Slot number and ID number assignment

When the sensor amplifiers are connected to the DL-PD1, slot numbers are assigned to each sensor amplifier. When using the acyclic communication with the DP-V1 service or diagnostic function used, the slot number is used to specify the target sensor amplifier for communication.

Also, ID numbers are assigned to the control output and external input of each sensor amplifier in the connection order of sensor amplifiers. ID numbers are used to identify the control output of the sensor amplifier assigned as cyclic communication data.

(Configuration example)

Executing Communication

Slot numbers and ID numbers are automatically assigned in the connection order for sensor amplifiers. If the number of connected sensor amplifiers or connection order is changed, the control program may have to be changed. Design the sensor amplifier configuration and control program with this taken into account beforehand.

"Operation mode of DL-PD1" (page 3-6) If the effective ID setting is changed on the GT2-100N (P), restart the GT2-100N (P). After restarting the GT2-100N (P), the DL-PD1 recognizes the specified number of units and communication with the units is possible.

Set the hardware configuration on the configuration software of PROFIBUS DP according to the physical configuration of the DL-PD1 and sensor amplifier connected to the DL-PD1. The setting procedure differs depending on the operation mode of DL-PD1.

Operation mode of DL-PD1

There are two types of operation modes for DL-PD1. The operation modes for DL-PD1 are switched on the hardware configuration using the configuration software of PROFIBUS DP.

 Monitor mode

Executing Communication

Use this mode to obtain the comparator value and status of sensor amplifiers via cyclic communication. The input size and output size for cyclic communication change depending on the number of sensor amplifiers connected. The maximum sizes for input and output are 107 bytes and 16 bytes respectively.

When using the monitor mode, assign the "DL-PD1" and each sensor amplifier to the PROFIBUS DP system on the hardware configuration.

When using the master compatible with the DP-V1, any of the modes can be used to read or write all information on the sensor amplifier via acyclic communication of DP-V1 service.

Acyclic communication (DP-V1 service)

 I/O mode

Use this mode to reduce the input/output size of cyclic communication to minimum. The input size and output size are 10 bytes each regardless of the number of sensor amplifiers connected. Using the cyclic communication, the control output of sensor amplifiers can be read and external output to sensor amplifiers can be performed.

When using the I/O mode, assign the "DL-PD1 without sensor amplifier" to the PROFIBUS DP system on the hardware configuration. Do not assign the sensor amplifier.

Using the slave diagnostic function of PROFIBUS DP, the information of error caused on the DL-PD1 or sensor amplifier can be sent to the master via PROFIBUS DP.

Slave diagnosis structure

The frame length of the DL-PD1 slave diagnosis is the maximum of 67 bytes. The slave diagnosis consists of 6-byte standard diagnosis, 4-byte Identifier-related diagnosis, 9byte module status and maximum of 48-byte Channel-related diagnosis. The frame length of the Channel-related diagnosis changes depending on the number of sensor amplifiers connected. The minimum length is 3 bytes and the length increases 3 bytes per sensor amplifier additionally connected.

Also, the diagnostic function can be set to Enable/Disable by slot at the parameter setting for DL-PD1. When the diagnostic function is set to Disable, the slot information is deleted from the diagnostic frame.

 In the monitor mode

Executing Communication

(1) The output octet value to which an external input request was assigned is linked via

cyclic communication and the external input of the sensor amplifier is turned on or off. (In the big endian format)

(2) You can check the input status of the sensor amplifier with the external input response.

• To use the TIMING input, set "Simultaneous Input Setting" of the sensor amplifier to "Individual Input".

• To use the TIMING input, set the "Timing Type" of the sensor amplifier to "External Timing Input".

After the external input is executed, the button operation of the sensor amplifiers is locked for about 10 seconds. "COM-Lock (comLoc)" is displayed for about 2 seconds during switching to the locked state or when an attempt is made to operate a locked button. When button operation is unlocked, "COM-Unlock (comUnL)" is displayed for about 2 seconds. However, the initialization screen appears when an initialization reset is executed. If an external input is repeatedly executed when the initialization screen is being displayed, the initialization screen is retained.

 In the I/O mode

(1) The output octet value to which an external input request was assigned is linked via

Reading comparator values (P.V. values) from sensor amplifiers

Comparator values (P.V. values) can be read only in the monitor mode. They cannot be read in the I/O mode.

"Operation mode of DL-PD1" (page 3-6)

 Example of reading the comparator value (P.V. value) from the sensor

amplifier

Executing Communication

This example shows how to read the comparator values (P.V. values) from the sensor amplifiers ID01, ID02, and ID03.

(1) When the comparator value of a sensor amplifier is updated, the value of the input

octet is also updated via cyclic communication. If the comparator value is correct, the parameter range is -199.9999 to +199.9999. If the comparator value is over range, under range, or invalid, the previous value is retained without updating the comparator value. To confirm whether the current value is correct, use the comparator value property.

(2) The comparator value invalid, comparator value over range, or comparator value

under range is entered. If the comparator value of a sensor amplifier is "invalid", "over", or "under", the bit corresponding to the ID number of that sensor amplifier flips to 1.

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

GT2 Series User's Manual. *2 Details of output status can be checked by noting the ON/OFF state of each bit. *3 If the judgment value is correct, the parameter range is -199.9999 to +199.9999.

