GPI Menu

The 7160 can be set up to allow an external device to trigger a switch through the GPI interface. The

GPI menu screen shown below allows conguration of the two external GPI inputs to the module.

The Primary GPI Mode can be set to one of the following:

O• – disables the GPI input.

Neg Edge Switch• – switches on a low-going transition to the GPI input.

Ext Fault Low• – acts in conjunction with the status of the input signal to the module. In this

case, a loss of proper signal to the module or a low signal detected from an external device will

close the switch.

Ext Inhibit Low• – acts to prevent a switch regardless of the status of the input signal to the

module. In this case, a loss of proper signal will not cause a switch.

Status of the Pri GPI input is indicated as GPI is Low or GPI is High in the Pri GPI Status window.
