If you want to check the effects of a binary input without actual switching operations
in the plant, you could do so by controlling individual binary inputs with the hardware
test. As soon as you have initiated the first state change for any binary input and have
entered the password No. 6, all binary inputs are disconnected from the device and
can only be operated by the hardware test functions.
Finish the testing (see margin heading below "Finishing the process").
You can check the LED in the same way like the other in/output components. As soon
as you have initiated the first state change for any LED, all LEDs are disconnected
from the functionality of the device and can only be operated by the hardware test
function. This means e.g.that no LED is illuminated anymore by a protection function
or by pressing the LED reset button.
During the opening of the dialog box Test devices in and outputs the operating
states of the hardware components which are current at this time are read in and dis-
played. An update is made:
• for the particular hardware component, if a command for the change on a other
state was successful.
• for all hardware components by clicking the box Update,
• for all hardware components by cyclic updating (cycle time is 20 seconds) by high-
lighting the option Automatic Update
To finish the process, click Close The dialog box is closed. The hardware components
are again reset to the original operating state determined by the plant conditions. The
device is not ready for operation for a short time during the following start-up.
Caution!
Executing the commands Reset or Resume will clear all device buffers and Oscillo-
graphic Records. Before initial start you may want to back-up the settings and buffer
contents by means of the DIGSI Device Configuration (see Chapter 6.2, page 206).
With the bay units, the display of their input/output states or the activation/deactivation
of relays can be done via DIGSI or via the integrated operation.
In the operator tree of the bay units, under the tests, the operator addresses for the
test sequence are stated, in the block as of 4700 for the binary inputs and as of 4800
for the relay control.
For the binary inputs, the physical states are stated:
0: not activated, 1: activated.
There are two operator addresses per relay for controlling the relays
one for the activation, e.g. 4801, and one for the deactivation, e.g. 4802.
Entering the password F3F1F3F1F3F1 is required for this function.
