Error Description
−100 Command error — This is the generic syntax error for devices that cannot
detect more specific errors. This code indicates only that a Command Error
has occurred.
−101 Invalid character — A syntactic element contains a character which is
invalid for that type; for example, a header containing an ampersand,
SETUP&. This error might be used in place of errors −114, −121, −141, and
perhaps some others.
−102 Syntax error — An unrecognized command or data type was encountered;
for example, a string was received when the device does not accept strings.
−103 Invalid separator — The parser was expecting a separator and encountered
an illegal character; for example, the semicolon was omitted after a
program message unit, *EMC 1:CH1:VOLTS 5.
−104 Data type error — The parser recognized a data element different than one
allowed; for example, numeric or string data was expected but block data
was encountered.
−105 GET not allowed — A Group Execute Trigger was received within a
program message.
−108 Parameter not allowed — More parameters were received than expected for
the header; for example, the *EMC common command only accepts one
parameter, so receiving *EMC 0,1 is not allowed.
−109 Missing parameter — Fewer parameters were received than required for
the header; for example, the *EMC common command requires one
parameter, so receiving *EMC is not allowed.
−110 Command header error — An error was detected in the header. This error
message should be used when the device cannot detect the more specific
errors described for errors −111 through −119.
−111 Header separator error — A character which is not a legal header separator
was encountered while parsing the header; for example, no white space
followed the header, thus *GMC"MACRO" is an error.
