Controller Response to DATA
The DMC-40x0 returns a : for valid commands and a ? for invalid commands.
For example, if the command BG is sent in lower case, the DMC-40x0 will return a ?.
invalid command, lower case
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:
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 is listed in the TC
command in the Command Reference section.
Interrogating the Controller
Interrogation Commands
The DMC-40x0 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 357HChapter 7 and the Command Reference.
