Modbus TCP/IP Filtering


The Modbus TCP/IP Filtering page allows you to define the level of access for Modbus TCP/IP clients connected to IFE interface.

Block Connections

You can select the maximum number of IP connections allowed, 8 or 16. Each connection can have 12 concurrent transactions simultaneously.

NOTE: When the maximum number of IP connections is changed, a message pops-up on the screen Max Connection is changed. Restart the Device to Take Effect and prompts to restart the device.

If IP Filtering is enabled, you must configure the IP address of the PC in the list of allowed addresses with read/write permission for using the EcoStruxure Power Commission software.
