INSTALLATION
4.1.4
Redundancy
If a redundant solution is required for increased availability, two Flow-X modules can be
used per metering run. Two identical SICK Flow-X/P enclosures working in redundant mode
can be used to attain maximum availability.
All modules have an integrated dual 24 V power supply.
4.1.5
Fast data exchange
Flow-X modules located in a SICK Flow-X/P enclosure can exchange the data quickly with
the neighboring Flow-X modules via Ethernet. This is the so-called multi-module operation.
As an example, a module is used that communicates with a gas chromatograph and makes
this data available to four other modules and also serves as a Modbus slave to a central
DCS connection.
Each Flow-X module can use the data from other modules as if it exists in its own data
space. SICK Flow-X/P has two dedicated Ethernet switches for this purpose. Alternatively, it
is possible to set up a Modbus TCP/IP link using Ethernet to exchange data between the
modules.
4.1.6
Display requirements
The Flow-X/P and Flow-X/C touchscreen supports effective and user-friendly data display
and navigation through the menu structure. Multiple languages are supported.
This display function is not always required. Each individual module is equipped with a local
black and white graphic display, which enables data display and parameter setting in the
module itself. The display supports 4 to 8 lines for data and/or parameters.
Apart from these physical displays, each module contains a web server that makes it
possible to display pages that can be accessed with a standard web browser via Ethernet.
4.1.7
Power supply
All Flow-X modules require 24 V DC and have integrated support for redundant power
supply.
