Communication; Configuration Using The Trovis-View Software - Samson 3730 Series Mounting And Operating Instructions

Leakage sensor
By upgrading the positioner with a leakage
sensor, it is possible to detect seat leakage
when the valve is in the closed position.
Binary input BI1 (14)
As a standard feature, the positioner comes
with a binary input used to signalize process
information over the F
network.
Binary input BI2 (15)
This binary input BI2 is optional. It is an ac-
tive input which is powered by the positioner
to connect a floating contact. The switching
state of the floating contact can be indicated
over the F
OUNDATION
Note
The binary inputs are configured in the DI
Function Blocks. Refer to Configuration
Manual KH 8384-5.

3.3 Communication

The positioner is controlled completely by
digital signal transmission according to
™ fieldbus specification.
F
OUNDATION
Data are transmitted over the bus using digi-
tal, bit-synchronous Manchester coding at a
Baud rate of 31.25 kbit/s over twisted-pair
wires according to IEC 61158-2.

Design and principle of operation
Note
If complex functions are started in the posi-
tioner, which require a long calculation time
or lead to a large quantity of data being
saved in the volatile memory of the position-
er, the alert 'busy' is issued over the DD. This
alert is not an error message and can be
simply confirmed.

3.4 Configuration using the
TROVIS-VIEW software
The positioner can be configured with
SAMSON's TROVIS-VIEW Software.
The positioner has for this purpose a serial
interface to allow the RS-232 or USB port of
a computer to be connected to it using an
adapter cable.
The TROVIS-VIEW software enables the user
to easily configure the positioner as well as
view process parameters online.
Note
TROVIS-VIEW provides a uniform user inter-
face that allows users to configure and pa-
rameterize various SAMSON devices using
device-specific database modules. The de-
vice module 3730-5 can be downloaded
