This is a DeviceNet System Configuration.
SyCon is the DeviceNet configuration tool. And target devices are ALD112, DeviceNet and DeviceNet devices.
SyCon support debug function for DeviceNet,too.
SyCon can be installed in the same PC where the CS3000 System builders are installed.
When Sycon is installed to the same PC of the CS3000 system builders,
the operating system of the PC should be Windows 2000 Server.
To prevent from collision of communication, it is recommended to use switching hub and to segregate the Ethernet network in to independent ALD112-Sycon and ENG-HIS Ethernet networks.

7. Positioning of DeviceNet Interface Module
One of sub-system interface of CENTUM CS3000.
DeviceNet interface module (Model ALD112) is newly introduced in the same form of FIO.
ALD112 works as protocol converter between ALE111(Modbus/TCP) and DeviceNet.
CS3000 R3 system provide ALD112(DeviceNet Interface Module) with FIO family.

(2)Relation between DeviceNet and CAN(Controller Area Network) bus DeviceNet is based on the CAN bus, and the specification is added to this. The CAN bus is a reliable bus used in the auto sector.
(3)Bus access method The device that started communicating first on the bus has the priority to keep communicating. When there are two devices that start communicating at the same time, the device with priority can keep communicating by looking at the pattern of 11 bits (packet ID) at the head of the communication frame. This is CSMA/NBA (Carrier Sense Multiple Access with Non-destructive Bitwise Arbitration）Method
(4)Device profile EDS (Electric Data Sheet) is defined in the DeviceNet specification. This is an easy file format, and other venders can acquire the specific information on the product.
