6 EC Directives

The MULTIPLE I/O TERMINAL conforms to EMC and Low Voltage Directives as follows:

EMC

Directives

OMRON devices that comply with EC Directives also conform to the related EMC standards so that they can be more easily built into other devices or the overall machine. The actual products have been checked for conformity to EMC standards (see the following note). Whether the products conform to the standards in the system used by the customer, however,must be checked by the customer.

EMC-related performance of the OMRON devices that comply with EC Directives will vary depending on the configuration, wiring, and other conditions of the equipment or control panel on which the OMRON devices are installed. The customer must, therefore, perform the final check to confirm that devices and the overall machine conform to EMC standards.

Low Voltage

Always ensure that devices (Relay Units) operating at voltages of 50 to 1,000 VAC and 75 to 1,500 VDC meet the required safety standards (IEC255).

The MULTIPLE I/O TERMINALS that comply with EC Directives must be installed as follows:

Directive

6EC Directives

1, 2, 3... 1. MULTIPLE I/O TERMINALS are designed for installation inside control

panels. All MULTIPLE I/O TERMINALS must be installed within control panels.

2. Used reinforced insulation or double insulation for the DC power supplies used for the communications power supply, internal circuit power supply, and the I/O power supplies.

3. MULTIPLE I/O TERMINAL products that meet EC Directives also meet the Common Emission Standard (EN50081-2). However, radiated emission (at 10 m) will vary with the overall configuration of the control panel, other devices connected to the control panel, and other conditions. You must therefore confirm that EC Directives are satisfied for the overall machine or device.

Uniform bus access protocol

PROFIBUS ( standard for a wide range of applications in manufacturing, process and building automation. Vendor independence and openness are guaranteed by the PROFIBUS standard EN50170-2. With PROFIBUS, devices of different manufacturers can communicate without special interface adjustments.

The PROFIBUS family consists of three compatible versions:

PROFIBUS-DP

stands forDecentralisedPeriphery. It is optimised for high speed and

low-cost interfacing, especially designed for communication between automation control systems and distributed I/O at the device level.

PROFIBUS-PA

stands forProcessAutomation. It permits sensors and actuators to be

connected on one common bus line even in intrinsically-safe areas. It permits data communication and power supply over the bus using 2-wire technology according to the international standard IEC 1158-2.

PROFIBUS-FMS

stands forFieldbusMessageSpecification. This version is the

FMS

general-purpose solution for communication tasks at a higher level. Powerful services open up a wide range of applications and provide great flexibility. It can also be used for extensive and complex communications tasks.

PROFIBUS-DP and PROFIBUS-FMS use the same transmission technology and a uniform bus access protocol. Thus, both versions can be operated simultaneously on the same cable. However, FMS field devices cannot be controlled by DP masters or vice versa.

1-2 Protocol architecture

NOTDEFINE

1-2SectionProtocol architecture

OSI

Layer 1, 2 and user interface

The PROFIBUS-DP protocol architecture is oriented on the Open System Interconnection (OSI) reference model in accordance with the international standard ISO 7498.

DP-Profiles

DP-Extensions User Interface Layer DP Basic Functions (7) Application Layer (6) Presentation Layer (5) Session Layer (4) Transport Layer (3) Network Layer (2) Data Link Layer Fieldbus Data Link (FDL) (1) Physical Layer RS-485 / Fibre Optics

OSI layer model of PROFIBUS-DP

PROFIBUS-DP uses layers 1 and 2, and the user interface. Layers 3 to 7 are not defined.

Layer 1 (physical layer) defines the physical transmission characteristics.

Layer 2 (data link layer) defines the bus access protocol.

This streamlined architecture ensures fast and efficient data transmission. The application functions which are available to the user, as well as the system and device behaviour of the various PROFIBUS-DP device types, are specified in the user interface.

