Parameters of Commands and Responses
This section describes the parameters used with various commands and responses.
Coriolis Digital Flow Sensor FD-S Series
■ Communication commands
There are two types of communication commands: read commands and write commands.
■ 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 of ID number 00 = 00, sensor amplifier of ID number 02 = 02
Communication
command
Attribute Description
SR
Read
Reads the data for the specified data number from the sensor amplifier with the
specified ID number.
M0
Reads all of the instantaneous flow rate (current value) data that DL-RS1A
periodically retrieves from all sensor amplifiers.
MS
Reads the control output state and instantaneous flow rate (current value) data
that DL-RS1A periodically retrieves from all sensor amplifiers.
DR
Reads the control output state and instantaneous flow rate (current value) data
that DL-RS1A periodically retrieves from all sensor amplifiers when a DRQ input
is received.
SW
Write
Writes setting data for the specified data number into the sensor amplifier with
the specified ID number.
AW Writes setting data for the specified data number into all sensor amplifiers.
Parameters of Commands and Responses
■ Data numbers
Specify the data number using three digits (ASCII characters).
● Read-only data
The following table lists the types of data that can only be read from FD-S Series sensor amplifiers.
Writing read-only data results in a communication error (error number: 22).
*1 In the Data format column, "*" signifies a number from "0 to 9".
*2 R: Indicates that the data type can only be read from the sensor amplifiers.
*3 Regardless of the display mode setting specified on the sensor amplifier, this is the data during
the “rESo” mode.
*4 Regardless of the integration display unit specified on the sensor amplifiers, the data is read
with the minimum display unit.
When the integrated flow quantity exceeds the indicated maximum value, the maximum value is
returned as the data.
