Troubleshooting
–199 to –100: Command Errors
–100 Command error
This is a generic syntax error for devices that cannot
detect more specific errors. The code indicates only that
a command error as defined in IEEE 488.2, 11.5.1.1.4
has occurred.
–110 Command header error
An error was detected in the header. This message is
used when the device cannot detect the more specific
errors described for errors –111 through –119.
–104 Data type error
The parser recognized a data element that is not
allowed. For example, numeric or string data was
expected, but block data was encountered.
–123 Exponent too large
The magnitude of an exponent was greater than 32000
(see IEEE 488.2, 7.7.2.4.1).
–170 Expression data error
This error, as well as errors –171 through –179, is
generated when parsing an expression data element.
This particular error message is used if the device
cannot detect a more specific error.
–178 Expression data not allowed
A legal expression data was encountered, but was not
allowed by the device at this point in parsing.
–105 GET not allowed
A Group Execute Trigger was received within a
program message (see IEEE 488.2, 7.7). Correct the
GPIB controller program so that the GET does not occur
within a line of GPIB program code.
–111 Header separator error
A character which is not a legal header separator was
encountered while parsing the header.