NOT DEFINED

Transmission medium

Easy installation

Cable length

RS-485 transmission technology or fibre optics are defined as transmission medium. RS-485 transmission is the most frequently used transmission technology. Its application area includes all areas in which high transmission speed and simple inexpensive installation are required. Twisted pair shielded copper cable with one conductor pair is used.

The RS-485 transmission technology is very easy to handle. Installation of the twisted pair cable does not require expert knowledge. The bus structure permits addition and removal of stations or step-by-step commissioning of the system without influencing the other stations. Later expansions have no effect on stations which are already in operation.

Various transmission speeds between 9.6 kbit/s and 12 Mbit/s can be selected. One unique transmission speed is selected for all devices on the bus when the system is commissioned.

The maximum cable length depends on the transmission speed (see section 2-3-1). The length can be increased by the use of repeaters. The use of more than 3 repeaters in series is not recommended.

1-3 Device types

1-3SectionDevice types

PROFIBUS-DP distinguishes between master devices and slave devices.

Master devices

DPM1, DPM2

Slave devices

Master devices control the data communication on the bus. PROFIBUS-DP allows more then one master in the network. A master can send messages without an external request, as long as it holds the bus access right (the token). Masters are also called active stations in the PROFIBUS-DP standard.

There are two types of master devices: DP master class 1 (DPM1) and DP master class 2 (DPM2).

A DPM1 is a central controller, which exchanges information with the decentralised stations (i.e. DP slaves) within a specified message cycle.

DPM2 devices are programmers, configuration devices or operator panels. They are used during commissioning for configuration of the DP system or for operation and monitoring purposes.

Slave devices are peripheral devices. Typical slave devices include input/output devices, valves, drives and measuring transmitters. They do not have bus access rights and they can only acknowledge received messages or send messages to the master when requested to do so. Slaves are also called passive stations.

The PRT1-COM is a modular slave device.

1-4 PROFIBUS-DP characteristics

1-4-1 Bus Access Protocol

1-4SectionPROFIBUS-DP characteristics

Layer 2

Medium Access Control

T oken passing

Polling procedure

The bus access protocol is defined by layer 2. This protocol also includes data security and the handling of the transmission protocols and messages.

The Medium Access Control (MAC) specifies the procedures, which determine when a station is permitted to transmit data. A token passing procedure is used to handle the bus access between master devices, and a polling procedure is used to handle the communication between a master device and its assigned slave device(s).

The token passing procedure guarantees that the bus access right (the token) is assigned to each master within a precisely defined time frame. The token message, a special message for passing access rights from one master to the next master, must be passed around the logical token ring - once to each master

- within a specified target rotation time.

The polling or master-slave procedure permits the master, which currently owns the token, to access its assigned slaves. The picture below shows a possible configuration.

Token passing and Slave polling mechanisms

The configuration shows three active stations (masters) and six passive stations (slaves).

The three masters form a logical token ring. When an active station receives the token message, it can perform its master role for a certain period of time. During this time it can communicate with all assigned slave stations in a master-slave communication relationship. In addition a DPM2 master can take the initiative to communicate with DPM1 master stations in a master-master communication relationship.

Multi-peer communication

In addition to logical peer-to-peer data transmission, PROFIBUS-DP provides multi-peer communication (broadcast and multicast).

Broadcast communication: an active station sends an unacknowledged

Multicast communication: an active station sends an unacknowledged

message to all other stations (master and slaves).

message to a predetermined group of stations (master and slaves).

1-4-2 Data throughput

1-4SectionPROFIBUS-DP characteristics

Transmission time

At 12 Mbit/s, PROFIBUS-DP requires approximately 1 ms for the transmission of 512 bits of input data and 512 bits of output data distributed over 32 stations.

The figure below shows the typical PROFIBUS-DP transmission time depending on the number of stations and the transmission speed. The data throughput will decrease when more than one master is used.

Bus cycle time vs number of slaves

Conditions: Each slave has 2 bytes of input data and 2 bytes of output data.

