Introduction
This tutorial is intended as a supplement to the original manuals for the products. Therefore, use it to familiarise yourself with the product but not as a guide to complete installation. The information in the tutorial is taken from the manual (s):

Product Information
This is a separate suite (Modbus_Master ver 8.cxp) used to control the drives from a CPM2A, CPM2C, CQM1H, CJ or CS. Communication takes place in the Modbus serial, which uses a binary protocol. The PLC is the Master and the inverter is the Slave. The program can handle up to 8 drives on the CPM / CQM, and 15 converters in CJ1/CS1. The serial communication is 2 or 4-wire RS422/RS485. The program also takes 2.5kW memory (CPM2x, for example, a total of 4kW).
Use CPM2C with CPM2C-CIF11, for example, to connect the frequency converter directly. CJ1 and CS1 with CJ1W-CIF11 can also connect directly to the inverter.
The protocol reads and writes the following to the inverter's Holding Register:
Using the program
Setting the frequency converter
The following parameters must be set in the inverter:
br />RTS Control is used in 2-wire RS485 or when there is more than 1 slave.
Set n001 or A1-01 back to 1 after the configuration is done. Turn the power on the power adapter for it to be updated with the new settings.

Use shielded cable for this.
Remember to connect the end resistance in the PLC and in the furthest inverter.
Addresses in the PLC
CPM2x and CQM1H
DM1009 to DM1000 and IR201 to IR209 are reserved for the inverters. The highlighted number refers to the slave number. Therefore, slave number 3 has IR203-DM1039 and DM1030. x in the table is the slave number.
CJ1 and CS1
D1000 to D1159 and W201 to W215 are reserved for the inverters. The highlighted number refers to the slave number. Therefore, slave number 3 has W203 (shown as 2xx in the table below), and D1030-D1039. xx in the table is the slave number.
The following addresses used by the protocol:
Customisations
For those who wish to read other data from the inverter they must make a change in the Holding Register reading table. This can be done in the DM2000-DM2008. Be sure to add the number as a two-digit Hex value. The result of the reading for that node can be found in DM1xx0 to DM1xx8. Reading the table is common to all slaves. Remember that the response time increases for each additional holding register you place in the table to be read. The following values are the defaults in this reading table. :
Useful information
The protocol can carry approximately 15 messages per second with baud rate 9600. It sends a message as type 1 for each message read. With 8 slaves, all of the slaves have received your message + read a message within 1 second. This is carried out at the expense of reading which means that the reading of 6 messages per slave would entail the update of the PLC taking up to 6 seconds.

This is a separate suite (Modbus_Master ver 8.cxp) used to control the drives from a CPM2A, CPM2C, CQM1H, CJ or CS. Communication takes place in the Modbus serial, which uses a binary protocol. The PLC is the Master and the inverter is the Slave. The program can handle up to 8 drives on the CPM / CQM, and 15 converters in CJ1/CS1. The serial communication is 2 or 4-wire RS422/RS485. The program also takes 2.5kW memory (CPM2x, for example, a total of 4kW).
Use CPM2C with CPM2C-CIF11, for example, to connect the frequency converter directly. CJ1 and CS1 with CJ1W-CIF11 can also connect directly to the inverter.
The protocol reads and writes the following to the inverter's Holding Register:
| Reading | Writing |
| 20H I/O-Status | 1H Inputs/Outputs |
| 21H Alarm Status | 2H Frequency reference, Set in fractions of Hz for MV / JV and one hundredths Hz for PV / RV can be entered as a decimal item & 100 |
| 24H Frequency | |
| 27H Current | |
| 38H PID Feedback | |
| 2BH S1-S7 Input Status |
Using the program
- The program is loaded into the PLC normally. Once this is done click on Settings.
- Make sure you transfer the DM1000-DM2047. This data appears as open DM in Memory. Check the site and press Transfer to PLC.
- Turn the power on the PLC to ensure the port setting is correct.
- Enter the maximum number of slaves for DM1000.
- The program is now ready for use and will immediately try to reach the nodes.
