6-2 Command Language
Name
The Name field refers to a C style variable for function names
associated with the transaction. Use of these names is not
necessary to interface with the transaction. These names may
be used in present and future software drivers and libraries
provided by Baldor. When used in conjunction with Baldor
software tools, the transaction name is case sensitive.
Type
There are three basic transaction types: Set, Get, and those
which do both: Set/Get.
S Set transactions are used to change internal values, or
execute onetime (nonmodal) commands. As a general rule
most set transactions pass data to the control, but do not
return any. Most execution set commands do not pass or
return data.
S Get transactions are used to retrieve internal values or
control conditions. Most get transactions return data but do
not pass data.
S Set/Get transactions do both functions. Usually these
transaction always return data, but only accept or pass data
when a set or change function is occurring. When no data is
passed, the Set/Get functions as a Get or readonly
transaction.
When a transaction does not fit these general rules, both passed
and returned data fields will be clearly specified.