1-4-3 Diagnostics functions

Extensive diagnostics

Device related diagnostics

Module related diagnostics

Channel related diagnostics

The extensive diagnostic functions of PROFIBUS-DP enable fast location of faults. The diagnostic messages are transmitted over the bus and collected at the master. These messages are divided into three levels:

• Device related diagnostics

This diagnostic level concerns the general operational status of the whole device (e.g. overtemperature or low voltage).

• Module related diagnostics

This diagnostic level indicates that a fault is present in a specific I/O range (e.g. an 8-bit output module) of a station.

• Channel related diagnostics

This diagnostic level indicates an error at an individual input or output (e.g. short circuit on output 5).

Page 21

1-4-4 Protection mechanisms

1-4SectionDevice types

Time monitoring

At the master

At the slave

PROFIBUS-DP provides effective protection functions against parameterisation errors or failure of the transmission equipment. Time monitoring is provided at the DP master and at the DP slaves. The monitoring interval is specified during the configuration.

• Protection mechanism at the master.

The DPM1 master monitors data transmission of its active slaves with the Data_Control_Timer. A separate control timer is used for each slave. This timer expires, when correct data transmission does not occur within the monitoring interval.

If the master’s Auto_Clear Mode has been enabled, the DPM1 will exit its Operate state, switches the outputs of all assigned slaves to fail-safe status and changes to its Clear status (see also section 1-4-5).

• Protection mechanisms at the slave.

The slave uses the watchdog control to detect failures of the master or the transmission line. If no data communication with the master occurs within the watchdog control interval, the slave automatically switches its outputs to the fail-safe status. This mechanism can be enabled or disabled for each individual slave.

Also, access protection is available for the inputs and outputs of the DP slaves operating in multi-master systems. This ensures that direct access can only be performed by the authorised master. For all other masters, the slaves offer an image of their inputs and outputs, which can be read from any master, even without access rights.

1-4-5 Network states

Off-line

Stop

Clear

Operate

Auto_clear

PROFIBUS-DP distinguishes four different network states.

• Off-line

Communication between all PROFIBUS-DP devices on a network is stopped.

• Stop

Communication between DPM1 and DP slaves is stopped. Only communication between DPM1 and DPM2 is possible.

• Clear

DPM1 master attempts to set parameters, check the configuration, and subsequently perform data exchange with its associated DP-slaves. The data exchange comprises reading the inputs of the DP-slaves and writing zeros to the outputs of the DP-slaves.

• Operate

DPM1 master exchanges data with its assigned slaves, inputs are read and outputs are written. Beside this, the DPM1 cyclically sends its local status to all assigned DP slaves (using a multicast message) at a configurable time interval.

When an error occurs during the data exchange phase of the DPM1, the ’Auto_clear’ configuration parameter determines the subsequent actions. If this parameter is set to false, the DPM1 remains in the Operate state. If set to true, the DPM1 switches the outputs of all assigned DP slaves to the fail-safe state and the network state changes to the Clear state.

DDB-file, GSD-file

General section

DP-master section

DP-slave section

Configurator

To achieve simple plug-and-play configuration of the PROFIBUS-DP network, the characteristic features of a device are specified in a file. This file is called a DDB-file (Device Data Base file) or a GSD-file (Gerätestammdaten file). The GSD files are prepared individually by the vendor for each type of device, according a fixed format. Some parameters are mandatory, some have a default value and some are optional.

The device data base file is divided into three parts:

• General specifications

This section contains vendor and device names, hardware and software release versions, station type and identification number, protocol specification and the baud rates supported.

• DP master-related specifications

This section contains all parameters, which only apply to DP master devices (e.g. maximum memory size for master parameter set, maximum number of entries in the list of active stations or the maximum number of slaves the master can handle).

• DP slave-related specifications

This section contains all specifications related to slaves (e.g. minimum time between two slave poll cycles, specification of the inputs and outputs and consistency of the I/O data).

