Commissioning
7.1
Connectivity
Raman RunTime provides network-connected clients with analyzer data as well as analyzer control functions. Raman
RunTime supports Modbus and OPC connectivity. OPC UA is the recommended protocol because it allows transfer of
large data (full spectral data and diagnostics in this case) and is a more reliable connection than OPC Classic.
However, legacy support for OPC Classic (DCOM, also called OPC DA) clients is also built in.
The Raman Rxn4 system must be connected to a network for OPC functionality. Network settings can be viewed and
configured in Options > System > Network.
7.2
External circuit I/O panel
At the center of the rear panel, is an I/O panel that provides several extra low-voltage, non-intrinsically safe external
circuits:
•
Touchscreen. Type A USB 2.0 for connection to a local touchscreen display. This is not required for the
instrument to operate as all operation parameters may be set through the instrument's automation interfaces. A
touchscreen kit, which includes the interface cable for this connection, is available for purchase from
Endress+Hauser under p/n 70187807.
•
Display. Mini DisplayPort for video connection to a local touchscreen display. This is not required for the
instrument to operate as all operation parameters may be set through the instrument's automation interfaces.
This port does NOT support DP++; therefore, an active adapter is needed if connecting to a display without native
DisplayPort. A touchscreen kit, which includes the interface cable for this connection, is available for purchase
from Endress+Hauser under p/n 70187807.
•
Aux. Type A USB 2.0 reserved for future use.
•
RS-485. DB9 which provides a half-duplex serial RS-485, two-wire plus ground, Modbus RTU automation
interface. Pin 2 is Data +, Pin 3 is Data –, Pin 5 is ground. All other pins are inactive.
Recommended wiring is commercially available shielded, 2 twisted pair, 22 American wire gauge (AWG),
terminated with a DB9 receptacle and back shell kit. Endress+Hauser recommends Carol C1352A cable, TE
Connectivity 5-747905-2 receptacle and 1991253-9 back shell kit. Cable and connector/back shell of equivalent
specifications may be substituted. One pair is used for Data+ and Data– and one of the wires from the second
pair is used for ground. It is not recommended to use the shield as a signal ground. No provision for connecting
the shield drain is provided at the Raman Rxn4. The shield may be connected to earth at the device on the
opposite end of the cable attached to the Raman Rxn4.
•
Network 1. 10/100/1000 RJ45 Ethernet interface. Provides remote control option and automation data via OPC
UA, OPC Classic and Modbus TCP. Use standard ethernet cabling.
•
Network 2. Same as Network 1. Both interfaces may be used at the same time.
