Parameters of Commands and Responses

This section describes the parameters used with various commands and responses.

 Communication commands

There are two types of communication commands: read commands and write commands.

• For information on the data, refer to the SK-1000 Series instruction manual supplied with

the sensor amplifiers.

• If commands are sent during the period of approx. 3 seconds after the power is turned on,

the communication error (error number: 22) will occur.

 ID numbers

This parameter is used with communication commands "SR" and "SW". Specify the ID number of the

target sensor amplifier using two digits (ASCII characters).

(Example) Sensor amplifier with the ID number 00 = 00, sensor amplifier with the ID number 03 = 03

command

Attribute Description

Read

Reads the data for the specified data number from the sensor amplifier with the

specified ID number.

Reads the comparator value (P.V. value) that DL-RS1A periodically retrieves

from all sensor amplifiers.

Reads the ON/OFF state of the judgment output and alarm output, and the

comparator value (P.V. value) that DL-RS1A periodically retrieves from all

sensor amplifiers.

DRQ input

Reads the ON/OFF state of the judgment output and alarm output, and the

comparator value (P.V. value) that DL-RS1A periodically retrieves from all

sensor amplifiers when a DRQ input is received.

Write

Writes setting data for the specified data number onto the sensor amplifier with

the specified ID number.

AW Writes setting data for the specified data number onto all sensor amplifiers.

Point

Parameters of Commands and Responses

 Data numbers

Specify the data number using three digits (ASCII characters).

z Read-only data

The following table lists the types of data that can only be read from the SK-1000 Series sensor

amplifiers.

Writing read-only data results in a communication error (error number: 22).

*1 In the Data format column, "±" indicates that the value can be either "+" or "-" and "*" signifies a

number from "0 to 9".

*2 R: Indicates that the data type can only be read from the sensor amplifiers.

*3 You can read data number "033" to check the error status of the sensor amplifiers. Convert the

five digit number (ASCII characters) read from the sensor amplifiers to a binary number and

check the ON/OFF state of each bit to check the error.
