1. FUNKTION
Der Modbus Gateway ist eine Q-Network-Verbindungskomponente, die System-
status-Informationen ermitteln kann. Er macht eine Vielzahl an Informationen
zugänglich, die laufend vom XRGI®-System aktualisiert werden. Der Modbus
Gateway erlaubt es außerdem, das XRGI®-System fernzuüberwachen; dies kann
z.B. genutzt werden, wenn die VHP-Ready-Funktionalität gewünscht ist.
Der Modbus Gateway hat zwei Hauptfunktionen:
A U S L E S E N V O N I N F O R M AT I O N E N :
Nach dem Anschluss an das Netzwerk stehen die Informationen sofort (ohne
weitere Einrichtung) zur Verfügung.
EXTERNE ANSTEUERUNG XRGI®-ANLAGE:
Nach Initialisierung in der XRGI®-Steuerungssoftware kann der XRGI®-Betrieb
durch eine externe Ansteuerung beeinflusst werden. Ist die externe Ansteuerung
initialisiert, wird in der aktuellen Software-Version die XRGI®-Anlage ohne externe
Ansteuerung im wärmegeführten Modus betrieben.
Details zu den Hauptfunktionen sind in der Schnittstellenbeschreibung enthal-
ten (siehe Appendix).
V O R A U S S E T Z U N G E N Z U M E I N S AT Z
■ Der Modbus Gateway ist nur einsetzbar, wenn eine Displayplatine mit inte-
griertem Modem im iQ-Schaltschrank vorhanden ist (bei der alten Display-
platine ist das Modem separat). XRGI®-Anlagen mit älteren Displayplatinen
können umgerüstet werden. EC POWER stellt hierzu ein Umrüst-Kit zur Ver-
fügung.
■ Die Steuerung muss die Software-Version 1.11.5 oder höher haben. Ist in einer
XRGI®-Anlage eine niedrigere Softwareversion gegeben, ist ein Software-Up-
date erforderlich.

1. FUNCTION
The Modbus Gateway is a Q-network connected device that can be added to
provide the customer with system status information. A wide variety of infor-
mation is available, and is continuously updated by the XRGI® system.
The Modbus Gateway also provides a way to remote control the XRGI® system,
which can be used e.g. by customers who want VHP ready functionality.
The Modbus Gateway has two main functions:
R E A D I N G I N F O R M AT I O N :
Information is readily available (without the need for further equipment) once
connected to the network.
EXTERNAL CONTROL OF THE XRGI® SYSTEM:
Once the XRGI® control software has been initialised, the operation of the XRGI®
can be influenced by an external control. Once the external control has been in-
itialised, the XRGI® system is operated in heat-controlled mode without external
control in the current software version.
The description of the interfaces includes details on the main functions.
REQUIREMENTS FOR USE
■ The Modbus Gateway can only be used if the Central Control PCB with inte-
grated modem is fitted in the iQ-Control Panel (the modem is separate with
the old Central Control PCB). XRGI® systems with older Central Control PCBs
can be upgraded. EC POWER provides an upgrade kit.
■ Software version 1.11.5 or higher is needed. A software update is required if an
older software version is fitted in a XRGI® system.

A. APPENDIX
A.1 INTRODUCTION
The Modbus Gateway implements Modbus RTU on a RS485 bus.
On locations with more XRGI® systems, the Modbus Gateways connected to each XRGI® system can share the Modbus network.
A.2 RS485
The Modbus Gateway uses a galvanic isolated RS485 bus as the electric interface.
When the lid is removed, the information on the inside of the lid shows how to
connect the interface.
Terminator is active by default and is the setting used when the Modbus Gate-
way is also the bus end.
When multiple Modbus Gateways are used, only the Modbus Gateway at the bus
ends must have the terminator active. On all others, the jumper is removed to
make the terminator inactive.

The following function codes are the ones supported by the Modbus Gateway.
A.3.1 F U N C T I O N 01H ( R E A D C O I L R E G I S T E R S )
This function is used to read a contiguous block of coils. The request frame specifies the starting register address and the number
of coils to be read.
The coils in the response message are packed as one coil per bit of the data field. Status is indicated as 1 = ON and 0 = OFF. The
LSB of the first data byte contains the first coil addressed in the query, the other coils following toward the high end of the byte,
and from low order to high order in the subsequent bytes.

When the Control panel is set up to VHP, it is possible to control the behaviour of the system with
the parameters VPP mode and CHP Load Level.
Mode 0: Heat controlled mode, production at CHP load level from storage empty until storage
full, and standby until storage empty.
Mode 1: CHP runs maximal. Starts when T2 gets cold and stops when T3 gets hot.
VPP MODE Mode 2: CHP runs minimum. Starts when T1 get cold and stops when T1 gets hot.
Mode 3: CHP stopped.
Mode 4: CHP stopped, Electric heater runs minimum, starts when T1 gets cold and starts when
T1 gets hot.
Mode 5: CHP stopped, Electric heater runs maximal, starts when second last storage sensor gets
cold and stops when last storage sensor gets hot.