When the comparator value is over range, "+999.9999" is stored.

When the comparator value is under range, "-999.9999" is stored.

When an error occurs, "+1000.0000" is stored. *4 When you use the calculation function and calculation setting is set to other than

standard difference display, a reading error occurs on the expansion unit. *5 In the calculation-only mode, a reading error occurs on the main unit. *6 This parameter can be used only when the detection mode of the sensor amplifier is peak-to-

peak hold. A reading error occurs when the mode is set to other than peak-to-peak hold.

This parameter may be used for judging the outer diameter of cylinders, in order to

read the peak and bottom values during measurement. *7 When you do not use the calculation function, a reading error occurs.

When the calculation setting is set to other than standard difference display, a

reading error occurs on the expansion unit.

series is used. *9 This parameter cannot be written to expansion units if the key lock function is used by the

main unit when simultaneous input is active. When a sensor amplifier of GT2-100* series

is used, this parameter cannot be written to units other than the main unit (ID: 01). *10 This parameter cannot be written when the key lock function is used.

Reference

*11 When a sensor amplifier of GT2-100* series is used, this parameter cannot be

written to units other than the main unit (ID: 01). *12 These parameters can be read/written to only the main unit (ID: 01) of sensor amplifiers. *13 Each parameter is specified as a combination of calculation mode and calculation

setting. The calculation mode is defined in the tens digit, while the calculation setting

is defined in the ones digit.

If calculation is not available (00 + m): Specify 0 in the tens digit, and specify the desired

number (0 - 7) in the ones digit, so that the result is between 00 (0h) and 07 (7h). The

specified calculating setting is written to the sensor amplifier, but it is invalid.

If calculation mode is available (10 + m) for torsion (5): 15 (Fh).

If calculation-only mode is available (20 + m) for mean (3): 23 (17h). *14 Available only for GT2-100 series. Not available for GT2-70 series.

This parameter can be read/written only when GT2-100* is used as a main unit (ID:

01) and cannot be read/written to units other than the main unit (ID: 01).

For details on batch setting, refer to the GT2-100 series User's Manual. *15 These parameters cannot be read/written when sensor amplifiers other than GT2-

71MC* series are used. *16 These parameters are available only when the calculation function is used.

Calculations other than for standard difference display are effective only on the main unit

(ID: 01). These parameters read the R.V. value (synchronized with the calculation

results) of the main/expansion unit(s) for the main unit to calculate the results.

For example, set the data number (HEX) to "01A3" when you read the value of the

expansion unit on which calculation result of the main unit is based.

Calculations for standard difference display are effective only on the expansion units (ID:

02 to ID: 15). These parameters read the R.V. value (synchronized with the calculation

results) of the main/expansion unit(s) for the expansion unit to calculate the results.

For example, set the data number (HEX) to "0A31" and send the command when

you read the value of the main unit (ID: 01) on which calculation result of the

expansion unit (ID: 03) is based.

Executing Communication

This read command is useful when you use the calculation function with the detection mode set to hold detection (peak hold) and when you read the R.V. value of the main/expansion unit(s) for calculation as well as the calculation results. The read command for the P.V. value can read the held values, while that for the R.V. value reads the raw value when the command is received. Therefore, the read R.V. value is not synchronized with the latest values. This read command can read the R.V. value of each sensor amplifier for calculating the held values. The read R.V. values are synchronized with the held values and eliminates the influence of communication response delay.

*17 The read character string is stored in ASCII code into the remote register.

FREEZE/SYNC/CLEAR command

The following are the DL-PD1's operations when the SYNC command or FREEZE command is notified to the DL-PD1 from PROFIBUS DP master.

 Operation when the FREEZE command is notified

The input data (e.g. sensor amplifier control output, comparator value, etc.) on the cyclic communication is fixed to the condition immediately before the FREEZE command is notified. If the FREEZE command is notified again, the condition will be updated.

The FREEZE command does not affect the output data (external input to the sensor amplifier) of the cyclic communication.

 Operation when the SYNC command is notified

The output data (external input to the sensor amplifier) on the cyclic communication is fixed to the condition immediately before the SYNC command is notified. If the SYNC command is notified again, the condition will be updated.

This is used when setting the external input to multiple sensor amplifiers with the same timing.

The SYNC command does not affect the input data (sensor amplifier control output, comparator value, etc.) of the cyclic communication.

 Operation when the CLEAR command is notified

The output data (external input to the sensor amplifier) of the cyclic communication is cleared. (0 is set.)

Communication error between Sensors

Description Solution

The number of sensor amplifiers increased during operation. Check the connection with the sensor amplifier.

Check the connection with the sensor amplifier and cycle the power.

There is connected a sensor amplifier of a model incompatible with the DL-PD1. Connect a sensor amplifier of a compatible model.

A foreign sensor amplifier (i.e., one that cannot be intermixed) is connected. Remove the foreign sensor amplifier.

Check the connection with the sensor amplifier and cycle the power.

The current limitation exceeds the allowable range. Check the allowable range of the number of the sensor amplifiers.

An error exists in the communication between sensor amplifiers. Check the connections of the sensor amplifiers, and then turn off the power and back on.

The station address was changed during operation. If it was not an intentional change, check the correct station address and set.

Refer to the GT2 series user's manual.
