Applications
The T400 is a technology module. It can be used to complement drives with sophisticated, high-dynamic
performance open-loop and closed-loop control functions at a favorable price. Sampling times down to 100 µs
are possible.
Applications include higher-level closed-loop controls for:
•closed-loop tension control
•closed-loop position control
•winder and coiler
•(angular) synchronous control
•positioning
•cross cutter and flying saws
•drive-related open-loop control functions
The T400 can be inserted in the electronics box of
•SIMOVERT MASTERDRIVES VC, MC Compact 6SE70/71 AC drive converters (not in MC Compact PLUS!)
•SIMOREG DC-MASTER 6RA70.
Further, the T400 can also be used in the SRT400 SIMADYN D subrack. Two T400 can be inserted in the
SRT400.
The T400 is always used in the drives and in the SRT400, together with the MASTERDRIVES or DC MASTER
communications module, for example, CB1, SCB as well as the ADB carrier module with the communications
modules inserted in it, for example, CBP2 (PROFIBUS-DP), CBC (CAN), CBD (DeviceNet).

 2 binary outputs
 8 binary inputs
of which 4 binary inputs can be used to call interrupt tasks (50 µs response time)
 4 bi-directional binary inputs or outputs
 2 incremental encoder inputs with zero pulse
- encoder 1 for HTL (15V) encoder
Encoder pulses of an encoder connected to a SIMOVERT MASTERDRIVES SC/VC which are fed
via the backplane bus to the T400 can also be evaluated. This means it is also possible to use a
TTL/RS422 encoder. The pulse encoder simulation via the backplane bus of the SIMOVERT
MASTERDRIVES MC can also be used.
- encoder 2 for HTL (15V)- or TTL/RS422 encoder (5V)
 For each incremental encoder, a coarse pulse input to suppress the zero pulse, the coarse pulse input
(simultaneously) can also be used as binary input.
 The inputs/outputs are not electrically isolated
 2 absolute value encoders with SSI- or EnDat protocol (RS485) for positioning applications
Note: When using absolute value encoder 2, serial interface 2 (peer, USS) cannot be used, as the
same terminals are used for the two applications!
Serial interface 1 with RS232 or RS485 data transfer format;
The protocol can be selected using a switch on the module:
 Service protocol DUST1
for start-up (CFC test mode, service IBS (start-up), TELEMASTER) and downloading programs
with a 19.2 kbit/s baud rate at the RS232 interface
 USS protocol,
2 wire, with selectable RS232 or RS485 data transfer format;
max. baud rates, 38.4 kbit/s;
can be configured as slave for parameterization with OP1S (from OP1S, version V2.2),
or as master for the OP2 operator panel connection
Serial interface 2
with RS485 data transfer format, selectable baud rates of: 9.6; 19.2; 38.4; 93.75 and 187.5 kbit/s;
the required protocol is selected by appropriately configuring the function block:
 Peer-to-peer
for fast process coupling, 4 wire
 USS protocol (USS bus),
can be configured as slave for parameterization with SIMOVIS (2- or 4 wire),
as master for OP2 operator panel connection (2 wire) or to control drive converters;
max. baud rates, 38.4 kbit/s;
Low deadtimes can be achieved as a result of synchronization:
 Synchronization of the T400 on the basic drive converter modules (CUx) or second T400
 T400 supplies synchronizing signals for other modules (CUx, CBx or second T400)
Other features
•Lowest sampling time is 0.1 ms, 0.8 ms is the typical sampling time for a control loop
•As a result of the floating point arithmetic, not only is a high accuracy achieved, but configuring is also
simplified as normalization and value range limits are eliminated
•Operation without fan
•3 LEDs for operating status displays
•Hardlock-PAL: Plug-in socket for 28-pin EPLD device for copy protection of the user program
•Soldered-in flash memory (2 Mbyte) for the program code (compressed), which is downloaded from the PC
via the serial interface; no plug-in memory module is used!
•4 Mbyte DRAM as working memory for programs and data,
•32 Kbyte permanent change memory
•NOVRAM for data save at voltage-off for up to 10 configurable values (real type)
•Cache memory: 4 Kbyte program, 4 Kbyte data

3.6. Absolute value encoder
The T400 has up to 2 synchronous serial interfaces for absolute value encoders:
Input voltage range RS422, 5V
Encoders which can be
connected Single- or multi-turn encoders
SSI (synchronous-serial)
Protocols EnDat (accord. to the Heidenhain company)
Data transfer rate 100kHz to 2 MHz
Dual code
Grey codeData representation type Grey excess code
It is possible to simultaneously use the 2 serial interfaces and absolute value encoder 1 (terminals 76-79).
3.7. Serial interfaces
The T400 has 2 serial interfaces:
3.7.1. Service interface 1
Interface 1 has the two physical versions (they can only be used one at a time!):
•RS 232 for PC coupling (download, service, via the Dust1 protocol with 19.2 kbaud)
•RS 485 (2 wire) for USS to connect
-SIMADYN D OP2 operator panels
-MASTER DRIVES OP1 operator panels
-SIMOVIS
-or to the higher-level (master) / systems (e.g. SIMATIC)
The program is downloaded and service for start-up executed via interface 1. To realize this, the CFC is used in
the test mode or service-IBS V5 (service start-up) (DUST1 protocol, baud rate: 19.2 kbd).
3.7.1.1. Communications switch S1/8
The physical version of serial interface 1 can be selected using S1/8.In addition to the changeover, the
appropriate blocks must have been configured for the USS protocol. If the USS protocol is set, it is no longer
possible to realize online visualization with CFC or service-IBS (service-start-up)!
Switch S1 / 8
ON RS485 (2 wire) for USS protocol (bus termination, refer to 3.7.3)
OFF RS232 for service / start-up

