5.3 BUS INTERFACES (OPTION)
The control device of Thyro-P may be optionally fi tted with interface cards for interfaces customary
for the industry. In case of bus systems not listed, please enquire about availability.
5.3.1 PROFIBUS-DPV1
With a Profi bus interface card (order no. 2000000393) it is possible to connect the Thyro-P to a
wide ranging Bus system. For use of Thyro-P in an automation network with SIEMENS PCS7,
software modules are available (at SIEMENS).
The Profi bus slot card is plugged into the front of the control device and is immediately ready to
operate after parametrization. In case of Profi bus control, the control device should be supplied
separately, so that should the power supply be switched off, the Power Controller is not interrupted
resulting in an alarm message. The connector supplied must be removed (see chapter 4.2).
Three 24V inputs are additionally available, which may be polled via Profi bus (for instance for swit-
ching state, power interruptor, monitoring the cabinet ventilator, monitoring the cabinet door, etc.).
The Profi bus option includes
• 1 Profi bus slot card
• 1 diskette for confi guration of Thyro-P as Profi bus slave,
• 1 covering frame for secure fi xing of the slot card,
• 1 short instruction booklet
ATTENTION
The mounting of the option must be made in voltageless state.
GENERAL
Up to 125 slaves may be connected to a Profi bus system. 32 slaves are possible for each Profi bus
segment. Coupling of individual segments is performed using so-called repeaters. Profi bus systems
may be organized as line, bus or tree structures. Besides the usual electrical connections (RS 485
technology), it is possible, for instance in highly interfering environment (magnetic fi elds, etc.) to
use fi bre optic as transmitting medium.
The line length depends on the respective transmission rate and is possible up to 1200m (also refer
to the table).

PROFIBUS SLOT CARD
The Profi bus slot card (about 86 x 70 mm) has two 9-pin SUB-D sockets on the front side. On the
other side, there is a 9-pin SUB-D plug to be inserted into the Thyro-P control device. The Profi bus
slot card for instance contains driver circuits, galvanic separation for the bus circuit as well as a
microcontroller for controlling bus access and other functions.
