Test by Communication

Test by communication support the following three commands:

• On Load Test

• Off Load Test

• Test Exit

When more than one Modbus modules are installed, the ATSE will only response to the module which send the command first. It will not response to any command from other modules until the first module send the Test Exit command.

When the test is ongoing, ATSE ignores any other signal from active automatic HMI or DI module (TPCDIO07).

The operation of Test by communication is equivalent to Test mode. For more information, see Test Mode

Stop Test by Communication

There are three ways to stop the test:

• The Modbus master device send Test Exit command to the active Modbus module installed on ATSE.

• Turn off Test by Comm from active automatic HMI.

• The active Modbus module is offline.
