| Working with shakers undr the rules of e.g. ISO-9000 or GLP/GMP requires continuous monitoring of all influencing parameters such as temperature, humidity, shaker speed and CO2. For this reason all Kuhner machines are equipped with a CAN-bus (Controller Area Network).
This bus was developed by Bosch in 1983 for the car industry and has been accepted internationally (ISO standard) and European wide (EN-standard). The CAN-bus has distinguished itself with its robustness. General acceptance of the CAN-bus for the car industry and other industrial applications is undisputed. The reasons for the employing the CAN-bus in our shaking machines are the same as in the car: reduction of wiring (cost, errors) and very high flexibility.

CAN - USB
The USB-CAN module connects the CAN-bus of the shaker with the USB interface (universal serial bus) of a PC. In the meantime, the PC is equipped with an USB interface. The power supply of the USB-CAN module is via the USB-bus.

CAN - Ethernet
Internet communication via TCP/IP is also spreading into the industrial field.
Via a CAN-Ethernet-Gateway the CAN network of the shaking machine is being linked via the internet/Ethernet to your PC. For the communication a UDP/IP- based block transfer protocol (BTP) is used. With this the CAN- messages will be sent to the Ethernet with minimum delay. To connect to the external CAN network of the shaker, your PC simply needs a network connection via the Ethernet. CAN hardware is not necessary.
ISIS simultaneously manages up to 5 gateways (machines).

EMI-60 (External Machine-Interface)
The EMI module is plugged into the CAN connection (rear of machine) and firmly screwed on. The EMI possesses several interfaces:
|
1
|
RS-232 interface for the connection to your process-control
|
|
|
|
|
2
|
Analogue outputs with 0...5 volts.
|
|
|
|
|
2
|
Relays with switch-over contacts and programmable function for the connection of a process supervision.
|
|
|
|
|
1
|
Digital input for a 12...48V D.C. or A.C. signal with programmable function and galvanic separation.
|
|
|
NET-60 (for X- and W-shakers)
|
The module NET-60 connects your bus to the CAN-bus of the machine. NET-60 transfers as a gateway a subset of data to your system.
You have the choice of many standardized systems:
|
|
|
|
Bus: Physical layer:
|
|
+ Modbus/TCP Ethernet
|
|
+ EtherNet/IP Ethernet
|
|
+ PROFINET IO Ethernet
|
|
+ Modbus RTU R232 / RS485
|
|
+ PROFIBUS DP-V1 RS485
|
|
+ DeviceNet CAN
|
|
+ CANopen CAN

SSI = Shaker-Serial-Interface
SSI is a simple Demo-program for the Shaker-X interface to CAN-USB or RS232 via EMI-60. SSI runs on the operating systems: „Microsoft-Windows“ 2000 / ME / XP / Vista on any personal computer. SSI contains a detailled description of the interface protocol and the full sourcecode (VB.NET).
