1. INTRODUCTION
1.1 General Description
This instruction manual describes the communication command of the RM10C Recorder. Please refer to the
instruction manual (HXPRM10mnC0001E, HXPRM10mnC0002E) for the transmission of the measurement
data, a setup of communication and wiring.
1.2 Difference in RS-485, RS-232C
There is no difference between RS-232C and RS-485 about the communication command in this Recorder.
But, wiring and signal level are different.
1.3 Original Protocol - Basic item about the command
The communication command consists of a command distinction code, a parameter, delimiter(comma),
and terminator. The format of the command is as follows.
（Example）ＳＲ０２ ＶＯＬＴ,２００ｍＶ,０，２００００ （ｔｅｒｍｉｎａｔｏｒ）
Command distinction code:
This code is defined by two characters the capital letter. (Exp. SR)
If the command needs a channel number, a channel number is described behind the
distinction code.
Parameter: Each parameter is divided with comma.
All the setting value is shown with the integer. (The plus sign can be omitted.)
The space character in the input parameter is ignored. The other side, the space
character in the unit code, the comment printout code and the tag printout code isn't
ignored. The parameter can be omitted unless the parameter is varied. But, a comma(,)
can't be omitted. Comma which is in front of the terminator can be omitted.
（Example）ＳＲ０２，ＶＯＬＴ，，，（ＣＲ）（ＬＦ）
The date parameter, the time parameter and the channel number parameter have fixed
length. When that parameter length is different, these data induce errors.
（１）Date ＹＹ／ＭＭ／ＤＤ （８ characters）
（２）Time ＨＨ：ＭＭ：ＳＳ （８ characters）
（３）Channel Number：CHXX （２characters）

1.4 Basic item about the Modbus RTU protocol
Modbus protocol is a Modicon Inc. (AEG Schneider Automation International SAS) is a communication
protocol that was developed for the PLC, are listed in the protocol specification (PI-MBUS-300 Rev.J).
Please refer to the same specification for the specification of the Modbus protocol.
In this manual, we describe the function code and data content of mainly Modbus protocol that can be used
in the present equipment.

CH: Specify the channel number to set.
Mode: The input mode is set up.
PrN: The number of PrNvaries depend on the contents of Mode.
（１） Setting of the record skip.
The record of the channel, which specified with CH is stopped.
(The pen of pen type recorder is fixed on the zero point.)
ＣＨ：Setting Channel 01～０６(The pen type is 01～02.).
Ｍｏｄｅ：SKIP
Example）SR05,SKIP(CR)(LF)
The 5th channel doesn't record.

3. ORIGINAL PROTOCOL - DATA TRANSMISSION
3.1 Getting the Set Value
When the recorder receives "（ＴＳ１）＋（ＥＳＣ Ｔ）＋（ＬＦ）", the recorder sends the setting value continuously
according to the following table 3.1.
The output formats of each command are as same as that of format when it set up.

4. ORIGINAL PROTOCOL - NOTES OF COMMUNICATION
4.1 Half-Duplex Transmission
The recorder side is the half-duplex transmission. The recorder cannot receive the data while sending
the data. When the host computer sends the next data, all the receiving data must be completed.
4.2 Multiple access
Don't open another recorder when one recorder is opened on the same line.
4.3 Continuation of Opening the Link
Don't take interval for a long time, after sending the open command.
The syntax error may occur when not sending data some time.
Be sure to send the close command "ＥＳＣ Ｃ" when you do not use the communication.
If the syntax error occurs, send the status output command "ＥＳＣ Ｓ" to reset the error.
(※The close command cannot reset the syntax error.)
4.4 Outputting the Status
When the open-link recorder has a data error on its link, the recorder saves the error in the internal status
area as a communication error. The "ＥＳＣ Ｓ" command can reads this status.
Issuing this command clears the on-going error. Refer to chapter 8.5 in the instruction manual.
(HXPRM10mnC0001E, HXPRM10mnC0002E)
Be sure to reset the error when data set to recorder. When no error reset, you may not be able to judge
command, which the error specify.
