8.10 Configuring the machine for master control
8.10.1 Overview of the different master operating modes
The controller offers several possibilities to work together with other controllers:
Method Description Section
Interconnected operation with
SAM 4.0.
The operating mode settings on the SIGMA
CONTROL 2 must be changed via a
SIGMA NETWORK to enable control by a
SIGMA AIR MANAGER 4.0.
8.10.2
Interconnected operation via
PROFIBUS
(only available with SIGMA
CONTROL 2 - prepared for connection
to control technology with optional
communications module).
The controller (and therefore the machine) re‐
ceives the instruction LOAD or IDLE
12)
via the
PROFIBUS master (e.g.
SIGMA AIR MANAGER). The system setpoint
pressures pA and pB are irrelevant for activated
LOAD/IDLE signals.
8.10.3
Interconnected operation of two com‐
pressors with SIGMA CONTROL 2 via
Ethernet interface.
The two SIGMA CONTROL 2 controllers oper‐
ate as master and slave. The slave receives the
command to switch between the two system set‐
point pressures pA and pB from the master.
