1. Introduction
Scope of these instructions
These instructions are valid for SIMA Master Stations based on Compact PCI technology with
Actuator Software SimaSoft, version 1.06 to 2.10 (current version).
Please note that from ver. 2.00 on SIMA distinguishes for some field busses between protocol 1 and
protocol 2 in the communication to DCS. This regards the maximum number of actuators, 127
(protocol 1) and 247 (protocol 2). The used protocol is selected in SIMA.INI, see clause 1.1, p.30.
If there are no advices about protocols in this chapter, the used field bus to DCS does not have this
restriction.
New actuator type AC.2:
If not explicitly differentiated, does the term AUMATIC refer to both control variants: AC.1 and AC.2
Outline of the product
The actuator control system SIMA enables easy integration of AUMA actuators into various host
system solutions. System integrators do not have to take care of the field bus communication to the
actuators distributed in the field, this is done by SIMA.
SIMA has a modular design based on industrial personal computer technology. SIMA offers various
interfaces to communicate with its environment.
It may function as black box to collect all information from AUMA actuators distributed in the field
and to place these information in a concentrated form at the disposal of a high-level-control
systems.
Furthermore, SIMA can operate as standalone master providing higher-ranking functionality to
control AUMA actuators in the field.
A combination of both working as the client of a DCS and autonomously is also possible.
Since there are various fieldbus systems supported a system integrator can select the most suitable
way of communication and integration.
About SIMA operation instructions
For each combination of fieldbus to host and field, ie. actuators, a separate operation instruction is
available. There is also a separate instruction for customer specific implementations.
Regardless of which configuration will be delivered, every manual describes our complete well
coordinated redundancy concept (see 4.2, p. 9 or 6.1, p. 12).
Note: Differences or restriction regarding the various configurations are indicated by remarks or
footnotes. Chapter 7, SIMA Interfaces, however considers the SIMA station delivered and referred to
and therefore changes according, eg. the ordered fieldbus configuration.
