Overview 1 Overview 1.1 Introduction You can use the Profibus option to connect the SV-iS7 inverter to the Profibus network. Using the Profibus communication board, the sequence program on the PLC or any Master Module can control and monitor the inverter. Because multiple inverters can be operated with one communication cable, this reduces the total installation cost.

Communication Profile 12 Communication Profile The communication profile represents the procedure for control commands (i.e., control word, status word, references, and actual values, etc.) between the Master and the Slave (inverter). Data transmission between the PROFIBUS DP Master and the Slave is performed through the IN/OUT data field. The Master controls the data by recording it in the OUT data of the Slave (inverter), the Slave (inverter) responds by delivering the contents of the IN data to the Master.
Communication Profile The Profibus DP communication module can be used in combination of process data and parameter data, depending on the use of the profile and Telegram. Process data Process data OUT : For controlling drive Process data IN : Is used for fast monitoring of the drive Parameter data Used for Write/Read parameters and variables.

Communication Protocol 13 Communication Protocol 13.1 Cyclical message types For the Profibus DP communication module and master to proceed with data exchange, set how many words of data you want to send and receive. Telegram settings are basically set by the Master during I/O configuration and cannot be set by the communication module itself.
Communication Protocol OUT area: Data (control data) sent from the Master to Slave. IN area: Data sent from Slave to Master (actual data). Parameter data area ID : Parameter identification(type and number) IND : subIndex of parameter Value : Request/Response Parameter value PKW : Parameter ID/value Process data STW1 : Control word...
Communication Protocol 13.1.3 Vender Specific Telegram Instead of using a separate standardized telegram, depending on the Para Control Num and the Para Status Num, the number of words to use is determined. PZD 1-8 is set according to the parameter address value specified in Para Control-1-8, Para Status-1-8.

Communication Protocol The parameter value can be set according to the read/write properties of each specified parameter, and the value of the requested parameter number can be read or changed. Only Byte 6 and 7 data are valid because they do not support 32-bit data, just 16-bit data.
Communication Protocol 13.2.2 Acyclic Parameter data transfer (DP-V1) It is a method of periodically requesting/responding parameters by accessing from Master class 2 without being dependent on a separate telegram type. The method to use the write/read service for the drive parameters is as follows: Figure 8.
