4. SIMA System Configuration

4.1. Standard Configuration – System Chart

A standard setup consists of the host system, eg. a DCS, of at least one SIMA Master Station and the

actuators (or other field devices), each connected by a standardized fieldbus.

SIMA itself is based on standard industrial PC hardware equipped with all necessary fieldbus

interfaces according to the required environmental conditions.

The SIMA basic version will be operated by means of peripheral devices (monitor, keyboard, or

mouse)

The SIMA touch screen version displays the HMI (actuator overview, actuator faceplates, settings

etc.) on the integral screen and can be operated by it (touch sensitive). More details s. below.

System charts for two example SIMA configurations:

Minimal configuration

SIMA basic version with a single bus

version to field (chA) and Host (DCSA)

Full redundancy in Hot-Stand-by

SIMA touch screen version with to bus lines to field

(chA, B) and host (DCS A,B) synchronized to a

Stand-by-SIMA

Host system (DCS)

SIMA collects all necessary information from the actuators by using a standardized fieldbus protocol

such as Modbus or Profibus DP and makes this information available to the host system in a

concentrated form. In addition, SIMA operates and controls the whole fieldbus communication to the

actuators.

In case the host system is not yet available or not necessary at all it is possible to operate all

connected AUMA actuators with SIMA for test purposes or to bridge the time until the host system is

ready for operation.

Moreover this stand-alone operation (without a DCS, or others) is an outstanding feature of SIMA,

particularly useful for projects at medium complexity.