The device data base file of each device is loaded in the configurator and downloaded to the master device.

Refer to the Operation Manual of the PROFIBUS-DP Master Unit (W349) for usage of the GSD file in the master’s configuration software.

1-6 Profiles

1-6SectionProfiles

Exchanging devices

To enable the exchange of devices from different vendors, the user data has to have the same format. The PROFIBUS-DP protocol does not define the format of user data, it is only responsible for the transmission of this data.

The format of user data may be defined in so called profiles. Profiles can reduce engineering costs since the meaning of application-related parameters is specified precisely. Profiles have been defined for specific areas like drive technology, encoders, and for sensors / actuators.

– This setting should always be changed to appropriate value. – Station addresses 126 and 127 are invalid and should not be used.

-- Do not use station address 0 in combination with the C200HW-PRM21 PROFIBUS-DP Master.

Data exchange method

Double byte transfer method

1. Asynchronous mode: The MULTIPLE I/O Bus transmit/receive cycles are independent of the

messages being transmitted/received at the PROFIBUS-DP interface.

2. Synchronous mode: A MULTIPLE I/O Bus transmit/receive cycle will only be initiated if new data

has been received at the PROFIBUS-DP interface.

More information can be found in: section 8-1-4.

Synchronous mode has no meaning when only input MULTIPLE I/O Units are

Note

attached. In this case the switch setting is ignored and asynchronous mode is used.

The INTEL switch is used for selection of the little-endian/big-endian mode, to define the transfer method for double-byte data transfer between PROFIBUS-DP and MULTIPLE I/O Bus.

This allows for adjustment of the data format if required by the PROFIBUS-DP master.

1. Big-endian mode (Often referred to as Motorola mode):

The first byte transmitted over PROFIBUS-DP is the most-significant byte whereas the second byte is the least-significant byte.

Mount the Unit on DIN 35-mm rail using the DIN Track Mounting Hook.

The I/O Unit Bus connectors on the MULTIPLE I/O Units must be connected with the appropriate cables to provide I/O Unit interface and allow power to be supplied to the I/O Units.

An End connector cable must be connected to the right-side connector of the last I/O Unit (terminator).

Page 30

2-2SectionCommunication Unit PRT1-COM

One I/O Unit connecting cable (cable length 40 mm) is included with each I/O Unit. One End connector is supplied with the Communication Unit. An I/O Unit connecting cable with a cable length of 1 m (GCN1-100) is sold separately.

Connect the I/O Unit connecting cable to the right connector on the Communication Unit and to the left connector of the I/O Unit as shown in the following figure.

Bus structure

Cable type

Cable

All PROFIBUS-DP devices are connected in a line structure. Each RS485 bus segment may contain up to 32 stations (masters, slaves, repeaters). When more than 32 stations are required, repeaters must be used to link the individual bus segments. The bus must be terminated at the beginning and at the end of each segment.

The standard EN50170-2 specifies the use of shielded twisted pair cables with the following parameters (PROFIBUS-DP line type A):

PROFIBUS-DP Cable parameters

Parameter Value

Impedance 135 to 165 Ω (3~20 MHz)

Capacitance per unit length <30pF/m Loop resistance <110Ω/km

Core diameter >0.64mm

Core cross section >0.34mm2(22 AWG)

The PROFIBUS-DP User Group recommends the following colour coding for the data signal lines:

A-line - green

B-line - red

Maximum length

Stub lines

Fieldbus connector

The maximum length of the cable depends on the transmission speed. The cable lengths specified in the table below are based on the above cable specifications.

Cable length vs. Baud rate

Baud rate (kbit/s) length/segment (m)

9.6, 19.2, 45.45, 93.75 1200

187.5 1000

500 400

1500 200

3000, 6000, 12000 100

Stub lines should be avoided for data transmission speeds of more than 500 kbit/s. Plug connectors available on the market permit the incoming data cable and the outgoing data cable to be connected directly in the plug connector. This means that stub lines do not have to be used, and the bus plug connector can be connected and disconnected at all times without interrupting data communication with the other stations.

