1.1 Intended use
The gateway is the connection point between the Ho-
val CAN bus and a Modbus interface via TCP or RS485
(RTU).
The gateway enables users to access and operate their
Hoval heating system via Modbus.
These instructions describe how to connect, install and
commission the interface.
1.2 Explanation of the symbols

3.3 Connection for the heat generator (WEZ /
CAN bus)
There is a danger of electric shock.
The heat generator can only be de-energised
by disconnecting it from the mains (fuse).
NOTICE
The gateway can be connected to the CAN
bus at any point on the bus system.
•
In doing so, ensure that the CAN bus is
correctly terminated.
1. Plug the CAN bus into the gateway
or establish the CAN connection via the terminals on
the back of the gateway.

the gateway is currently in. The LEDs indicate the current
status for this purpose.
The LED electrical power supply is green, all other LEDs
are dark.

4. Commissioning the TopTronic®E
Gateway module Modbus
The settings described below can be perfor
-
med on the control module of the system.
4.1 Connecting the Modbus TCP/RS485 (RTU)
to the gateway
1. Launch the TopTronic®E control module and select
- Main menu > Service.
g. 12
Only required for Modbus TCP:
Service > TTE-GW > General > Gateway general > All
data points > Internet access
2. Select network (=cable connection) and conrm with
“OK”.
> Network is set as standard.
3. DHCP (router gives the address)
- DHCP > Yes is set as standard.
- Open and select DHCP > Yes > Apply IP changes >
Apply and conrm with “OK”.
- This automatically searches for and sets the correct
IP address. The TopTronic® E gateway is installed.
For Modbus TCP, DHCP should be set to “No”
and a static IP address should be given as the
IP address cannot be changed as a result.
Only required for Modbus TCP:
4. Set a xed IP address, this setting can be carried out
by a specialist.
- Set DHCP > No.
- Open > IP address, enter the required IP address
and conrm with “OK”.
- Open > Subnet mask, enter the required subnet
mask and conrm with “OK”.
- Open > Default gateway, enter the required IP
address and conrm with “OK”.
- Open and select > Apply IP changes > Apply and
conrm with “OK”.
- The TopTronic® E gateway is installed.
A reliable IP mask must be entered in the sub
-
net even if the system does not have a default
gateway.
5. When the connection has been established, the ga-
teway is restarted; the control module continues to
operate. The gateway must be restarted manually if it
does not restart automatically.
Service > TTE-GW > General > Settings > All data
points > Restart
The restart can take a few minutes.
6. The Modbus is congured via TTE-GW > Modbus >
Settings.
- Active: Activates or deactivates the Modbus service
- UnitID: Modbus address of the gateway for Modbus
RTU
- Mode: Modbus RTU (via RS485) or Modbus TCP
- Parity: Even, uneven or none. This setting must be
the same on all units in the RS485 bus system.
- Baud rate: This setting must be the same on all
units in the RS485 bus system.

5. General Modbus information
On the gateway, Modbus RTU is implemented via
RS485 and Modbus TCP via Ethernet. Either Modbus
RTU or Modbus TCP can be used. The two protocols
cannot be used at the same time.
The following Modbus function codes are implemented:
• Function 03 (03hex) Read Holding Registers
• Function 04 (04hex) Read Input Registers
• Function 06 (06hex) Write Single Register
However, no more than 10 to 15 data points should be
read at the same time as this can cause the time for ge-
nerating the response to increase signicantly.
Modbus uses the terms “register” and
“address”. Whilst the registers begin with the
number 1, the addresses start with 0. The data
point list uses Modbus addresses to address
the data points.

(Explanation further below)
DatapointName TypeName Decimal
Name of the data point
in the Hoval CAN bus
Indicates whether a data point is unsi-
gned (U) or signed (S).
The length in bit of the data point is
also given.
(e.g. U8, S16, S32)
The number of decimal places that
the value has.
(e.g. if the value 263 (decimal) is
transmitted and “Decimal” is 1, the
value is represented as 26.3.)
FunctionGroup name Function name Steps
Indicates the Hoval CAN bus data
point function group where the value
can be found (e.g. heating circuits)
Indicates the Hoval CAN bus data
point function where the value can be
found (e.g. heating circuits 1)
Indicates the number of valid steps
when adjusting values.
(e.g. 5 -> value may only take on 0,
5, 10, etc.)

If a selection is possible on control module, this column indicates
the value that represents the selection.
(e.g. text 0 is “Standby”, text 1 is “Week 1” -> Value 0 of the Modbus
data point represents “Standby”, value 1 represents “Week 1”)

6.2 Module addresses
The “UnitId” column indicates the Hoval CAN bus address
of the module that is to be addressed. If, for example, an
MWA is congured with number “1” via the control modu-
le, this corresponds to the “UnitId” “385” in the Modbus
data point list.

6.3 Special data points
6.3.1 Four-byte data points
If a data point of the Hoval CAN bus is longer than 2 by-
tes, the data point is distributed to 2 Modbus data points.
This is sufxed with “high” for high bytes and “low” for low
bytes.

6.3.2 Active errors
Active errors are complied of 9 Modbus addresses. The-
re is only an error if the “Active error X_error_type” data
point has a different value to 0xFF.
Active error 1_appearance_time Time of the appearance in minutes since midnight
Active error 1_appearance_date Date of the appearance in days since 1.1.1900
Active error 1_disappear_time Time of the disappearance in minutes since midnight
Active error 1_disappear_date Date of the disappearance in days since 1.1.1900
Active error 1_source Hoval CAN bus address of the module in which the error occurred.
Active error 1_function_group Hoval CAN bus data point function group where the error occurred
Active error 1_function_number Hoval CAN bus data point function where the error occurred
Active error 1_error_type Error type
Active error 1_error_code Error code
The meanings of “error type” and “error code” can be ta-
ken from the respective manuals of the modules.
6.3.3 LIST data types
If a text selection can be made for a data point on the
control module (e.g. “Standby”, “Week 1”, “Week 2”, etc.),
the LIST data type manages the text that is represented
by a number. Fields “Text 0” to “Text 31” of the data point
list indicate which number means what and which text it
represents. If, for example, the value of a LIST data point
is “2”, the setting, which is entered in the “Text 2” column
in the data point list, is active.
The value in the “Min. value” column regulates which
selection is permissible. This value represents a bit pat-
tern, which is laid over the 32 text columns and masks the
texts that can be selected.

Comment:
• Room set temperature for heating circuit: Set “Heating
operation choice” to constant and set required tempe-
rature below “Normal room temp. heating oper.”.
• Flow set temperature for heating circuit: “Heating ope-
ration choice” to manual. Set “Manual mode set tempe-
rature” to required temperature.
