Power Supply

You connect the power supply for the control logic via the four pin connector terminal X10 on the upper left side of the module.

Profibus Connector (X1):

Status Messages

Three LEDs provide information about the status of the module:

Power LED(+5V)

Bus LED (BF)

LED	Description
Green	Profibus Ok
Red	Profibus Error, Bus cabling incorrectly Configured the module wrong

Diagnostic

Address & Baudrate

Profibus Address

The Profibus adress is set by two rotary switch (S3 and S2) on the Buscoupler

Example: Address 34
S3 = 3
S2 = 4

Profibus Baudrate

The Profibus coupler detects automatically the Baudrate from 9.6 Kbaud to 12 Mbaud.

Assembly

You mount the Profibus base module off-center of the machine or in the control cabinet by simply fastening it to a device mounting DIN rail.
