SYSTem:ABUS:INTerlock:SIMulate
Syntax
SYSTem:ABUS:INTerlock:SIMulate <mode>
SYSTem:ABUS:INTerlock:SIMulate?
Description
The Safety Interlock feature prevents connections to the Analog Buses if no terminal block or properly-wired cable is connected to the module. Normally, if you attempt to connect to the Analog Buses without a terminal block or properly-wired cable connected, an error is generated. This command allows you to temporarily disable errors generated by the Safety Interlock feature. This may be useful during test system development when you may not have connected any terminal blocks or cables to your module.

|
The Safety Interlock feature is implemented in hardware on the modules and cannot be circumvented. Regardless of whether the simulation mode is enabled or disabled, all Analog Bus connections are disabled as long as no terminal block or properly-wired cable is connected to the module. |
Used With:
34921A through 34925A Multiplexer Modules
34931A through 34933A Matrix Modules (this command does not apply to the 34934A)

Remarks
This command applies to the entire mainframe and cannot be selectively used on individual modules.
When the simulation mode is enabled, the Analog Bus relays will appear to close and open as directed. For example, no errors are generated if you close an Analog Bus relay from the front panel, remote interface, or Web Interface. However, remember that the Safety Interlock feature prevents the actual hardware state of the Analog Bus relays from being changed. Note, however, that when you connect a terminal block or cable to the module, the Analog Bus relays will be closed.
The simulation setting is stored in volatile memory and will be disabled (OFF) when power is turned off or after a Factory Reset (*RST command). The simulation setting will also be disabled (OFF) when a stored state is recalled (*RCL command). To re-enable the simulation mode, send SYSTem:ABUS:INTerlock:SIMulate ON.
Return Format
The query command returns "0" (OFF) or "1" (ON).
Examples
The following command enables the Safety Interlock simulation mode. Although Safety Interlock errors are suppressed in this mode, all Analog Bus connections are prohibited as long as no terminal block or cable is connected to the module.
SYST:ABUS:INT:SIM ON
The following query returns the setting of the Safety Interlock simulation mode.
