1. 1. About the OMR Analog Input Modules

The OMR provides a series of analog input modules which can sense the ana log signal or to control the remote devices. The basic features of each module are shown here.

• OMR-6011/D : multi-functions high gain analog input module

• OMR-6012/D : multi-functions analog input module

• OMR-6013 : 3 channels RTD input module

• OMR-6014D:Analog (Transmitter) input module with LED display

• OMR-6017 : 8 channels analog input module

• OMR-6018 : 8 channels thermocouple input module

V The models with an extended D have the same command set and specification as without D, except the D version has a 5

1/2 LED Display.

1. 2. Overview of OMR-6011/D

What is OMR-6011/D ?

OMR-6011/D is a multi-functions analog input module with cold junction compensation (CJC). The maximum input voltage range of analog input channel is ±2.5V. The high gain feature allows very small full range of ±15mV. To measure temperature by directly connect the thermal couple is possible because of using the CJC inside and the high gain feature.

The voltage range of the ADC can be set according to different types of thermal couple. The ADC can be calibrated by programming without handy adjustment. This feature insure the best performance under different environment.

The module provides the analog signal monitor or the alarm function. The high and low bound of the alarm limit can be se t by programming. The alarm status can be sent to digital output channels if this function is ON. The supervisor of a factory can ‘see’ or ‘hear’ the alarm if the digital output channel control a real alarm device. The two digital output channels can be set for general purpose use if the alarm is disabled.

Introduction 1-1

For example, connecting relay devices to DO channels, the OMR-6011/D can be used to control the high power devices. The module provides another one digital input channel. This can be used for general purpose such as monitor digital

signal, or be used as input of the event counter.

2. Initialization & Installation

2. 1. Software Installation

1. If you have already installed “OMR Administration” then skip other steps.

2. Backup your software diskette.

3. Insert “OMR Administration” disc into CD-ROM:

4. Change drive to the path of CD-ROM. For example, your drive of CD-ROM is F:, then change the drive to F:

5. Find the setup of OMR Administration and run it.

6. Please follow the steps of setup program then you can successful to install the nudism Administration.

2. 2. Initializing a Brand New Module

Objective of Initializing a Brand New OMR

All OMR modules, except OMR -6520 and OMR -6510, in a RS-485 network must have an unique address ID. Every brand new OMR has a factory default setting as following:

• Address ID is 01.

• Baud rate is 9600 bps

• Check-sum disable

• Host Watchdog timer is disable

Therefore, to configure the brand new OMR before using is necessary to avoid conflicting address. The baud rate may also be changed according to user‘s requirements.

The initialization procedures of a brand new OMR are shown in the following sections. The procedures are applicable for initializing OMR-6011/D, OMR-6012/D, OMR-6013, OMR-6014D, OMR-6017, and OMR-6018.

Initialization & Installation 2-1

Default State

The OMR modules must be set at Default State when you want to change the default settings, including the ID address, baud rate, check-sum status etc. All OMR modules have an special pin labeled as DEFAULT*. The module will be in Default State if the Default*1 pin is shorted to ground when power ON. Under this state, the default configuration is set as following:

• Address ID is 00.

• Baud rate is 9600 bps.

• Check-sum disable.

• Watchdog timer is disable.

Therefore, the configuration of the host and the module can be easily set identically and initializing a module will be possible no matter what configuration is set under operating state.

Initialization Equipments

• Host computer with an RS-232 port.

• An installed RS-485 module (OMR-6520) with 9600 baud rate.

• The brand new OMR module

• Power supply (+10 VDC to +30 VDC) for OMR modules

• Administration utility software

Note1: Never Connect the DRFAULT* pin to Vs or power source just left it open or wired to GND.

2-2 Initialization & Installation

Initialization Procedure

3. Command Set

3. 1. Command and Response

Introduction

The OMR command is composed by numbers of characteristics, including the leading code, address ID, the variables, the optional check-sum bytes, and a carriage return to indicate the end of a command. The host computer can only command only one OMR module except those synchronized commands with wildcard address “**”. The OMR may or may not give response to the command. The host should check the response to handshake with the modules.

Document Conventions

The following syntax conventions describes the OMR commands in this manual.

(Leading Code) Leading Code is the first characteristic of the OMR

(Addr) Module’s address ID, the value is in the range of 00 (Command

Variable) [Data] Some commands need additional data.

[Checksum] Checksum in brackets indicate optional parameter,

< > Identifies a control code character, such as <CR> for

command. All OMR commands need a command leading code, such as %,$,#,@,...etc. 1- character

FF (Hex). 2- character Command codes or value of variables.

Variable length Variable length only checksum is enable then this field is required. 2-

character carriage return, its value is 0x0D.

1- character

Format of OMR Commands

(Leading Code)(Addr)(Command)[Data] [Checksum]<CR>

Command Set 3-1

When checksum is enable then [Checksum] is needed, it is 2-character. Both command and response must append the checksum characters.

How to calculate checksum value ? [Checksum] = ((LeadingCode)+(Addr)+(Command)+[Data]) MOD 0x100

Example 1: checksum is disable

User Command : $012<CR> Response : !01400600<CR>

$ : LeadingCode 01 : Address 2 : Command (Read Configuration) <CR> : Carriage return 0x0D

Example 2: checksum is enable

User Command : $012B7<CR> Response : !01400600AC<CR>

$ : LeadingCode 01 : Address 2 : Command (Read Configuration) B7 : Checksum value <CR> : Carriage return 0x0D

‘$’ = 0x24 ‘0’ = 0x30 ‘1’ = 0x31 ‘2’ = 0x32

B7 = ( 0x24 + 0x30 + 0x31 + 0x32 ) MOD 0x100

‘!’ = 0x24 ‘0’ = 0x30 ‘1’ = 0x31 ‘4’ = 0x34 ‘6’ = 0x36

AC = ( 0x24 + 0x30 + 0x31 + 0x34 + 0x30 + 0x30 + 0x36 + 0x30 + 0x30 ) MOD 0x100

Note : 1. There is no spacing between the command words and The checksum characters.

2. Every command follows a <CR> carriage return for ending.

3. The checksum characters are optional.

Response of OMR Commands

The response message depends on versatile OMR command. The response is composed with a few characteristics, including leading code, variables, and carriage return for ending. There are two categories of leading code for response message, ”!“ or ”>“ means valid command and ”?“ means invalid. By checking the response message, user can monitor the command is valid or not.

Note : Under the following conditions, there will have no response message.

1. The specified address ID is not exist.

2. Syntax error.

3. Communication error.

4. Some special commands do not have response.

3-2 Command Set

3. 2. Summary of Command Set

There are three categories of OMR commands. The first is the general commands, including set configuration command, read configuration, reset, read module‘s name or firmware version, etc. Eve ry OMR can response to the general commands. The second is the functional commands, which depends on functions of each module. Not every module can execute all function commands. The third is the special commands including functions about the programmable watchdog timer, safe values, and the programmable leading code. All the commands used in the OMR analog input module are list in the following table.

1. Engineering units

2. Percent of FSR (Full Scale Range)

3. Two’s complements hexadecimal

4. Ohms

Engineering Units

• Set bit 1 and bit 0 of data format variable to “00” means the data is represented in engineering units.

• This data format including three components.

1. sign (+ or -)

2. digits

3. decimal point

• Data is composited with a sign (+ or -) followed with 5-digits and a decimal point.

• It does not exceed 7-characters.

The different analog input ranges have different resolutions or number of decimal places. Refer to Table 4-1 for details.
