Error −171 Invalid expression
The expression data element was invalid (see IEEE 488.2, 7.7.7.2); for example,
unmatched parentheses or an illegal character.
Error −178 Expression data not allowed
A legal expression data was encountered but was not allowed by the device at this point in
parsing.
Error −180 Macro error
This error, as well as errors −181 through −184, are generated when defining a macro or
executing a macro.
Error −181 Invalid outside macro definition
Indicates that a macro parameter placeholder was encountered outside of a macro
definition.
Error −183 Invalid inside macro definition
Indicates that the program message unit sequence, sent with a *DDT or *DMC command,
is syntactically invalid (see .
Error −184 Macro parameter error
Indicates that a command inside the macro definition had the wrong number or type of
parameters.
Error −200 Execution error
This code indicates only that an Execution Error as defined in IEEE 488.2, 11.5.1.1.5 has
occurred.
Error −201 Invalid while in local
Indicates that a command is not executable while the device is in local due to a hard local
control (see IEEE 488.2, 5.6.1.5). For example, a device with a rotary switch receives a
message which would change the switches state, but the device is in local so the message
can not be executed.
