The bus master can remotely control the SIGMA CONTROL 2.
8.11.4 Interconnection of two machines in master/slave operation
Example 1 Two machines with different flow rates
A time program that can be configured on the master switches between the
pA and pB set-point
pressures. The machine with the high flow rate is the master and the machine with the lower flow
rate is the slave.
■ Operating mode of load control on master:
Local mode pA/pB Clock.
─ During periods of peak demand of compressed air, the master is regulated (in accordance
with the time program) to the set-point pressure
pA and the signal for using the set-point
pressure
pB is transmitted to the slave.
─ During periods of low air demand, the master is regulated (in accordance with the time pro‐
gram) to set-point pressure
pB (e.g. at weekends). The slave receives the information, to
use set-point pressure
pA now.
■ Operating mode of load control on slave: Remote mode pA/pB SC2.
─ At peak air demand times, pressure is regulated to the
pB set-point pressure and at times
with low air demand to set-point pressure
pA.
─ At times with lower compressed air demand, the machine is correspondingly used more fre‐
quently.
Example 2: Two machines with equal flow rates
A timer that can be set on the master switches between the
pA and pB set-point pressures. The
set-point pressures
pA and pB are set the same for both machines.
■ Operating mode of load control on master:
Local mode pA/pB Cycle.
─ The timer ensures even loading of both machines.
─ E.g. if the first start
pA is selected as the start time, the master regulates for cycle time 1 at
set-point pressure
pA and sends the slave the signal to use set-point pressure pB. During
cycle time 2, the master regulates to set-point pressure
pB and signals to the slave to regu‐
late to set-point pressure
pA. .
■ Operating mode of load control on slave:
Remote mode pA/pB SC2.
─ Depending on the specification by the master, the slave regulates to set-point pressure
pA
or pB. See example for the master:
Cycle time 1 = set-point pressure
pB
Cycle pressure 2 = set-point pressure
pA
