I
Before commencing the installation
• Disconnect the power supply of the device.
• Ensure that devices cannot be accidentally
restarted.
• Verify isolation from the supply.
• Earth and short circuit.
• Cover or enclose neighbouring units that
are live.
• Follow the engineering instructions (AWA)
of the device concerned.
• Only suitably qualified personnel in
accordance with EN 50110-1/-2
(VDE 0105 Part 100) may work on this
device/system.
• Before installation and before touching
the device ensure that you are free of
electrostatic charge.
• The functional earth (FE) must be
connected to the protective earth (PE) or
to the potential equalisation. The system
installer is responsible for implementing
this connection.
• Connecting cables and signal lines should
be installed so that inductive or capacitive
interference do not impair the automation
functions.
• Install automation devices and related
operating elements in such a way that they
are well protected against unintentional
operation.
• Suitable safety hardware and software
measures should be implemented for the
I/O interface so that a line or wire breakage
on the signal side does not result in
undefined states in the automation
devices.
• Ensure a reliable electrical isolation of the
low voltage for the 24 volt supply. Only
use power supply units complying with
IEC 60364-4-41 (VDE 0100 Part 410) or
HD 384.4.41 S2.
• Deviations of the mains voltage from the
rated value must not exceed the tolerance
limits given in the specifications, otherwise
this may cause malfunction and dangerous
operation.
• Emergency stop devices complying with
IEC/EN 60204-1 must be effective in all
operating modes of the automation
devices. Unlatching the emergency-stop
devices must not cause restart.
• Devices that are designed for mounting in
housings or control cabinets must only be
operated and controlled after they have
been installed with the housing closed.
Desktop or portable units must only be
operated and controlled in enclosed
housings.
Moeller GmbH Safety instructions
Warning!
Dangerous electrical voltage!

II
• Measures should be taken to ensure the
proper restart of programs interrupted
after a voltage dip or failure. This should
not cause dangerous operating states even
for a short time. If necessary, emergency-
stop devices should be implemented.
• Wherever faults in the automation system
may cause damage to persons or property,
external measures must be implemented to
ensure a safe operating state in the event
of a fault or malfunction (for example, by
means of separate limit switches,
mechanical interlocks etc.).

1 General
Application field The S40-AM-TD application module, version 2.0, provides a
range of different function blocks. These function blocks
form the interface between telecontrol modules and the user
program in the PLC. They support the configuration of
telecontrol stations that are interconnected via a dial-up line
system. A telecontrol station consists of:
•PLC
• ZB4-501-TC1/-TC2 telecontrol module; only ZB4-501-TC1
telecontrol modules version 03 or higher can be used. It
must also be remembered that this module can only be
connected to PS4 controllers and that the address is
permanently set to 2.
• Dial-up modem; The use of a wireless modem on the
PS416-TCS-200 controller is not supported by the
hardware and software.
All telecontrol stations have the same rights. This means that
each station can establish a connection with another station
via a dial-up modem. Normally data is collected from several
remote stations in a central station and processed.
Depending on how the parameters are set, the stations can
have the same performance capabilities and provide all
services available. Alternatively, a station’s parameters can
be set so that only basic services can be carried out.

2 Data Arrays of the Function Blocks
Data exchange principle Data is exchanged between stations via “byte” type data
arrays. This means that data formatted differently in the
application must be converted prior to entry in the data
array. Conversely, array elements must be converted to the
data format of the application before they can be read.
The following example illustrates data exchange between
a station and two remote partner stations.
The “TCMT1zU2/U5“ function blocks provide all functions,
whilst the “TCMT1zB0“ function block only provides the
basic service “Send/Read Fixed Length Data”.
hThe “z” in the function block designation is the
placeholder for either a = asynchronous or
b = synchronous.

Data array size
11
02/02 AWB27-1300-GB
Data array size The size of the data arrays depends on the function block
type selected:
If the “TCMT1zB0“ or “TCMT1zU0“ function blocks are
selected, the data array is one-dimensional and is 1 to
220 bytes for send and receive data (afig. 3).
The data arrays in function blocks “TCMT1zU2“ and “U5“
are three-dimensional. These are defined by using the
parameters subaddress (0 to 255) and “offset address” (0 to
219) of type UINT (afig. 4). The third parameter specifies
the number of remote partner stations.
Separate data arrays are defined for all send and receive
data. In the example, the 256 send data arrays and 256
receive data arrays would be for the central station and one
send and receive data array for each of the 256 partner
stations. Ensure that the size of the send data array in the
central station is the same as the size of the receive data
array in the partner station and vice versa. In the example
therefore, the number of SD1send data units from the
central station must be the same as the number of RD1
receive data units of the partner station.
The maximum size of all data arrays in a station is approx.
6.5 Kbyte for PS4-150/-200 and 13 Kbyte for a PS4-300/
PS416. In a central station this available range must be
shared equally amongst all other stations of the telecontrol
line.

02/02 AWB27-1300-GB
With a PS416 or PS4-300 controller as the central station,
the maximum available range (send and receive data arrays)
is therefore calculated as follows:
When assigning offset addresses and subaddresses, make
sure that the maximum available data volume is not
exceeded.
Maximum data volume per partner station = 13 Kbyte
Number of partner stations in the telecontrol line
Offset addresses xSubaddresses (send data array)

These function blocks allow two stations to be connected.
The “TCMT1zB0“ function block supports service 17 (send/
read fixed length RAM data), whilst “TCMT1zU0“ supports
all services.

Assigning the data array
parameters
Default parameters
The function blocks are supplied with default parameters for
a data transfer of 20 bytes of send and receive data.
These data arrays are already set up in the variable
declaration of the function blocks. They may have to be
adjusted, however, if the default parameters are not exactly
as required.
One-dimensional data arrays for TCMT1zB0/U0
The function blocks have the following data array basic
settings and range limits:

VAR_OUTPUT
rec_dat: ARRAY[0..219] OF BYTE ;

1) Tra_sub_max/Rec_sub_max:
No subaddress is required as the data arrays are one-
dimensional. With variable length frames, the data entered
instead of the subaddress and offset address is transferred
transparently. This can be used on the partner station to check
the Subaddress value. If, for example, the sent “Subaddress”
value is less than the set address of the partner station, this
station will send a negative acknowledgement.
2) Tra_dfl_max/Rec_dfl_max:
Both parameters have default value 220, which can be adjusted
accordingly for the application concerned. The values for
“Tra_dfl_max/Rec_dfl_max” must be the same as the number
of offset addresses of the array “tra_dat/rec_dat”!
Example: Tra_dfl_max = 220 => tra_dat = 0 to 219
3) Fixed_length:
If service 17 is executed (send/read fixed length RAM data),
parameters xxx_dfl_max must ffixed_length.
