1. Introduction
1.1. Overview
PROFIBUS is an open, digital communication system with a wide range of applications, particularly in the fields of factory automation and process automation. PROFIBUS is suitable for both fast, time-critical applications and complex communication tasks. PROFIBUS-DP is a famous protocol that enables simple, fast, cyclic and deterministic process data exchange between
Master and assigned Slave.
The PROFI-2510 is a PROFIBUS repeater used to establish a physical coupling of two or more segments of a CAN bus system. According to the
PROFIBUS specification, up to 32 PROFIBUS devices are allowed per segment. Connecting via PROFI-2510, the division of a PROFIBUS system into several subsystems increases the maximum number of bus nodes.
The PROFI-2541 is a PROFIBUS to Fiber Converter and it is the economic solution for applications which require protecting the data transmission from electrical exposure, surges, lightning or chemical corrosion.

2. Hardware
2.1. Bus Wiring
In order to minimize the reflection effect of the signal transmission,
PROFIBUS device has to fit with an active terminal resistor at both first node and last node, as shown below
However, the number of station in PROFIBUS network is also restricted.
According to PROFIBUS specification, it is up to 32 stations connected in a
PROFIBUS segment. If more than 32 stations are connected, the PROFIBUS repeater must be used to link the individual bus segments.

2.2. PROFIBUS Cable and Transmission Distance
The PROFIBUS cable with following properties has different transmission distance with respect to different transmission rate, shown in the following table
1. Impedance :135~165Ω
2. Capacity : lower than 30 pF/m
3. Loop resistance : lower than 110Ω/Km
4. Wire diameter : larger than 0.65mm
5. Core cross-section : larger than 0.34mm

2.3. Status Indicator
PROFI-2510 PROFI-2541(SC)
It provides three status indicator, In PROFI-2510, they are PWR LED
(red),DP1 LED(green) and DP2 LED (green). In PROFI-2541(SC), they are
PWR LED (red), TxD LED(green) and RxD LED (green). When the power is supplied to module, PWR LED will turn on; Transmitting/receiving one data to/from fiber cable will flash the DP1/DP2/TxD/RxD LED once. The
DP1/DP2/TxD/RxD LED may always be turned on if there are a lot of datas transmitted on fiber cable.
