1-1 Overview of Communications Methods

Introduction
3G3JE Inver ters with Communications (referred to as “Communications Models”) use communica­tions to monitor set values and make settings. In addition, programs for communications are created at the Inverter's host computer (e.g., a personal computer), and the host computer is used to read and write data, send operation commands, and change the setup area. Therefore the description provided here is from the viewpoint of the host computer.
CompoWay/F is OMRON's standard communications protocol for general serial communications. This protocol uses a stan dard frame format, as well as commands conforming to the well-establ is hed FINS* commands used for OMRON PLCs. This simplifies communications between the host com­puter and components.
*FINS (Factory In terface Network Serv ice) The FINS protocol pro vides message communications between controllers in OMRON FA networks.
The 3G3JE supports the following communications functions.
• Reading/writing parameters
• Operation commands
• Changing the setup area

2-1 Data Format

This section describes the procedures for communications according to the CompoWay/F protocol.
• Hexadecimal values are expressed by adding the prefix H' before the number, e.g., H'02.
• Numbers shown without the H' prefix are ASCII characters. (For a tabl e of ASCII codes, ref er to the appendix.)
• The number underneath each item in a frame indicates the number of bytes.
Command Frame
Text
Node number
STX
1
Name Description
STX • This code (H'02) indicates the beginning of the communications frame (text).
• Always set this character in the first byte.
• If STX is received aga in dur ing recep tion, rec eption is carr ied out ag ain from the point where STX w as received.
Node number • This number specifies the transmission's destination.
• Specify the 3G3JE's communications unit number.
• A BCD value between 00 and 99 or ASCII “XX” can be set.
• Specify “XX” for a broadcast transmission. No responses will be returned for broadcast transmissions.
• No resp onses will be returned f rom node numbers other than the ones in the above range.
Sub-address • The sub-address is not used with the 3G3JE.
• Always set the sub-address to “00.”
SID • This is the service ID.
• The service ID is not used with the 3G3JE.
• Always set the service ID to “0.”
Command text This is the command text area. For details, refer to 2-2 Structure of Command Text. ETX This code (H'03) indicates the end of the text. BCC • This is the Block Check Character.
• The BCC result is found by calculating the exclusive OR of all bytes from the node num­ber through ETX.

BCC Calculation Example
Chapter 2
The BCC (Block Check Character) is determined by calculating the exclusive OR of the bytes from the node number through ETX. The 8-bit result is written to the BCC b yte at the end of the frame.
STX Node number
H'02 0 (H'30)
BCC = H'30 + H'30 + H'30 + H'30 + H'30 + H'30 + H'35 + H'30 + H'33 + H'03 = H'35
The result of the calculation (H'35) is written to the BCC byte.

The following examples show the end code when a command did not end normally.
Example 1: Illegal Sub-address, No SID, and No Command Text
• If there is an illegal sub-address , and no SID or command te xt, the resp onse end code will be 16 (sub-address error). (If the sub-address is received, the response end code is 16 because a sub-address error has a higher error detection priority than a format error.)

Chapter 2
•RUN/STOP Command code 01 is used to start and stop operation. It is also used to clear error s when an error has occurred or a pr otective functi on has operated. R UN/ST OP can be used only in setup area 0.
• Frequency References 1 to 4 Command code 02 is used to switch between four frequency references that are set in ad­vance. All four frequency references can be recorded in t he Inverter. Frequency References 1 to 4 can be used only in setup area 0.
• Forward/Reverse Operation Command code 03 is used to change the direction of motor rotation and can be used regard­less of the RUN/STOP status. The direction will return to f orwa rd rotation whenever the power supply is turned ON or setup area 1 is entered. An operation error will occur if reverse opera­tion is set in the related information when reverse operation is prohibited. The Forward/Re­verse Operation can be used only in setup area 0.
• Write Mode Command code 04 is used to set the mode for writing frequency references using communi­cations. The Write Mode can be used only in setup area 0. (The default setting for the write mode is Backup Mode.)
• Backup Mode: The frequency reference is written to EEPROM using communications.
• RAM Mode: The frequency reference cannot be written to EEPROM using communications. Chang­es to the frequency reference made with key operations are writ ten each ti me to EEPROM. When frequently changing the frequency reference, use RAM Mode.
• Save RAM Data Command code 05 is used to write the frequency reference to
RAM data can be saved in setup area 0 or 1. The write mode will not be changed.
EEPROM usin g co mm un i c at io ns.
• Paramet er Initialization Command code 06 is used to initialize all parameters except for the Accumulate Operating Time to their default values. Parameters can be initialized only in setup area 1.
2-14
Page 36
CompoWay/F Communications Procedures
• Software Reset Command code 07 is used to start the processing that occurs when the power is turned ON. A software reset can be performed in setup area 0 or 1. (There is no response to this com­mand.)
• Move to Setup Area Command code 08 is used to change the setup area under the f ollo wing conditions . Changing the setup area can be performed in setup area 0 or 1.
• Operation must be stopped to move from setup area 0 to 1.
• Moving from setup area 1 to 0 is possible at any time.
• Accumulated Operating Time Clear Command code 09 is used to clear the Accumulated Operating Time of the motor to 0.0 (0 h) . The Accumulated Operating Time can be cleared onl y in setup area 1.