The connector plug to connect to the PRT1-COM is a 9-pin male sub-D connector, preferably with a metal case, conducting screws and a solder lip for connecting the shield of the cable. The cable should at least be connected to pin 3 (B-line) and pin 8 (A-line) of the connector.

Page 32

At baud rates over 1.5 Mbit/s, always use special PROFIBUS-DP connectors with built-in series inductances, to ensure that cable reflections caused by the capacitive load of each unit are minimised.

Connectors with built-in inductors and termination resistors, as shown here, are available from various manufacturers

RTS

VP, DGND

Shielding

The signal RTS (TTL signal relative to DGND) is meant for the direction control of repeaters in case repeaters without self control capability are used.

The signals VP and DGND are meant to power an externally mounted bus terminator (see figure). The powering of the 220 Ω termination resistor ensures a defined idle state potential on the data lines. To ensure proper functioning up to the highest baud rate, the bus cable has to be terminated at both ends of the cable.

PROFIBUS-DP Termination

To ensure electro-magnetic compatibility (EMC), the shield of the cable should be connected to the metal case and to pin 1 of the connector.

If the Unit is installed within a control cabinet, the cable shield of the incoming bus cable should be electrically connected to a grounding rail as close as possible to the cable lead-through using a shield grounding clamp or similar.The cable shield should continue within the cabinet to the fieldbus device and be connected there in accordance with the manufacturers instructions.

Ensure that the PLC and the control cabinet in which the device is mounted have the same ground potential by providing a large-area metallic contact to ground (use e.g. galvanised steel to ensure a good connection). Grounding rails should not be attached to painted surfaces.

Page 33

2-3SectionSetting up a PROFIBUS-DP network

If the above measures are observed, electro-magnetic interference is diverted through the cable’s shield.

• Example of an equipment report

in the PROFIBUS-DP guideline ”Installation Guideline for PROFIBUS-DP/FMS” (PNO Order No- 2.112), which is available at every regional PROFIBUS-DP User Organisation.

Repeaters

The maximum communication distance can be increased by the use of repeaters. The repeater must be included in the count of the number of stations per segment. Even though repeaters do not have a node address, they represent an electrical load on the bus segment like any master or slave station.

If a repeater is located at the end of a bus segment, it should provide bus termination as well.

It is recommended to limit the number of repeaters in series between any two stations in the system to a maximum of three units, as shown in the following example (3 repeaters are encountered in communication between section 6 and sections 1, 2 and 4).

Example of a PROFIBUS system using repeaters

2-3-2 Configuring PROFIBUS-DP system

After making the physical connections of the network, the PROFIBUS-DP system needs to be configured. For each master and its assigned slaves, a configuration has to be defined using a dedicated configuration program.

Page 34

2-3SectionSetting up a PROFIBUS-DP network

Configurator

C200HW-PRM21

GSD file

Example

Limits defined by GSD file

List of available I/O Units type

The configurator provides the master with information about:

• The slaves that are connected to the master.

• The assignment of slaves to groups for broadcast / multicast messages.

• The mapping of the slaves into the memory of the master.

• The bus parameters (e.g. baud rate, target rotation time etc.).

For more details about the configurator for the C200HW-PRM21 Master Unit, refer to OMRON Catalog No. W349-E1.

To configure a master Unit to communicate with the PRT1-COM together with the MULTIPLE I/O Units, the PRT1-COM device database file OC_047D.GSD is required. Based on the contents of this file, the configuration program for the master Unit will allow the user to select the MULTIPLE I/O Units.

The example below shows a configuration screen of the PRT1-COM. Here the PRT1-COM is configured as a slave with 5 MULTIPE I/O Units.

