Presentation
The LMP-100 is a gateway that enables the integration of
the Profibus and Modbus industrial networks. By assuming
simultaneously the role of a Profibus DP slave and a Modbus
RTU master, it allows Modbus slaves to be controlled by
Profibus masters.
The LMP-100 may be mounted on a standard 35 mm DIN
rail. LEDs provide indication of power supply, device, Modbus
and Profibus network states.
The power and communication cables are connected by
fully detachable terminal blocks. The connection to the Profibus
network can also be made through a DB9 connector on the
frontal.

Typical Applications
The LMP-100 is typically used in applications where Modbus slaves need to be integrated
into a Profibus DP network. As an example, this scenario may occur in the following situations:
•Replacement of a Modbus-based installation with a Profibus-based one, reusing the
Modbus devices.
•Necessity of using a particular device only available with Modbus communication in
Profibus-based facility.
Figure 1 depicts a LMP-100 typical application. In the role of a Profibus DP slave, the
LMP-100 receives commands from the Profibus master. These commands are interpreted by
the LMP-100 which, in the role of a Modbus master, forwards them to the Modbus slaves.
Similarly, the LMP-100 periodically scans the Modbus slaves for field data, which are interpreted
and sent to the Profibus master.
The mapping between Profibus and Modbus inputs and outputs is configurable through a
concept called “Modbus rule”.

Frontal
LED
Color
Description
PWR Green (Power) Indicates power supply operation. Continuously lit LED
indicates proper power supply operation.
RUN Green
(Run) Indicates proper operation of the device. After the device is
energized, the LED will flash 5 times. If the self-test boot routines
succeed, the LED remains lit, indicating proper operation of the device.
If the LED is turned off, a critical error occurred at startup, and in this
case the device will no longer operate correctly.
BF Red (Bus Fail) Indicates failure in the Profibus network. When lit means that
the LMP-100 is not in the “Data Exchange” state.
ST Red
(Status) Indicates presence of failure or diagnostics. The failure is
indicated by the frequency at which the LED flashes. When lit
continuously, indicates the presence of diagnostic information.
TX Orange Indicates data transmission over the Modbus network.
RX Green Indicates data reception over the Modbus network.
