AUMA SIMA 2, Руководство пользователя

Страница: 9 / 44

In case of interruption or short-circuit within the loop system, communication to the
actuators is maintained.
AUMA redundancy As an alternative to loop redundancy, the fieldbus connection to the actuators can
also be designed as line topology. In this case, two separate fieldbus cables are
installed in line topology to each actuator.
Auto configuration Automated procedure during commissioning of loop redundancy whereby the fieldbus
addresses are automatically assigned on the basis of the actuator sequence within
the loop.
Network Physical arrangement of actuators connected to SIMA² (line topology or loop
topology). With Modbus RTU, up to 247 actuators are supported for each SIMA²
network.
2.2. Name plate
Data for identification Each SIMA² is equipped with a name plate. The name plate is located at different
positions: for rack mounting or as bench device on the rear, for devices in wall
mounting version at the left side of the device.
For unambiguous assignment of SIMA², the following data is required:
Figure 5: Data for identification
[1] SIMA² PO number
[2] Order number
[3] Wiring diagram number
[4] Power supply
[5] Equipment of fieldbus interface to the DCS
[6] Equipment of fieldbus interface to the field devices
[7] Redundancy
[8] Serial number of SIMA A
[9] Serial number of SIMA B
[10] Identification number (system name)
Information
The numbers can be directly read on the display via the SIMA² menu and sub-menu
Info .
[1] SIMA² PO number
SIMA² PO number encodes the device’s hardware configuration.
[2] Order number
This number is used to request any order-related information.
[3] Wiring diagram num-
ber
Assignment of SIMA² wiring diagram is specified by the configuration of the fieldbus
interfaces and can be identified from the PO number on the name plate.
