DL-DN1 Overview

Overview

Before Using

The DL-DN1 opera tes as a slave unit of DeviceNet communication. Using DeviceNet communications, the sensor amplifiers and other units connected to the DL-DN1 can transmit their ON/OFF control signals and current values as communication data to a PLC or other equipment. The DL-DN1 supports DeviceNet I/O communication (polling) and explicit messaging. I/O polling enables data communi messaging allows for reading/writing sensor amplifier parameters and issuing motion commands to the sensor amplifiers.

When the DL-DN1 is set in the PGM mode and the power is turned on, the address of the DL-DN1 is the same as used when the DL-DN1was started last time. When the DL-DN1 in the factory default setting is set to the PGM mode, the node address of the DL-DN1 is 63. Do not start multiple DL-DN1 units in factory default setting in the PGM mode, as that will result in a network error because of the duplicate node addresses.

Use the following procedure to connect the DL-DN1 to the DeviceNet system.

Configuring the Data Link

This manual covers only the functions and settings of a DeviceNet master unit which are required for communication with the DL-DN1. For the functions and settings related to the communication between the DeviceNet master unit and CPU unit, refer to the manuals shipped with your master unit or CPU unit.

Configuring the Master Unit

The following configurations are required to connect the DL-DN1 to the DeviceNet master unit.

 Slave attribute settings

Configure the master unit with the communication form, I/O size, and other information about the slave units. For this purpose, the EDS file for the DL-DN1 can be imported into the configuration software of the master unit.

The EDS file can be downloaded from the KEYENCE web site: http://www.keyence.com

Connection and Configuration

 Memory allocation settings

Configure the memory areas required for exchanging data th co

mmunication. Do this using the configuration software of the master unit.

• The memory allocations must be reconfigured if the number of connected sensors is changed, because the memory area reserved in the DL-DN1 may change.

• Cautions for connecting the Keyence master unit KV-DN20 Assign the memory allocation start address either to odd-numbered addresses or to even-numbered addresses according to operating modes of the DL-DN1 (refer to page 2-10). The current value may not be read out correctly if the assignment is not proper. Assign to odd-numbered addresses: 3-output + current value (no extended) mode 5-output + current value (no extended) mode Assign to even-numbered addresses: Operating modes other than the above

Where multiple slave units are connected, the memory allocation for each slave unit is done automatically, based on the specified starting address.

The allocation information for each slave unit can be checked using DeviceNet configuration software.

 Setting the node address

Using the address setting switch, set the DeviceNet node address to be assigned to the DL-DN1.

• Default value: 63

• Setting range: 00 to 63

When setting the node address of the DL-DN1 from the DeviceNet master unit, set it in the range of 64 to 99. The DL-DN1 enters PGM mode.

 Selecting an operating mode

Select the desired operating mode of the DL-DN1 using the operating mode setting switch. The data that can be ha ndled in I/O communication varies with each operating mode.

2-10

When the DL-DN1 is set in the PGM mode and the power is turned on, the address of the DL-DN1 is the same as used when the DL-DN1was started previously. When the DL-DN1, in the factory default setting, is set to PGM mode, the node address of the DL-DN1 is 63. Do not start multiple DL-DN1 units in factory default setting in the PGM mode, as that will result in a network error because of the duplicate node addresses.

of each function assigned for external inputs (1 to 5). For details, refer to "Command Parameter List for FD-S Series" (page 3-25).

 I/O Communication

• The output signal, comparator value, and error status of sensor amplifiers can be communicated without the need of a ladder program.

• By using the IN and OUT areas as handshake signals, the master unit can execute external inputs to the sensor amplifier or change setting values.

"I/O Communication" (page 3-4)

 Explicit Messaging

The master unit can use explicit messaging commands to directly read parameter values of

sensor amplifiers. All functions that can be executed on sensor

amplifiers are available through explicit messaging.

I/O Communication

The device map varies depending on the operating mode of the DL-DN1. Select an operating mode suited for the functions of the sensor amplifiers to be used, before accessing each device. The memory in the DeviceNet master unit is linked to the buffer memory in the DLDN1 as shown below.

Communicating with the FD-S series

Selecting the DL-DN1 Operating Mode

Select the DL-DN1 operating mode to suit the functions of the sensor amplifiers to be used. The DeviceNet device configuration and the data available for I/O communication vary, depending on the selected operating mode of the DL-DN1 and the number of connected sensor a mplifiers. An appropriate operating mode should be determined by considering the memory occupied and the data that can be co

Explicit Messaging

The DeviceNet master unit can issue explicit messages to the DL-DN1 for the following purposes:

"Issuing a Motion Command to a Sensor Amplifier" (page 3-19)

"Reading settings or status" (page 3-20)

"Reading data with decimal point" (page 3-21)

"Writing settings or status" (page 3-21)

"Locking Sensor Amplifiers" (page 3-22)

Basic Formats of Explicit Messaging

Shown below is the basic format used when the DeviceNet master unit issues a command to the DL-DN1 and w unit, respectively.

The number of bytes used in the class ID, instance ID, and attribute ID may vary depending on the master unit. The format examples in this manual assume 2 bytes for class ID, 2 bytes for instance ID, and 1 byte for attribute ID. For details, refer to the instruction manual of the master device.

*1 The error content of the sensor amplifier can be checked by noting the ON/OFF

state of each bit.

OFF (0): No error; ON (1): Error More than one error may occur simultaneously. For details of each error, refer to

the FD-S Series Instruction Manual. *2 Details of output status can be checked by noting the ON/OFF state of each bit. *3 If the instantaneous flow rate is above the upper limit of display ran

ge ("FFFF" is

("- FFF" is displayed), the data will be "- 32768". If another error is displayed, the

data just before the error occurred or the error response (0EH) is displayed.

The data is for "rESo" irrespective of the display mode set on the sensor ampli-

fier. *4 If the integration flow value is above the upper limit, the upper limit value is

retained. If it is above the lower limit, the lower limit value is retained. If a sensor

amplifier error occurs, the data just before the error occurred or the error

response (0EH) is displayed.

Data is read in minimum display units irrespective of the integrated flow quantity

unit set on the sensor amplifier. *5 If the temperature is above the upper limit of display range ("FFFF" is displayed),

the data will be "32767". If it is below the lower limit of display range ("- FFF" is

displayed), the data will be "- 32768". If another error is displayed, the data just

before the error occurred or the error response (0EH) is displayed. *6 If a value 100.0 is written, a warning is not issued even when the temperature

exceeds the upper limit of temperature display range, but i

t is issued only when

the temperature falls below the lower limit setting. *7 If a value 000.0 is written, a warning is not issued even when the temperature

falls below the lower limit of temperature display range, but it is issued only when

the temperature exceeds the upper limit setting. *8 If "analog output selection" is set to "standard", rewriting "free range analog

upper limit" or "free range analog lower limit" fails. *9 Set this parameter to 0 when disabling zero cut. *10 If the "low density zero cut function" is OFF, changing the "low density zero cut

level" value does not take effect. *11 These parameters will be applied at the time of initial resetting.
