1 EZ204-DP The EZ204-DP communication module was developed for automation tasks using the PROFIBUS-DP fieldbus. The EZ204-DP is a gateway and can only be used in conjunction with the EZ700, EZ800 or EZD basic units. The EZ control relay or EZD device with a PROFIBUS-DP gateway always works as a slave station on the network. MN05013001E For more information visit: www.EatonElectrical.

PAGE 23
Connecting PROFIBUS-DP Use a 9-pole SUB-D plug to connect the PROFIBUS-DP interface to the PROFIBUS-DP fieldbus. For this use the special PROFIBUS-DP plug and the special PROFIBUS-DP cable available from the Eaton range of accessories. The type of cable used determines the permissible maximum bus length and the transfer rate.
PAGE 24
Installation Bus terminating resistors The first and last station in a bus segment must be connected to the bus with the bus terminating resistor switched on. The bus terminating resistor is switched externally. This external switch function can either be implemented as a separate bus terminating resistor or with a special Sub-D plug with an integrated bus termination. Eaton's PROFIBUS-DP data plug enables both bus terminating resistors to be switched on and off.

Electrical isolation M4 EZB4-102-KS1 EZB4-102-KS1 Electrical isolation The following electrical isolation should be provided for the interfaces of the EZ204-DP: a b + – c Figure 6: Potential isolation between the power supply and outputs Safe isolation of EZ-LINK 240 V AC Simple isolation of PROFIBUS-DP 24 V DC supply voltage MN05013001E For more information visit: www.EatonElectrical.
PAGE 26
Installation Transfer rates – automatic baud rate detection The EZ204-DP module automatically detects the baud rate used in the communication network after it is switched on. However, this requires that at least one station sends valid telegrams in the network. The EZ204-DP module detects the transfer rate automatically. The following transfer rates are supported: • 9.6 Kbit/s to 12000 Kbit/s Maximum distances/bus cable lengths Two types of bus cable are specified in IEC 61158.

3 Device Operation XBefore you switch on the device, verify that it is properly connected to the power supply, to the bus connector and to the basic unit. XSwitch on the power supply to the basic unit and the PROFIBUS-DP expansion unit. Initial power up The Power LED of the EZ204-DP is lit. The BUS LED is off (no communication via PROFIBUS-DP). The GW message (intelligent station connected) is displayed on the basic unit. Basic unit GW display EZ700 Flashing EZ800 Flashing EZD-CP8..
PAGE 30
Device Operation Setting the PROFIBUS-DP station address Every PROFIBUS-DP station requires an unambiguous address in the PROFIBUS-DP structure. There are two ways of setting the PROFIBUS-DP addresses on the EZ204-DP: • Using the integrated display and keypad on the EZ or EZD basic unit • Using EZSoft on the PC. Address range: 001 to 126 Setting the address on the basic unit with a display Requirements: • The basic unit (EZ700, EZ800 or EZD) and the EZ204-DP expansion unit must be fed with power.

Device Operation Cycle time of EZ basic unit Communication between the basic unit and EZ204-DP via EZLINK increases the cycle time of the basic unit. In extreme cases the cycle time may increase by 40 ms. This should be taken into account for the reaction times of the basic unit. 30 For more information visit: www.EatonElectrical.

PROFIBUS certification EZ204-DP was certified as a PROFIBUS-DP device by the PROFIBUS User Organization. EZ204-DP contains the PROFIBUS VPC3+ interface. PROFIBUS certification J Irregular operation may occur under the following conditions: • When in a multimaster system Class I and Class II DP masters with parameter or configuration data access the slave at the same time (highly unlikely). • Or if other masters based on PROFIBUS layer 2 are connected.

6 Data exchange procedure Control commands for EZ700 The “Control commands 9 bytes” module allows extended data exchange of the EZ700 on the PROFIBUS-DP communication bus. This allows you to transfer services from the following areas: • Read/write image date and time (Page 45) • Read/write image data (Page 49) and • Read/write function block data (Page 72). A data exchange procedure is required in order to ensure the safe exchange of data via PROFIBUS-DP from master to slave and vice versa.
PAGE 48
Control commands for EZ700 The master initiates the data exchange of the control commands and the addressed slave responds. During communication 9 data bytes (byte 0 = toggle byte, bytes 1 to 8 information bytes) are sent via PROFIBUS. The basic telegram structure is shown in the following diagram.
PAGE 49
Data exchange procedure J In order to use input/output data and control commands simultaneously: Only after the “Control commands” data exchange has been completed, will the I/O data be refreshed. All specified commands and parameters must be transferred in hexadecimal format. The following tables show the different control commands possible. These essential control commands fall into three essential categories – real-time clock, image and function blocks.

This allows you to transfer services from the following areas: • Read/write date and time (Page 95) • Read/write image data (Page 99) and • Read/write function block data (Page 120). A data exchange procedure is required in order to ensure the safe exchange of data via PROFIBUS-DP from master to slave and vice versa.

Glossary This glossary refers to subjects relating to PROFIBUS-DP. Acknowledge Acknowledgement returned by the receiving station after having received a signal. Active metal component Conductor or conductive component that is live when in operation. Address Number, for example, for identifying a memory location, a system or a module within a network. Addressing Assignment or setting of an address such as for a module in a network.
PAGE 198
Glossary Bus terminating resistor Resistor at the beginning and end of a bus line for preventing disturbance caused by signal reflections and for adapting bus cables. Bus terminating resistors must always be the last unit at the end of a bus segment. Capacitive coupling Capacitive (electrical) coupling develops between two conductors carrying different potentials. Typical interference sources are, for example parallel signal cables, contactor relays and static discharge.
PAGE 199
EMC Abbreviation for “Electromagnetic Compatibility”. The ability of electrical equipment to function trouble-free within a particular environment without a negative effect on the environment concerned. EN Abbreviation for “European Norm” or European standard. Equipotential bonding Adaptation of the electrical level of the body of electrical equipment and auxiliary conductive bodies by means of an electrical connection. ESD Abbreviation for “Electrostatic Discharge”.
PAGE 200
Glossary I/O Abbreviation for “Input/Output”. Impedance Apparent resistance that a component or circuit of several components has for an alternating current at a particular frequency. Inactive metal parts Conductive parts that cannot be touched and which are insulated from active metal parts. They can, however, carry voltage in the event of a fault. Inductive coupling Inductive (magnetic) coupling occurs between two current carrying conductors.
PAGE 201
NAMUR Abbreviation for “Normen-Arbeitsgemeinschaft für Mess- und Regeltechnik” (Standards Work Group for Instruments and Controls). NAMUR proximity switches represent a special category of 2-wire proximity switches. They are highly resistant to interference and reliable due to their special construction, e.g. low internal resistance, few components and short design. Overhead System management time required in the system in each transmission cycle.
PAGE 202
Glossary Protective conductor A conductor required for the protection against dangerous currents, designated by the letters PE (abbreviation of “Protective Earth”). Radiated coupling Radiated coupling occurs when an electromagnetic wave makes contact with a conductor structure. The impact of the wave induces currents and voltages. Typical interference sources are, for example ignition circuits (spark plugs, commutators of electrical motors) and transmitters (e.g.
PAGE 203
Topology Geometric structure of a network or circuit arrangement. UART Abbreviation for “Universal Asynchronous Receiver/ Transmitter”. A UART is a logic circuit used for converting an asynchronous serial data sequence into a bit-parallel data sequence or vice versa. Unidirectional Working in one direction.
