DeviceNet Master Connection

11.2 Setting of the I/O Address

The total length of the bus cable depends on the cable type or on the
transmission rate and must not exceed the following lengths:
Baud rate
Thick cable
125 kbits/s 500 m
250 kbits/s 250 m
500 kbits/s 100 m
Fig. 11-2: Maximum cable lengths dependent on the used cable
Note: To ensure that the function of the DeviceNet interface is
faultless, use only cable according to the DeviceNet
specification. Furthermore, it is obligatory that both cable ends
of the bus segment are terminated with 120 Ohm.
Individual branch lines must not exceed a length of 6 m. The total length
of all branch lines must not exceed 156 m for 125 kbaud, 78 m for 250
kbaud and 39 m for 500 kbaud.
The configuration and commissioning of the LK DNM03 occurs by the
system configurator
SYCON****DN). It communicates via a serial connection between the
COM port of the PC and the diagnostic interface X84 of the LK DNM03.
The configuration is stored on the LK DNM03 and is thus immediately
available when it is started.
The technical data of the LK DNM03 are as follows:
• Process image with maximum 7 kbytes (inputs and outputs)
• 16 bit processor with interrupt and DMA controller
• 8 kb DPM, 512 kb flash and 128 kb RAM
• CAN controller SJA 1000
• Isolated DeviceNet interface according to ISO 11898, max. 500 kbaud
• Non-isolated diagnostic interface RS232C, 9600 Baud
The setting of the start address occurs via jumpers of the plugboard J4.
Thereby, the corresponding address line is specified besides every plug-
in jumper.
When using the board in conjunction with WinPCL the starting address
has to be set as follows (X = jumper plugged in).
