KAESER SIGMA CONTROL 2 Service Manual

When all requirements are met, perform the commissioning process for each communication
module as shown below.
The following description concerning the parametrisation refers to current
SIGMA CONTROL 2 software versions. Please contact KAESER SERVICE if the settings in
the machine deviate.
8.7.3.2 Commissioning the PROFIBUS module
Machine
1. Open the 8.2 <Communication – Com-Module> menu.
2. Activate the Com-Module Start check box.
The communication module is activated. The system detects the communication module type
and displays it in the Type line.
3. Select the data exchange direction:
► SIGMA CONTROL 2 ⇆ Bus master (SIGMA CONTROL 2 sends process data and receives
control data): Send/Receive or Master : Set Com-Module .
► SIGMA CONTROL 2 → Bus master (SIGMA CONTROL 2 sends process data): Send or
Master : Setting SAM/JSON-RPC .
For connection to a SIGMA AIR MANAGER: Send/Receive or Master : Set Com-Module .
4. Set the slave address ( Slave No. :). The permissible address length is between 3 and 126. For
connection to a SIGMA AIR MANAGER: Slave address = compressor number + 102.
5. Set the required reaction in the event of a bus fault (see next chapter, “Reaction in a PROFI‐
BUS bus fault”).
6. Start the communication module with the set parameters. Activate the Reset check box.
The communication module is started with the set parameters.
7. Time-out at bus fault is activated.
Bus communication is now monitored.
The number behind Status Counter (Run ) continuously changes during communication.
Reaction in a bus fault
Only for machines.
After switching on the power supply, the bus alarm can be suppressed for a definable period of
time. The setting depends on the time passing at the bus master between return of voltage and
start of communication via the bus.

Tab. 66 Setting the Starttd parameter
SIGMA CONTROL 2 monitors the bus communication at log level (PROFIBUS). If there is a check
box behind Communication error , this monitoring in the Send mode can be switched off by deacti‐
vating the check box.
