Test Mode
Summary
Test Mode indicates that the output data of the STB island’s process image is not
controlled by a fieldbus master device, but is instead controlled by either the
Advantys Configuration Software or an HMI. When the STB island is operating in
Test Mode, the fieldbus master cannot write the STB island’s outputs, but can
continue to read its inputs and diagnostic data.
Test Mode is configured off-line, downloaded with the island configuration, then
activated online.
Select Test Mode Settings in the Online menu to open the Test Mode configuration
window, where you can select a test mode setting. Test Mode settings are stored
with other STB island configuration settings both in the NIM’s flash memory and in
a SIM card, if one is attached to the NIM.
When Test Mode is activated, the NIM’s TEST LED is lit, and bit #5 of the NIM Status
word in register 45391 is set to 1.
NOTE: Loss of Modbus communications do not affect Test Mode.
There are three Test Mode settings:
z Temporary Test Mode
z Persistent Test Mode
z Password Test Mode
The following sections describe the process and effect of activating Test Mode.
Temporary Test Mode
When operating online, use the Advantys Configuration Software (not an HMI) to
activate Temporary Test Mode, by selecting Test Mode in the Online menu.
Once activated, Temporary Test Mode is deactivated by:
z de-selecting Test Mode in the Online menu
z cycling power to the NIM
z selecting Reset in the Online menu
z performing Autoconfiguration
z downloading a new island configuration to the NIM (or inserting a SIM card with
a new island configuration into the NIM and cycling power to the NIM).
Temporary Test Mode is the default Test Mode configuration setting.
