1. INTRODUCTION
The following operating instructions merely serve as a supplement and
apply only in connection with the operating instructions of the Advanced
Energy power controllers Thyro-S and Thyro-A of types H1 and H RL1, as well
as Thyro-A H RLP1 as well as Thyro-AX of types H RL2 and H RLP2. Particular
attention must be paid to the safety instructions included in them.
1.1 GENERAL
The bus module Modbus RTU can connect up to 8 power controllers of
type Thyro-A...1, Thyro-AX...2 or power switches of type Thyro-S…1 to a Mod-
bus master in any random order.
Several bus modules can be employed at one device. Each bus module
occupies one address on the Modbus.
The power supply of the bus module is provided by an external 24 V
d.c. power source (150 mA), which is fed into X11.1 (+) and X11.2 (ground)
(reverse battery protected). The 24 V d.c. supply must be ungrounded when
operating under SELV. Several modules can be operated at one power supply.
For EMC reasons, the earth connection to X11.3 must be as short as possible.
The Modbus connector with a 9-terminal standard allocation must be con-
nected to the socket X20.
1.2 SPECIFIC CHARACTERISTICS
• The bus module is a slave component
• Function control via LED
• 8 free digital outputs X1.5 to X8.5
• processing of actual values as oat number in physical units
• C-rail assembly
• When the bus module is linked to Thyro-AX, please be aware that data trans-
fer is the same as for Thyro-A whereas special features or other additional
parameters are excluded from this.

3. FUNCTIONS
3.1 SETPOINT PROCESSING Thyro-S
The setpoints via the bus (setpoints master) are interpreted as an operating
mode with Thyro-S as shown in table 1.
SETPOINT RETURN VALUE
(setpoint master) (total setpoint)
to 409 = OFF 0
to 1091 = 1/5 819
to 1706 = 1/3 1365
to 3071 = 1/2 2047
to 4096 = ON 4096
TAB. 1 INTERPRETATION OF THE MASTER SETPOINTS WITH Thyro-S
The setpoint processing continues to depend on how the bus module is
connected to the power controller. For Thyro-S dierent variations can
be realised as required. The connection of terminal X22.4 of Thyro-S
controls the procedures (Chapt. 8, Fig. 4).
• No connection to X22.4
The bus module is fully functional, only the analog signal of control terminal
X22.1, however, is used as a setpoint (ON / OFF).
• X22.4 has ground potential
Only the master setpoints are used by the bus module (graded as in table 1).
The controller’s terminal X22.4 can be directly connected to earth if an alter-
native operation is excluded.
• X22.4 is switched
• Thyro-S’s terminal X22.4 is connected to one of the terminals X1.1 to X8.1
of the bus module (Fig. 4).
With malfunctions on the bus line an automatic switchover takes place to
the corresponding signal of the setpoint input of Thyro-S.
• Thyro-S’s connection X22.4 is connected to one of the terminals X1.5 to
X8.5 of the bus module (Fig. 4). The controllers can then individually be
switched (selectively) via bus to„Hand”.
With malfunctions on the bus line the last setpoint is automatically retai-
ned.

12
• Digital outputs with free drives
If a terminal X1.5 to X8.5 of the bus module is not allocated, a relay with 24 V
d.c. coil can be connected for free use (Fig. 1). The free circuit is integrated.
The driver current is maximum 120mA per output.
Ventilation cabinets, auxiliary heating, circuit breakers or control lamps for
example, can be activated with this via the Modbus.
3.2 SETPOINT PROCESSING Thyro-A/Thyro-AX
The setpoint processing depends on how the bus module is connected to the
power controller. For Thyro-A/Thyro-AX dierent variations can be realised
depending on the requirements. The connection of terminal X22.1 of Thyro-
A/Thyro-AX controls the procedures (Chapt. 7, Fig. 3).
• No connection to X22.1
The bus module is fully functional, however, only the analog signal of con-
trol terminal X2.4 is used as the setpoint.
• X22.1 has ground potential
Only the master setpoint is accepted by the bus module as a setpoint. The
controller’s terminal X22.1 can be directly connected to earth if an alternati-
ve operation is excluded.
• X22.1 is switched
• The terminal X22.1 of Thyro-A/Thyro-AX is connected to one of the termi-
nals X1.1 to X8.1 of the bus module (Fig. 3).
With malfunctions on the bus line all controllers are automatically swit-
ched over to the respective analog signal of the setpoint input of Thyro-A/
Thyro-AX.
• The circuit X22.1 of Thyro-A/Thyro-AX is connected to one of the terminals
X1.5 to X8.5 of the bus module (Fig.3). Then each controller can be switched
individually (selectively) via bus to„Hand”.
With malfunctions on the bus line the last setpoint is automatically retai-
ned.
• Digital outputs with free drives
If a terminal X1.5 to X8.5 of the bus module is not allocated, a relay with 24
V d.c. coil can be connected for free use (Fig. 1). The free circuit is integrated.
The driver current is maximum 120 mA per output.
Ventilation cabinets, auxiliary heating, circuit breakers or control lamps, for
example, can be switched via the Modbus.

3.4 ADDITIONAL FUNCTIONS FOR Thyro-S, Thyro-A AND
Thyro-AX
By using a bus module, additional functions for the power controllers
Thyro-S, Thyro-A and Thyro-AX can be employed.
All the accessible parameters of both type ranges can be found in
columns S/A (abbreviation for Thyro-S and Thyro-A; these modications also
apply for Thyro-AX) under R/W in table 8.
The most important parameters are described in more detail in the
according power controller operating instructions. Here r = read,
i.e. can only be read, r/w = read and write possible.

14
4. OPERATION
The Modbus connection is lead through
a 9-pole sub-D bushing (X20). It provides
the data lines A and B as well as an electrically
isolated supply voltage (5 V, 80 mA).
4.1 SELECTING THE BUS ADDRESS
A device address, which only exists once in the system, must be set in a
switched-o state between 1 to 247 at the bus module via the switch
S501.1 to S501.7.
4.2 SETTING THE TRANSMISSION PARAMETERS
The settings which are required for communication assimilation can be
made via the DIP switch S502 (conguration switch). At the standard
setting all switches are open. The following table illustrates the function
of the switches. 0 represents an open switch and 1 a closed switch.
1 = CLOSED
0 = OPEN

Baud rate: Works setting = 4800 Baud.
The baud rate can be set with the rst three switches. The transmission
rates of 4800 to 230 400 baud are sustained.
Parity: Works setting = no parity
This switch activates transmission with parity bit.
Even nOdd: Works setting = Odd
With activated parity bit it is possible to switch between Even and Odd
parity.
2 Stopp-Bit: Works setting = 1 Stopp Bit
This switch allows an additional Stopp Bit to be sent.
Long Break: Works setting = no extension
This switch allows the delay time between master inquiry and slave reply to
be increased by 3.5 bytes.
4.3 MODBUS/J BUS LOG
The transmission mode RTU (Remote Terminal Unit) is used for communica-
tion.
