GPIB Messages

F.2 GPIB Messages

Command Errors

These are error messages in the range -100 to -199. They indicate that a syntax error has been detected by the parser in a command, such as incorrect data, incorrect commands, or misspelled or mistyped commands.

A command error is signaled by the command error bit (bit 5) in the event status register.

-100 Command error

This indicates that the parser has found a command error but cannot be more specific.

-101 Invalid character

The command contains an invalid or unrecognized character.

-102 Syntax error

The command or data could not be recognized.

-103 Invalid separator

The parser was expecting a separator (for example, a semicolon (;) between commands) but did not find one.

-104 Data type error

The parser was expecting one data type, but found another (for example, was expecting a string, but received numeric data).

-105 GET not allowed

A Group Execute Trigger was received within a program message (see IEEE 488.2, 7.7)
