CONTROLLER COMMUNICATIONS
(MASTER/SLAVE & MULTIUNIT SYSTEMS)
GENERAL INFORMATION – LOGIK9
Logik9 has 1 RS485 serial communication port that allows to communicate under ;
• Master / Slave Mode : the communication between two compressors
• Multiunit : the communication between compressors up to 12 units
• Scada Systems : Logik9 can communicate with scada systems by using Modbus RTU
• Cloud Server : Logik9 can pass the information to cloud and user can follow the
compressor by using webbrowser
• Webserver : Logik9 and by using special ethernet serial gateway, user can observe the
compressor information on the webserver.
GENERAL INFORMATION – LOGIK26S
Logik26S has 2 RS485 serial communication ports. Second communication port can be used to
communicate with inverter driver itself.
The main communication port can communicate under the system described below;
• Master / Slave Mode : the communication between two compressors
• Multiunit : the communication between compressors up to 12 units
• Scada Systems : Logik26S can communicate with scada systems by using Modbus RTU
• Cloud Server : Logik26S can pass the information to cloud and user can follow the compressor by
using webbrowser
• Webserver : Logik9 and by using special ethernet serial gateway, user can observe the compressor
information on the webserver.
Note: If the compressor is not communicating with the driver, second RS485 port also can be used
to communicate with external modules & scada system as well.
GENERAL INFORMATION – LOGIK33S
Logik33S has 2 RS485 serial communication ports. Second communication port can be used to
communicate with inverter driver itself.
The main communication port can communicate under the system described below;
• Master / Slave Mode : the communication between two compressors
• Multiunit : the communication between compressors up to 12 units
• Scada Systems : Logik33S can communicate with scada systems by using Modbus RTU
• Cloud Server : Logik33S can pass the information to cloud and user can follow the compressor by
using webbrowser
• Webserver : Logik9 and by using special ethernet serial gateway, user can observe the compressor
information on the webserver.
Note: If the compressor is not communicating with the driver, second RS485 port also can be used
to communicate with external modules & scada system as well.
Communication / Master - Slave
Master / Slave communication functions :
• Balance Hours : Two compressors can be managed to balance the working hours
• Cascade working system with two compressors : By proper parameter settings user can
design cascade system where one compressor capacity is not sufficient to provide
pressurized air.
• Two inverter controller compressor can modulate at the same time by using special
inverter twin function (Logik 26S & Logik33S systems).
