COMMUNICATION DATA
All programmable, selectable, or switchable functions of the target system are accessible via the RS-232,
with the exception of the RS-232 configuration itself, which may not be programmed from the host.
All data, programmed values, status, and system errors are accessible by the host, i.e., an appropriate query
by the host will result in a data stream returned from the system as defined below.
DATA FORMAT
All data is transmitted in ASCII. All data values are transmitted via decimal character strings. Upper and
lower case alphabetic characters will be accepted interchangeably. Data descriptions are identified by
direction from the perspective of the system controller:
Received (from the host system to the MPC/EDC) and Transmitted (from the MPC/EDC to the host) data.
RECEIVED DATA
Data may be transmitted at any time by the host. Status queries will be answered whether or not the unit is
in local or remote. Any change in system status (except "Goto Remote") requested via the RS-232,
however, will require that the unit be in the "remote" state; otherwise an error will be reported to the host.
Data uses a "line" format, consisting of the following:
CMD <opt CMD> <opt CMD> <...> CR <opt LF>
where:
CMD is any valid transmitted data string
CR is an ASCII "Carriage Return"
LF is an ASCII "Line Feed"
Data commands may be grouped within a "line" command, or transmitted singly.
A data string must be terminated by a "Carriage Return" (ASCII 013 decimal / 0D hex). "Line Feed"
(ASCII 010 decimal / 0A hex) may be optionally inserted by the host, but will be ignored. A "line" may
not exceed 128 characters.
A listing and description of the available CMD statements appears in a later section.
Data commands which are grouped on a line must be separated by a single "Space" (ASCII 032 decimal /
20 hex).
The Delete/Rubout character (ASCII 127 decimal / 7F hex) will NOT be recognized. Unrecognized
characters will result in an error acknowledge.
ANY error in transmission/reception of a "line" will assume corruption of the ENTIRE line, and ALL
commands in that line will be ignored. This includes not only transmission (e.g., parity) errors, but values
out-of-bounds, undefined commands, etc. This ensures that state changes are not presented to the system
(e.g., new Setpoint SP) without all corresponding desired changes (such as corresponding PID values).
All data received by the target system will be presented by the host system as a character string of one of
the following formats:
1) Absolute Command
Basic system functions/commands will consist of a fixed character string.
