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 PrN varies 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.
（２） Setting of the Voltage, the Current, the Thermocouple or the ＲＴＤ input range.

Ｐｒ２：Left end(Zero Input Value)
Ｐｒ３：Right end(Span Input Value)
― ―
Example）SR05,02,DELT,0,3000(CR)(LF)
The output of the 5th channel shows a difference between the input of the 5th channel and
the 2nd channel (CH5-CH2). In this case, the input range of 5th channel becomes the
same as 2nd channel.
