1.6 Protocol parameter
Table 1-8 Protocol parameter description
| Function code | Communication protocol | Description |
| P7.83— P7 91 |
PROFINET | • Supports the PROFINET protocol, accommodating PROFINET 10 devices, medium redundancy protocol (MRP), and system redundancy protocol (S2). Equipped with the slave station GSDML configuration file, it can communicate with Siemens PLC and other master stations. • Enables basic operations on VFDs, such as reading and writing process values, reading status values, and reading/writing function codes. This communication card supports up to 3210s. • Applicable to linear, star, and ring network topologies. |
| EtherCAT | • Configured with a slave XML configuration file, communication between the master stations (such as Beckhoff PLCs and INVT controllers) and the VFD can be established. It supports up to 32 bytes of I/O data exchange but does not support CiA301 or CiA402 EoE protocols. • Supports PDO services and manufacturer-defined object dictionaries, meeting the EtherCAT compliance testing certification requirements within the factory. • Applicable to linear, star, and ring network topologies. • Equipped with two RJ45 ports, designated for IN and OUT directions. |
|
| PowerLink | • Configured with a slave station XDD configuration file, communication between master stations (such as B&R PLCs) and the VFD can be established. The CiA401 protocol is not supported. • Supports PDO services and manufacturer-defined object dictionaries for communication with the VFD • Applicable to linear and star network topologies. |
|
| EtherNet IP | • Supports ODVA standards and DLR ring protocol. When configured with a slave station EDS configuration file, it can communicate with Rockwell PLC and other master stations. • Enables basic operations on VFDs, such as reading and writing process values, reading status values, and reading/writing function codes. This communication card supports up to 3210s. • Applicable to linear, star, and ring network topologies. |
|
| Modbus TCP | • Supports the Modbus TCP protocol. A Modbus TCP slave station can communicate with multiple master stations simultaneously. It can communicate with Schneider PLC, INVT controllers, and other master stations. • Enables basic operations on VFDs, such as reading and writing process values, reading status values, and reading/writing function codes. • Applicable to linear and star network topologies. |
Note: After each change to P7.8-P7.91, the expansion card will automatically reset and complete the protocol switchover. It will take some time to re-establish communication with the PLC using the new protocol. If a communication timeout fault occurs on the VFD during this period, you can clear it by pressing the reset key on the keypad.

Note:
- When two identical expansion modules are inserted into a VFD simultaneously, only the module in the slot with a smaller number will be active, while the module in the slot with a larger number will be redundant. For example, if two PROFINET expansion modules are inserted into slot 1 and slot 2, the PROFINET module in slot 1 will be active.