The terms input and output are to be interpreted as seen from the PROFIBUS-DP master unit.

must

The list of selected I/O Units should exactly match the attached MULTIPLE I/O Units. The first I/O Unit (in the example specified in the second row: GT1-ID16-1) should be placed next to the PRT1-COM. The consecutive selected I/O Units should be physically placed in this order from left to right. The last I/O Unit (example: GT1-CT01) should be placed at the right end. This I/O Unit requires the End connector.

Upon startup of the PROFIBUS-DP communication, the master will send a Chk_Cfg message so that PRT1-COM can verify that the master’s expected I/O configuration for the PRT1-COM is correct.

On power-up PRT1-COM determines an I/O table of the attached I/O Units. The I/O table is compared with the I/O configuration by:

– Amount of I/O bytes per I/O Unit

Page 35

2-3SectionSetting up a PROFIBUS-DP network

– Consistency per I/O Unit

– Order of I/O Units (physical position)

If it does not match completely, PRT1-COM will give a negative response to the PROFIBUS-DP master and will not exchange I/O data.

Re-use the configurator program again to match the selected I/O Units with the physically attached I/O Units in case the configuration is changed.

3-1 MULTIPLE I/O TERMINAL

3-1-1 Overview

A MULTIPLE I/O TERMINAL is a modular PROFIBUS-DP Slave that consists of a Communication Unit providing an interface to one or more I/O Units. The I/O Unit interface supports up to 8 I/O Units and a total of up to 128 byte input + 128 byte output. I/O Units are connected using simple connections via I/O Unit Connecting Cables. Allocation and address settings on the I/O Unit interface are not required, enabling simple, flexible distributed I/O control.

Many Types of I/O Unit

Total number of input bytes: 128. Total number of output bytes: 128

The Communication Unit and the I/O Units are separate, and the Communication Unit and the I/O Units are connected through an I/O Unit interface. I/O can be expanded simply by connecting additional I/O Units to the I/O Unit interface.

Status information about the I/O Unit interface is transmitted as input data to the PROFIBUS-DP Master Unit (two words).

The following I/O Units are available.

• 16- or 32-point Transistor Input Units (terminal block, connector, 25-pin D-sub

connector, or high-density connector)

• 16- or 32-point Transistor Output Units (terminal block, connector, 25-pin

D-sub connector, or high-density connector)

• 8-point/16-point Relay Output Unit

• 4- or 8-point Analog Input Unit (terminal block or connector)

• 4-point Analog Output Unit (terminal block or connector)

• 1-point Pulse Input Unit (high-speed counter)

An I/O-intensive System Can be Built at Low Cost

Compared with fixed I/O Terminals, a high cost-performance ratio can be achieved if I/O Units are used.

I/O Unit Interface Addresses

Calculation Example

When three GT1-ID32ML Input Units and three GT1-OD16 Output Units are used, the total current consumption is calculated as follows:

(GT1-ID32ML current consumption) x 3 Units + (GT1-OD16 current consumption) x 3 Units = 55 mA x 3 + 35 mA x 3 = 270 mA ≤ 300 mA

The addresses of the I/O Units on the I/O Unit interface are automatically set when the Communication Unit is started. The addresses are from 0 to 7 in ascending order from the I/O Units closest to the Communication Unit.

Checking the I/O Unit Interface Status

The following two methods are used to check the I/O Unit interface status:

• Checking the Communication Unit and I/O Unit indicators

• Checking the status of the Communication Unit

Initialization

When the Communication Unit is started, it automatically recognizes the configuration of the I/O Units and registers this status as the normal configuration (in RAM memory). At the same time, addresses 0 to 7 are allocated to the I/O Units in ascending order from the I/O Unit closest to the Communication Unit. This I/O table is compared with the PROFIBUS-DP Chk-cfg message. These processes are performed each time the power is turned ON.

