For MODBUS TCP/IP protocol configuration add a new object for MODBUS Server settings under ETHERNET Interface. In the device tree double-click the new added item to open the configuration:
The following parameters are available:
Parameter | Default | Value | Meaning | Generic see remark 1 |

Disable write to %MB0.x from | 0 | 0…65535 | Disable write access for segment 0 starting at %MB0.x | Disable write to %MB0.x from |
Disable write to %MB0.x to | 0 | 0…65535 | Disable write access for segment 0 up to %MB0.x | Disable write to %MB0.x to |
Disable read to %MB0.x from | 0 | 0…65535 | Disable read access for segment 0 starting at %MB0.x | Disable read to %MB0.x from |
Disable read to %MB0.x to | 0 | 0…65535 | Disable read access for segment 0 up to %MB0.x | Disable read to %MB0.x to |
Disable write to %MB1.x from | 0 | 0…65535 | Disable write access for segment 1 starting at %MB1.x | Disable write to %MB1.x from |
Disable write to %MB1.x to | 0 | 0…65535 | Disable write access for segment 1 up to %MB1.x | Disable write to %MB1.x to |
Disable read to %MB1.x from | 0 | 0…65535 | Disable read access for segment 1 starting at %MB1.x | Disable read to %MB1.x from |
Disable read to %MB1.x to | 0 | 0…65535 | Disable write access for segment 1 up at %MB1.x | Disable read to %MB1.x to |
Like for MODBUS RTU on the serial interfaces COMx, it is also possible to disable read and/or write access to individual segments for slave operation. Reading/writing is disabled beginning at the set address and is valid up to the set end address (inclusive).
