Controller Response to DATA
The DMC-18x2 returns a : for valid commands.
The DMC-18x2 returns a ? for invalid commands.
For example, if the command BG is sent in lower case, the DMC-18x2 will return a ?.
:bg <enter>
?
When the controller receives an invalid command the user can request the error code. The error code
will specify the reason for the invalid command response. To request the error code type the
command: TC1 For example:
TC1 <enter>
1 Unrecognized command
There are many reasons for receiving an invalid command response. The most common reasons are:
unrecognized command (such as typographical entry or lower case), command given at improper time
(such as during motion), or a command out of range (such as exceeding maximum speed). A complete
listing of all codes can be found in the Command Reference under TC.
Interrogating the Controller
Interrogation Commands
The DMC-18x2 has a set of commands that directly interrogate the controller. When the command is
entered, the requested data is returned in decimal format on the next line followed by a carriage return
and line feed. The format of the returned data can be changed using the Position Format (PF), Variable
Format (VF) and Leading Zeros (LZ) command. See Chapter 7 and the Command Reference.