3.7.1.2. Connecting cable to the PC
The connection between the T400 and the configuring-PC is via a serial link; this is established using the
following cable which the user must assemble. Switch S1/8 must be in the OFF position.
The cable can be ordered as SC400 with the order number 6DD1684-HF0.

3.7.2. Interface 2
Interface 2 is a mixed asynchronous and synchronous RS 485 interface:
•Peer-to-peer with full duplex, 4-wire connection
•USS protocol (master or slave) with half duplex, 2-wire connection
The function blocks @USS_M,@USS_S or @PEER are used to toggle between 2- and 4- wire operation. As soon
as one of these blocks is configured, terminals 72 to 75 can no longer be used for an absolute value encoder.
The following baud rates can be set:
Peer to Peer: 9.6 kbd, 19.2 kbd, 38.4 kbd, 93.75 kbd, 187.5 kbd
USS: 9.6 kbd, 19.2 kbd, 38.4 kbd
3.7.3. Bus termination switches S1/1 - S1/6
The bus terminating resistors for serial interfaces 1 and 2 must be switched-in via switches S1/1 - S1/6, if the
T400 is located at the beginning or end of the RS485 bus. If it located in the center, it is not permissible that the
terminating resistors are switched-in.
Terminals Switch S1
Serial interface 1 70 / 71 1, 2
Serial interface 2 (2-wire) 74 / 75 3, 4
Serialinterface2 (4-wire) 72/73/74/75 3,4,5,6
In the ON position, the terminating resistors are switched-in.
The switches can only be switched when the module is withdrawn. They
are not accessible when the module is inserted.
3.7.4. Download switch S1/7

3.8. Diagnostic LEDs
Three diagnostic LEDs are located on the T400.
LED H1 displays the status of the internal T400 monitoring
function. Under normal operating conditions it flashes slowly,
approximately every second (1.5 Hz).
If H1 starts to flash at a average rate (with 2.5 Hz) this indicates an
internal fault/error. Possible faults/errors are:
•user stop
•communications error
•computation time overflow
•hardware monitoring fault
The user stop can be initiated using the CFC- or the configured
software. If the T400 is inserted in an electronics box, generally, the
basic drive converter module signals a fault if the T400 is in the
user stop status.
If there is no user stop, the module must be accessed using the
CFC in the test mode or with Service-IBS V5, to precisely
determine the cause and to evaluate the internal fault fields.
If H1 flashes quickly (with 5 Hz), this indicates an initialization
error. The T400 program is either erroneous, or switch S1/7 is in
the ON setting.
If H1 goes into a steady light condition this indicates a system
error. The user program is not processed. The T400 is either
defective or has been incorrectly programmed.
The module must be accessed using the CFC in the test mode or
with the service-IBS V5 to precisely determine the cause, and to
evaluate the internal fault fields.
LEDs H2 and H3 indicate the coupling status to other modules. A
uniform flashing indicates an error-free coupling. The flash
frequency of H2 and H3 is determined by the configuring, i.e. the
sampling time of function block @DRIVE.

Parameterization
18 Edition 04.00 Siemens AG
SIMADYN D Hardware Brief Description
5. Parameterization
All parameters, which refer to the functions and settings of the T400 technology module, are called
technological parameters. They lie in parameter ranges between 1000 and 1999 and between 3000
and 3999 (if used).
Depending on the access type, thousands are represented directly, or as letter. In this case, there is
an additional differentiation between visualization and parameters which can be changed.
The number and the function of the individual technology parameters is dependent on the configuring.
Range Display Example Significance
1000 ... 1999 Hxyz H234 Parameter No. 1234 which can be changed
1000 ... 1999 dxyz d411 Visualization parameter No. 1411 (this cannot be
changed)
3000 ... 3999 Lxyz L234 Parameter No. 3234 which can be changed
3000 ... 3999 cxyz c521 Visualization parameter No. 3521 (this cannot be
changed)
The technological parameters can be read and changed (simultaneously) from several locations:
•PMU
•OP1, OP1S (the configured parameter names are displayed)
•CB1 (PROFIBUS)
•SCB2 with USS protocol
•Serial interfaces 1 and 2 of the CU
•PC/start-up program (SIMOVIS)
All parameter changes are stored in a EEPROM. This EEPROM allows a maximum of 100 000 write
accesses. This limitation must be taken into account, if frequent write accesses, e.g. from a PLC via
PROFIBUS or USS are used, e.g. with continuos commands to ‘store permanently in EEPROM’. For
continuos changes the command ‘store temporary in RAM’ should be use.
