This section describes each message sent or understood by the Equipment.

 60/1RWDWLRQ

Message descriptions are shown using "SECS Message Language" (SML) notation. SML

is a general notation developed by GW Associates for describing SECS messages. SML

is similar to the notation used in the SECS Standards documents, but SML is a more

precise and regular notation. In SML, the format for a data item is as follows:

< type [ count ] value >

The components are:

! Angle Brackets. Each Data Item is enclosed within angle brackets ("less

than", "greater than"). This notation implies that each Data Item has a

Data Item Format and Data Item Length as required by SECS-II.

W\SH This specifies the SECS-II Data Item format. It will have one of the

following values:

A ASCII

B Binary

JJIS-8

I1, I2, I4, I8 Signed Integers

U1, U2, U4, U8 Unsigned Integers

F4, F8 Floating Point

BOOLEAN True/False

FRXQWCount of the element values that make up the item. If present, the count

is enclosed within square brackets "[ ]". The count may be omitted, in

which case the square brackets are also omitted.

The "count" specifies the number of value elements in the Data Item

Value. For String formats (ASCII, Binary, JIS-8), "count" specifies the

number of characters in the string. For Numeric formats (I1, I2, I4, I8, U1,

U2, U4, U8, F4, F8, BOOLEAN), "count" specifies the number of values in

the array. For simple scalar numeric values, "count" is usually "1". For

LIST items, "count" specifies the number of items in the list.

If "count" is omitted, then the length of the Data Item is implied by the

value which follows. The "count" can range between known limits. It may

be specified as minimum and maximum "counts", separated by two dots.

(For example, [0..40]).

YDOXH Value of a single item element. Values are shown in a notation that

depends on the item type. For example, ASCII values are shown as

characters enclosed in quotes, Unspecified Binary values are shown in

hexadecimal.

 Ellipsis (...) is used to indicate additional elements may occur, as for

example where substructures may repeat in a List structure.

As an example, a two-byte unsigned integer Data Item with an array of three values 21,

22, and 23 is represented as:

Numeric values shown are considered decimal integers unless otherwise indicated.

negative values shown with a leading minus sign "-". Hexadecimal values are shown in C-

Language convention, with a leading "0x".

10 Decimal Ten

0x10 Hexadecimal 10

-10 Decimal Negative 10

Where a value is not fixed, the SECS variable name is used directly. For Example:

The format of a complete message is:

SnFn W item .

The components are:

6Q)Q The Stream and Function Codes, S1F1 for example.

: The W-Bit, if set. Omitted if not set. If the W-Bit is optional, it is coded

within brackets "[W]".

LWHP An item that is formatted as described above.

 A period (.) ends the message definition.

For example, the S1F3 message might be described in SML as follows:

S1F3 W

<U4 13>

<U4 7>

> .
