KINCO

Note: for project configuration of BRIDGE, you must configure DI/D0 resource of 12 bytes firstly.

AI/AO is optional.

（5）Must Use OB82,OB86,OB100,OB121,OB122 in the ladder program of the external

device, otherwise you need to manually operate the RUN switch of the external device as

“RUN,STOP,RUN” in this order upon restart the display or PLC. When you use those special OB

block, the communication will be automatically recovered even if you restart the display or PLC.

（6）Save and compile, and download to module, then the light of profibus is on.

（7）After configuration, and then you can program.

Bus Bridge setting:

（1） Setting ID of Profibus by switching 8-bit Dip(DIP1 is lowest bit, DIP8 is highest bit),range

is from 3 to 125;

ID must be the same as its configuration in Siemens software. As above picture for example,

setting is “3”, that the switch DIP1 and DIP2 on the panel of profibus are set ON, others are OFF.

（2）Profibus support baudrate as follows: 9.6Kbit/s, 19.2Kbit/s, 45.45Kbit/s, 93.75Kbit/s,

187.5Kbit/s, 0.5Mbit/s, 1.5Mbit/s, 3Mbit/s, 6Mbit/, 12Mbit/s，and interface is automatically adaptive.

（3）A cable (purple),connect DP interface of s7-300 and bus bridge of profibus. Two sides

have active terminal resistors; Switch on the s7-300 PLC is off, on the busbridge is on.

（4）Setting baudrate of modbus by switching DIP1-3 of modbus ID port, support 8 kinds of

baudrate .Setting as follows:

1 2 3 Baud

OFF OFF OFF 1200

ON OFF OFF 2400

OFF ON OFF 4800

ON ON OFF 9600

OFF OFF ON 19200

1 2 ... 71 72 73 74 75 76 77 78 79 80 81 ... 257 258
