Messages
Notation
The individual message sections are each to be separated by a space (ASCII code 32,
20h).
1)
The LMS interprets the parameters transferred as follows:
•
Parameters with a leading “+” or “–” are interpreted as a decimal value (ASCII notation).
•
Parameters without a leading “+” or “–” are interpreted as a hexadecimal value (ASCII
notation).
•
The LMS interprets each parameter individually, i.e. the different notations can be
mixed within a message.
•
All examples used in the following message lists refer to the CoLa-A protocol.
Variable types
The variable types are given in the message syntax. The following variable types are
possible:
Important
•
The information in the “Length” column of the table refers to the binary transfer of the
numeric parameters.
•
The information in the “Value range” column in the table refers to the value range
mathematically possible for the variable type. The actual value ranges for the
parameters may be different. You will find these in the message syntax that follows.
1)
In the examples “{SPC}” is used for “space”.
