Appendix A: Model 2090 GPIB Command Reference
Model 2090 Multi-Device Controller
IEEE 488.2 Mandatory Instruction Set:
*CLS
Description:
Clear Status. Clears all Event Registers summarized in the Status Byte
Register and places the controller in the Operation Complete Idle State.
Devices:
Towers, Turntables
Syntax:
*CLS
Example:
CALL ibwrt (TowerUD%, "*CLS")
' Clear status registers
See Also:
*ESR?, *OPC, *RST, *STB?
*ESE
Description:
Set Standard Event Status Enable Register. Causes changes in the contents of
the Standard Event Status Enable Register. Requires an integer argument in
binary form to set the register. The bits of the argument correspond to the
bits of the Standard Event Status Register. Setting a bit in this register allows
the corresponding bit in the Standard Event Status Register to cause the Event
Status Bit in the Status Byte Register to be set.
Devices:
Towers, Turntables
Syntax:
*ESE XXX
XXX
Integer value representing eight bit binary number 0-
255
Example:
CALL ibwrt (TableUD%, "*ESE 16")
' Allow an Execution Error to
' set the ESB
See Also:
*ESE?, *ESR?, *STB?
*ESE?
Description:
Query Standard Event Status Enable Register. Prepares the controller to
respond with the contents of the Standard Event Status Enable Register when
queried. Value returned is an integer number in the range of 0 to 255. This
value, when expressed in binary form, represents bit values of the Standard
Event Status Enable Register.
Devices:
Towers, Turntables
Syntax:
*ESE?
Response:
XXX
Integer value representing the setting of the Event
Status Enable Register
Example:
CALL ibwrt (TableUD%, "*ESE?")
' Query ESE register
CALL ibrd (TableUD%, rdbuf$)
' Read response
See Also:
*ESE?, *ESR?
