*7 If the the setting is changed between the 1st execution request and the 2nd execution request,

correction cannot be made. When making correction, do not change other settings midway. Also, the auto adjust function does not work between the 1st point execution request and the 2nd point execution request. Make sure to perform the 2nd point execution request next after the 1st point execution request.

*8 When reading data from the amplifier unit whose "1. Measurement mode" is set to "Dimension

mode", the reading range is changed to ±**.*** (-99.999 to +99.999). *9 This operates when "11. Bank switching method" is set to "Button". *10 This operates as OFF only when data 0 is written and the external input for wiring is OFF. *11 Specify the system parameter set when data number "006 (System parameter set request)" is

written. Convert the 2-digit number (ASCII characters) to a binary number and check the ON/

OFF state of each bit to specify the system parameter.

Bit Default settings

0 0: NPN output, 1: PNP output

3, 2, 1

010: -5 to +5 V 011: 1 to 5 V 100: 4 to 20 mA

Reference

When the specified data is "06":

•

"6" converted to binary number is "0110".

Bit 3, 2, 1: 1 to 5 V Bit 0: NPN output

Therefore, the setting of the amplifier to which the data is written is "NPN output" and "Analog output 1 to 5 V".

*12 When reading data from the amplifier unit whose "1. Measurement mode" is set to "Dimension

mode", the reading range is changed to **.***(00.000 to 99.999). *13 When changing the measurement mode, the communication response time T4 becomes max. 1

second for 1 second after the setting is changed. Also, the same result is yielded when the

setting is changed using the button operation of the sensor amplifier. *14 Writing onto expansion units results in a communication error (error number: 22). *15 To reflect the setting written for the data number 146 to 149 to the sensor amplifier, write 1 (user

setting) for the data number 145 or set the external input setting to "User setting" with the button

operation on the sensor amplifier.

 Relation between the data number 001 to 027 (data requesting the sensor

amplifier operation) and the data number 053 to 061 (data presenting the result

of request/execution)

When writing the data number 001 to 027 (data requesting the sensor amplifier operation), read the data number 053 to 061 (data presenting the result of request/execution) and check that the request is correctly reflected (1: Normal termination is read.) or the system parameter state presents the setting value. If the request is not correctly reflected and abnormal termination occurs, data other than 1: Normal termination may be read by reading the data number 053 to 061. Thus, the request may not be reflected to the sensor amplifier. When 0 o 1 is written for the data number 001 to 027, the previous state of the data number 053 to 061 is cleared and the condition is updated. The data number 053 to 061 keeps the result until 0 o 1 is written for the data number 001 to 027 next.

Example

Data number

• The data number 054 (Zero shift execution result) keeps the result of writing which either the data number 001 (Zero shift request) or data number 002 (Zero shift reset request) performed last.

• The data number 059 (Adjust result) keeps the result of writing which either the data number 011 (Adjust request) or data number 012 (Adjust reset request) performed last.

• The data number 060 (Tuning result) keeps the result of writing which any of the data number 016 (2-point tuning HIGH side 2nd request), data number 018 (2-point tuning LOW side 2nd request) or data number 014 (Tolerance tuning request) performed last.

The data number 053 (EEPROM writing result) keeps "0: Writing" approx. for 2 seconds after the contents written onto the nonvolatile memory (EEPROM) using the writing commands (SW, AW) are sent last. If writing starts after 2 seconds and finishes normally, 1: Normal termination results.

Example

If the writing commands (SW, AW) are continuously sent every second, 0: Writing results always. After the last writing commands (SW, AW) are sent, 0: Writing is kept for 2 seconds,

writing is performed after 2 seconds and 1: Normal termination results. However, when the initial reset is performed for the data number 005 (Initial reset request), writing starts immediately. If the all parameters can be saved on the nonvolatile memory (EEPROM) after approx. 3 seconds, 1: Normal termination results.

Communication Response Time

 T5 (Response send time from DL-RS1A)

The time required to send a response varies depending on the communication speed, data bit length, and number of bytes. For information on the communication settings, refer to page 2. The response time can be calculated using the following formula:

T5 = (number of bytes) x (data bit length + 4) / (communication speed)

z Number of bytes for different commands

SR command : (number of bytes in the read data) + 12 M0 command : {(number of bytes in the read data) + 1} u number of connected sensor amplifiers + 4 MS command : {(number of bytes in the read data) + 3} u number of connected sensor amplifiers + 4 DRQ input : {(number of bytes in the read data) + 3} u number of connected sensor amplifiers + 4 SW command : 11 AW command : 8 * For information on the number of bytes in the write data and the number of bytes in the read data,

refer to "Parameters of Commands and Responses" (page 10).

Sample calculation

Number of bytes Data length Communication speed Response time

21 8 bit 9600 bps 26 ms

114 8 bit 9600 bps 143 ms

 T6 (Sensor amplifier settings change time)

T6: 0ms

Data to which the setting changed after receiving response (after T5 elapses) is reflected can be read using the data reading command (M0, MS) or DRQ input.

Point

When writing to the following data number using the SW or AW command, the sensor amplifier is reset. The measured value after the setting is reflected can be read after T elapses. When reading using the data reading command (M0, MS) or DRQ input before T elapses, the P.V. value is read as "-99.998" (-------).
