6.7.5 Device Address
The Device Address consists of a Physical Address. For this document DEV is used for
the generic case examples.
For Example; <10 direct addressing
<10V2 indirect addressing
6.7.6 Command
A Command is a variable length character string beginning with a / and containing either
an instruction or an instruction and data for an KPA to act upon.
•
If data is passed by command, it is appended to the instruction by an
underscore( _ ).
•
If data is retrieved by command, underscore follows the instruction flagging
the KPA to supply data in a response.
•
In this document /COM is used for the generic case examples.
For Example: <DEV/COM_xxx'cr' Sends data to an KPA.
For Example: <DEV/COM_'cr' Requests information from an
KPA.
6.8 Confirmation Response
A confirmation will change the start character, and echo the Device Address and
Command. Any requested data will be appended to the Command.
For Example: >DEV/COM_xxx'cr''lf']
6.8.1 Error Response
If an KPA cannot execute a Command or detects a protocol violation, an error response is
generated. An error is flagged by changing the "/" command designator in the response to
a "?". Following the "?" error symbol are two characters which are unique error symbols
useful for computer analysis. The two error symbols are followed by a text string
explaining the error for the convenience of a human operator. For this document ER is
used for the generic case examples response.
For Example: >DEV?COM ER Error Message 'cr''lf']
