SOFBUS/LACBUS (IPS) tab

The SOFBUS/LACBUS protocols are the intellectual property of LACROIX Sofrel.

SOFBUS/LACBUS are industrial application protocols that are mainly used in water management infrastructures to conduct remote management, i.e., monitoring and controlling industrial sites remotely. 

These protocols are encapsulated in the MODBUS protocol, which is also an industrial application protocol that uses TCP as its transport protocol.

Enable SOFBUS/LACBUS analysis in MODBUS packets

Enables or disables the analysis of the SOFBUS/LACBUS protocol in MODBUS packets. The default configuration of the SOFBUS/LACBUS analysis in the firewall complies with LACROIX Sofrel specifications.

Managing Information units (IU) and SOFBUS or LACBUS blocks

The grid lists the Information units (IU) and SOFBUS or LACBUS blocks. Each IU may contain several blocks. Each item has a name, letter, action and type.

IUs and blocks are created by default in the configuration, and can be identified by their type: Default IU or Default block. These can be found in the technical characteristics provided by LACROIX Sofrel and therefore make up the default configuration. They cannot be renamed, moved or deleted, but the associated action can be changed for: Allow or Block.

The default configuration can be customized when necessary. The Add an IU or a block button makes it possible to add a Custom IU or Custom block to an existing IU. There are rules regarding the use of letters:

• IU letter: must be in uppercase. No two IUs can have the same letter.

• Block letter: can be uppercase or lowercase. No two blocks in the same IU can have the same uppercase or lowercase letter (case sensitive).

Custom IUs and block can be renamed and moved as long as the rules on the use of letters are followed, but the associated action cannot be changed.

The Delete button makes it possible to delete a Custom IU or Custom block. Default IUs and Default blocks cannot be deleted.