Error Processing

3-2-3 Allocating I/O

Even if an error occurs in the I/O Unit interface after initialization is completed, PROFIBUS-DP communications will continue normally. Therefore, an error processing program section must be included in the CPU Unit to check the status of the Communication Unit for errors that have occurred and to identify the error type and location.

This section explains how words for a MULTIPLE I/O TERMINAL are allocated in the output area and input area of the Master.

3-2-4 I/O Unit Interface Status

The following I/O Unit interface status is maintained in the CPU Unit.

• I/O Unit connection information (I/O Unit interface status)

• Registered I/O Unit addresses

• Error I/O Unit addresses

As shown in the following diagram, the status consists of two words. The first two words of the Communication Unit allocation input area in the CPU Unit are allocated for this status. Include a program section in the CPU Unit to check this status and perform error processing.

3-2-5 I/O Configuration Changes

The I/O Unit interface automatically recognizes the I/O Unit configuration each time the Communication Unit is started up.

Note

1. If the I/O Unit configuration is changed while the Communication Unit is turned ON, a configuration error will occur. Do not change the I/O Unit configuration while power is being supplied to the Communication Unit.

2. If a configuration error occurs on the I/O Unit interface, I/O refreshing of all I/O Units will stop. Even if a configuration error occurs, communications with the PROFIBUS-DP Network will continue, using the initial I/O Unit configuration. An error processing program section must therefore be included in the CPU Unit to regularly check whether or not a configuration error has occurred (status bit 1) and to process abnormal I/O Unit addresses.

If the I/O configuration is changed, then the PROFIBUS-DP System should be reconfigured, see 2-3-2.

Be sure to separate the communications power supply, the internal power supply for the Communication Unit and the CPU Bus Unit, and the power supplies for the I/O Units. If the same power supply is used, malfunction due to noise may occur.

The above formula applies when a voltage of 24-VDC is supplied to the Communication Unit internal power supply terminals. If the supplied voltage becomes lower, the current consumption will increase. Select a device for the power supply that will allow a degree of variation. When selecting a power supply, take inrush current into consideration. The following OMRON products are recommended for the 24-VDC power supply:

S82K-05024: 100 to 120/200 to 240 VAC, 50 W S82K-10024: 100 to 120/200 to 240 VAC, 100 W S82J-5524: 100 to 120 VAC, 50 W

S82J-5024: 100 to 120 VAC, 100 W For details of the I/O Unit interface current consumption for the Units, refer to page 30, I/O Interface Current Consumption.

5-1-2 Present Count Value Reading

If the following bits in the output area for the Counter Unit have been set to ON, the set values or the present count value (count value) will always be read to words m and m+1 in the input area.

To read set value 1: Output area word n+2, bit 04 To read set value 2: Output area word n+2, bit 05 To read count value: Output area word n+2, bit 06

The simplest example of a program to commence count operation and obtain the count value is given in the following. For details refer to 7-3 Counter Unit.

5-1SectionExamples of Counter Unit Operation

Note

1. To execute counting, it is necessary to set the count mode. If the count mode is changed during count operation, however, the count value will be cleared to 0.

2. Setting and reading will not be executed if a bit with a higher priority is ON. As shown in the following example, therefore, it is recommended that word n+2 be used with the MOV instruction.

5-1-4 Count Restart Operation after Error Clearance

If power supply from the I/O Unit interface to the Counter Unit is interrupted, the Counter Unit will stop count operation. It will be necessary to restart the count operation. When the Counter Unit is restarted, all settings, such as the setting values, the present value, and the count mode will be cleared. These settings must be reset. By adding the following program to the program described in the previous section, 5-1-3 Counter Setting and Execution, the settings will be reset automatically when the Counter Unit is restarted, and it will be possible to resume count operations. An example of the program used, along with an explanation of that program appears below. For details about the status area of the Master Unit, refer to PROFIBUS-DP Operation Manual (W349).
