9.1 Config File Title
This is simply a comment at the start of the file describing its function, version history, etc.
The FloBoss S600+ ignores this comment.
9.1.1 Config File Header
This block, used by both master and slave links, is mandatory. Four commands are
supported, all of which are enclosed in brackets ([]):

[TX BUFF SIZE <NNNN>]

[RX BUFF SIZE <NNNN>]
These lines determine the size in bytes of the message transmit (TX) and receive
(RX) buffers. For normal Modbus operation set them both to 1024 which is the
maximum message size serial Modbus supports.

[MSG LENGTH MODE <mode>]
This field determines how the message length (Byte Count) of the Modbus message
is handled (refer to Section 7, Message Length Mode for more information). The basic
Modbus specification defines this field as a single byte which defines the number of
bytes of data in the message. However, many implementations change this field to
be an item count, such as the number of data items in the message.
Additionally, to increase the amount of data which may be transferred, the FloBoss
S600+ supports a 16-bit value for this field. This is not compatible with standard
Modbus and is used only when communicating with compatible systems, such as
the legacy Daniel DMS supervisory. It should not be used for any other third-party
devices.
The available values for <mode> are:
• BYTE_8
• BYTE_16
• ITEM_8
• ITEM_16

[CHECKSUM <status>]
This field is used to enable or disable checksum checking on received data. It is
intended for test purposes only. The available values for <status> are.
• TRUE
• FALSE
