Functions of the SIMA² software
Automatic display of the most important status information of SIMA², as well as the connected actuators
immediately after switching on (once commissioning and definition of the system configuration is com-
plete).
Web based user interface for oper-
ating and monitoring SIMA²
Password-protected access to settings and entry of manual operation commands for the actuators.
Control of connected actuators.
Visualisation of feedback from connected actuators.
Optional specification of the individual designation for each actuator.
Actuator identification via the user
interface
Setting the communication between SIMA² and actuators (e.g. redundancy, baud rate, parity, port
number, number of actuators, highest field device address).
Adapting the communication charac-
teristics via the HMI user interface
Setting the communication between SIMA² and DCS (baud rate, parity, number of stop bits, address,
monitoring time, IP address, subnet mask, port, unit ID).
Monitoring and visualising the communication status with the DCS
Communication monitoring
For redundant communication to the DCS:
Two communication channels with equal access rights.
Support, monitoring and management of redundant communication to the DCS (option), the hot standby
system redundancy (option) and the redundant communication to the actuators (option). Upon occurrence
of a fault, the function is immediately adopted by the redundant communication channel or the redundant
system without any interference.
Redundancy functions
Administration of different communication protocols of the DCS and the actuators, e.g.: Modbus TCP/IP
<> Modbus RTU or Modbus TCP/IP or Modbus RTU)
Gateway function
Implementation of various solutions for communication to the DCS and communication to the actuators
(e.g. single-channel communication for DCS <> redundant ring topology or redundant line topology to
the actuators)
Data interface to host
Output data (operation commands) to the actuators connected to SIMA²
Output data from DCS to SIMA²
Input data (feedback signals) from the connected actuators as well as additional status information of
SIMA²:
●
Communication status to the actuators
●
Communication status to the DCS
●
Number of currently available actuators
●
Deviation from the planned number of actuators
●
In case of a fault of the Modbus ring topology: Fault location within the ring
