<value1> First numerical parameter
The first character received after the command character begins evaluation of the first numerical parameter.
All non-numeric values with the exception of the field delimiter character will cause an error response.
A field delimiter character after the command character and before the first numerical character will be interpreted as
the first parameter having a value of zero. This means a zero character must be used to indicate an argument with
value of zero for the first numerical parameter.
<value2> Second numerical parameter
A null argument will be evaluated as a value of zero if there are no numerical characters between the field delimiter for
the first parameter and a following field delimiter. If there is a field delimiter for the first parameter, immediately
followed by the end of command character, it will be evaluated as having no second parameter.
<value3> Third numerical parameter
This is a read only parameter and all numerical values will be ignored. All values in the command string which are not
required by the command specified will be ignored.
Following is an example of a command string.
p1,100<CR> Command p1 (valving speed) a setting of 100%.
Transmission should stop when an ASCII carriage return character is sent and can resume when the ASCII carriage
return of the response is received.
Response String
The response from the Controller Module has a format which is very similar to the command with the addition of a
fault or warning value.
<name> Represents an argument
,
Field delimiter character for numerical arguments.
<CR>
End of command represented by ASCII carriage return character (no line feed).
The complete command form is:
<cmd><value1>,<value2>,<value3><C
R>
The description for the response string above follows the structure of the command string previously described except
for value3 which is a warning or fault code. Some responses to errant command strings contain special identifiers in
the <cmd> location.
Commands
The command set controls the overall settings of the system. Tables 3.3 list the commands.
NOTE
Refer to previous description for complete command syntax (“COMMAND STRUCTURE”).
<value3> has been omitted from the response in this table, but will either be a 0 if no faults or warnings
exist, or will provide the fault or warning number.
