test is the Point Test Tool. Prerequisite Procedure The automation station which is the subject of the test must not be integrated into a site and must not be loaded with application software. Before the wiring test, a master reset of the automation station is recommended. A No site exists yet, i.e. no program has yet been loaded by an automation control station. Select WIRING TEST B A site already exists and you want to extend the network by one automation station: Log into the required site. Go to Alarming & functions and choose Wiring test.

Module No. Signal: AI = Analog input AO = Analog output BI = Binary input etc. Figure 11-4 Analog signals list From here you can select the various inputs and outputs and display further information. Note on analog inputs With the PX automation stations, the analog inputs in the application can be configured. During the wiring test (=No application loaded) it is always assumed that the analog input signal is a type LG Ni100 signal. Note on exiting from the wiring test Navigate to the top level (the openinig menu of the wiring test) by repeatedly pressing ESC, otherwise you will have to perform a master reset of the PX automation station before you can carry out a new wiring test. Notes on PXM20-E The PXM20-E operator unit must be able to communicate with the automation station via IP, and must not be configured for DHCP. The Foreign Device option must be disabled (this is also the default value). It is recommended that you operate the automation station to be tested and the PXM20-E operator unit in the same range as the default IP addresses and subnet masks. During the wiring test, the PXM20-E operator unit assigns the automation station a temporary IP address which is one digit higher than its own IP address: Example: IP address of PXM20-E: 172.16.87.14 IP address of automation station: 172.16.87.15. The use of this IP address is not checked. If the wiring test is carried out on a different PXM20-E operator unit, a master reset of the automation is required before you start.

Note Although it exists in the PXM20, this command is not needed within the Desigo system. The identification process is carried out with the Wink command. Figure 11-5 The "Wink" command To send the Wink command, select Send service pin message. This immediately triggers the Wink signal.
