Message Communications This section describes how to read/write inverter parameters by the Message commu- nications function (CompoNet Explicit Message). 5-1 Outline of Explicit Message ........5-2 5-2 Sending Messages from CS/CJ-series .
5 Message Communications Outline of Explicit Message Explicit Message is a Message communications function defined in the CompoNet specifications. It uses the Node Address, Service Code, Class, Instance, Attribute, and other data to achieve Message communications. Because the communications frame of an Explicit Message is standardized in the CompoNet specifications, the CompoNet Communications Unit can perform Message communications even with third-party Masters.
5 Message Communications Sending Messages from CS/CJ-series This section describes how to send/receive messages using the Master Unit (Model: CS1W-CRM21/ CJ1W-CRM21). 5-2-1 How to Issue Explicit Messages by CMND Instruction The Master Unit (Model: CS1W-CRM21/CJ1W-CRM21) uses the CMND instruction to issue Explicit Messages.
Page 122
5 Message Communications D: First Word Address of Response Storage Area Set the first word address of the area to store the response to the Explicit Message. Precautions for Correct Use Precautions for Correct Use • When the CMND instruction issues an Explicit Message, due to the following reason, the attachment data to the Explicit Message is sent in reverse order of high and low bytes.
5 Message Communications C: First Word Address of Control Data Set the first word address to configure the required control data for Message communications. The CompoNet Master Unit requires to be previously set the following control data to consecutive word addresses.
Page 124
5 Message Communications When to Read Response to an Explicit Message The response to an Explicit Message must be read at the rising edge of the Network Communications Command Execution Enabled Fag for each communications port. Network Communications Command Execution Enabled Flag Response Read Process Flags Related to CompoNet Communications Address...
5 Message Communications Outline of Message Function and Response When using the Message function, the CompoNet Communications Unit on the inverter returns the response in the following method. In CompoNet communications, data is sent/received basically in units of 1 byte (8 bits). For single-word (16-bit) data, the order of high and low bytes will be reversed due to the following rea- son.
Page 126
5 Message Communications The CompoNet Communications Unit supports the following service codes. Service Codes Service Description Read Write Reset Command 0E hex 10 hex 05 hex Normal response 8E hex 90 hex 85 hex Parameter Details Destination Node Address (Command) This parameter specifies the destination slave node address for the Explicit Message.
Page 127
5 Message Communications Description • The Explicit Message Send Command sends the Explicit Message defined in the CompoNet specifi- cations to a Slave Unit and receives a response. • For the Explicit Message Send Command, unlike other FINS commands, specify the CompoNet Master Unit as the destination of the control code in the CMND instruction and the actual destination node as the destination node address in the Explicit Message Send Command, respectively.
5 Message Communications Parameter Read/Write (Class 64 hex) Explicit messages can be used to read and write inverter parameters. The CompoNet Communications Unit provides the Instance and Attribute registers corresponding to each parameter of the inverter in Class64 hex (100 dec). According to the following instructions, set parameters in the corresponding Class, Instance, and Attribute registers to issue an Explicit Message.
5 Message Communications Precautions for Correct Use Precautions for Correct Use If single-word (16-bit) or double-word (32-bit) data is sent/received in an Explicit Message, the order of high and low bytes will be reversed due to the following reason. Therefore, in the Parameter Read/Write data, the Attribute value is located in high byte and the low byte of data is located in low byte.
5 Message Communications 5-4-4 Saving Changes to Holding Registers (ENTER Command) Using an Explicit Message to set data in each Attribute causes the new data to overwrite the existing data. However, this new data is not stored in EEPROM and will be lost when the inverter is powered off. To save changes to the holding registers into EEPROM, you need to issue the ENTER command using the method shown below.
5 Message Communications 5-4-6 Ladder Programming Example Ladder Programming Example The following is an example of a program that writes a value of 7.00 s (2BC hex in unit of 0.01 s) into parameter F002 1st Acceleration Time Setting (Modbus Register No. 1103 hex). Parameter F002 1st Acceleration Time Setting takes double-word data.

Troubleshooting This section describes the troubleshooting for various problems which may occur in CompoNet, the inverter, and the CompoNet Communications Unit. 6-1 Outline of Error Indication ........6-2 6-2 Errors on a Communications Line .
6 Troubleshooting Outline of Error Indication If an error occurs during CompoNet communications, or if the CompoNet Communications Unit fails, you can check the content of the error with the LED indicator on the inverter Digital Operator and the MS/NS LED indicators on the CompoNet Communications Unit. After eliminating the cause of the error according to the instructions provided in this section, reset the inverter.
6 Troubleshooting Errors on a Communications Line If the CompoNet Communications Unit cannot continue CompoNet communications due to interruption, short circuit, reverse connection, node address duplication, superimposed noise, or other cause, a transmission fault will be detected. If a transmission fault occurs, the inverter turns ON the fault contact to stop the motor (free run stop). In this case, check the LED indicator on the CompoNet Communications Unit and take corrective action.

6 Troubleshooting Errors Related to Message Communi- cations To send a CompoNet Explicit Message from a CS/CJ-series unit, use a FINS message. If any Explicit Message/FINS message is not completed normally, check the contents of the FINS mes- sage response. 6-4-1 FINS Message Errors (CS/CJ-series) The table below shows the assumed cause and corrective action for each FINS response.
6 Troubleshooting 6-4-2 Explicit Message Errors If there is an Explicit message that is issued but not completed normally, the response will be returned with one of the following error codes attached to service code 94. If this occurs, check the error mes- sage and correct the request message or otherwise resend the message in a timely fashion.
6 Troubleshooting Special I/O Errors If a problem is found in the output data of Special I/O, the inverter returns an error code to the input data without executing the request. Determine whether or not an error occurred by the most significant bit (word address n, bit 7) of the Function Code in the input data.
6 Troubleshooting Removing CompoNet Communica- tions Unit DANGER Do not attempt to remove the terminal block cover or disconnect and reconnect the CompoNet Communications Unit during power on or within 10 minutes after power off. Doing so may result in severe injury due to electric shock. Caution Inverters contain high voltage parts and short-circuits may sometimes cause product damage or property damage.
