7.1 Functions as Talker
There are the following seventeen types of data output:
• Measured data output (ASCII code): TS0 + “Device Trigger (GET)” + FM0
• Measured data output (binary code): TS0 + “Device Trigger (GET)” + FM1
• Computed data output (ASCII code): TS0 + “Device Trigger (GET)” + FM2
• Computed data output (binary code): TS0 + “Device Trigger (GET)” + FM3
• Setting of data output in the operation mode: TS1 + “Device Trigger (GET)” + LF
• Unit and decimal point position data output: TS2 + “Device Trigger (GET)” + LF
• System configuration data output: TS5 + “Device Trigger (GET)” + CF
• A/D calibration data output: TS8 + “Device Trigger (GET)” + LF
• Setting of data output in the setup mode: TS9 + “Device Trigger (GET)” + LF
• Outputting of a file directory on a RAM disk: TS3 + [GET] + [MF0]
• Outputting of measured/computed data (ASCII code) on a RAM disk: TS3 + [GET] + MF1
• Outputting of the measured/computed data (binary code) on a RAM disk: TS3 + [GET] + MF2
• Outputting of channel on/off on a RAM disk: TS3 + [GET] + MF3
• Output the hourly report using the report function: TS4 + [GET] +RF0
• Output the daily report using the report function: TS4 + [GET] +RF1
• Output the monthly report using the report function: TS4 + [GET] +RF2
• Output the status of the hourly/daily/monthly report: TS4 + [GET] +RF3
Measured/computed or report data output (TS0/TS3)
After executing “GET,” be sure to output data using the FM or MF command. Execution of
“GET” alone without executing the FM or MF command does not output the data. After reading
all the data specified by the FM command, subsequent specification of the FM command without
executing “GET” enables the data within a scan to be output.
Because the MF command requests the output of data stored on the internal RAM disk, so a
differential in time occurs between the time when the data are measured and the time when [GET]
is executed.
Setting of data output (TS1, TS2, TS8 or TS9)
After transmitting the device trigger “GET ”be sure to output data using the LF command.
Execution of “GET” alone without executing the FM command does not output the data. After
reading all the data specified by the LF command, subsequent specification of another channel
using the LF command enables the data contents to be output. A/D calibration data output by the
TS8 command can be executed in the A/D calibration mode only.
Report output (TS4)
After transmitting the device trigger “GET ” be sure to read the data using the RF command.
Execution of “GET“ alone without executing the RF command does not read the data. After
reading all the specified data with the RF command, subsequent specification of another channel
using the RF command without executing “GET“ enables that data to be read.
System configuration output (TS5)
After transmitting the device trigger “GET ”be sure to output data using the CF command.
Execution of “GET” alone without executing the CF command does not output data.
Note
• When using an RS-232-C, RS-422-A or RS-485 interface, execute an ESCT command rather than a GET command.
• Do not transmit the FM, LF, CF, MF, RF command before outputting data for specified channels.
• If an FM, LF, CF, MF, RF command is received while data are being transmitted, transmission of the data is suspended
automatically.
• If the type of output data is changed using the TS command after the execution of “GET,” the changed contents are not
reflected without executing “GET” again. Execute “GET” again.
• After executing “GET,” the execution of “GET” again without outputting data using the FM, LF, CF, MF, RF command
or without completing the data output sets new data to the buffer. Be careful because old data are lost.
