PROFIBUS
General
The Profibus allows to communicate with the controller
as Profibus DP slave device.
The option works as a bi-directional bridge between the
Profibus network and the Varian turbo controller internal
link. The interface provides input data (measures) and
output data (commands) to the controller, and in addic-
tion provides standard and user related diagnostics, in
order to allow the user to manage the exceptions.
NOTES
Insert only one module in the configuration of the
TV 301-P Navigator Controller, even if it can accept up
to four modules.
Mechanical
The Profibus interface is mounted on the bottom side of
the controller.

Installation
The ProfiBus connector pin-out is reported in the fol-

ance use ProfiBus certified cables
CAUTION
To maintain the IP-54 protection level, use the appropri-
ate connector provided with the pump.

Configuration
Before power-on the controller set the Profibus address
by the 2 rotary switches.
Up to 126 different addresses (from 0 to 125) can be
selected. The address value sets by the 2 switches is
expressed in hexadecimal notation, so value from 00 to
7D are permitted; this setting is read by the interface
during the power-on phase, so any change of the switch
position after the power-on is ignored.
Before power-on the controller place the special mating
connector on the serial connector J6 in order to ensure
the communication between the internal link and the
Varian turbo controller.
Indicators
Two LEDs are present on the interface: one green and
one red:
•
the red led indicates that the interface is correctly
powered;
•
the green led shows the interface status according
the following table:
--------------- 550 ms period------------------
1 pulse
2 pulses
Blink fast
Blink slow
1 pulse
ProfiBus link established, controller link NOT es-
tablished yet (Controller state machine not in
Regular data exchange). This situation could be
normal in the first 45 seconds after the interface
power on (Controller address searching phase) or
after the controller power-on.
You have this error if the special mating connector
is not placed on the serial connector J6 (see para-
graph "Configuration").
2 pulses
ProfiBus link not established yet (ProfiBus state
machine not in Regular data exchange). This fail-
ure has priority (in the indication) over the previ-
ous.
Blink fast
Gateway fail (internal check) or wrong address set
(address > 0x7D or address not stable during
power-on).
Blink slow
Gateway operating properly.
