Engineering mode
Engineering mode is used for configuring the
AS-Interface
®
circuit.
To set RA-IN into engineering mode, press the Mode key for at
least five seconds. In engineering mode the yellow LED prj mode is
lit.
On the digital display, all AS-Interface
®
slaves detected by RA-IN
are displayed in ascending order at 0.5 second intervals, starting
with the A slaves before the B slaves. blank display indicates that
no slave have been detected in the AS-Interface
®
circuit.
In engineering mode, all detected slaves except for slave 0 are
activated. RA-IN is in normal mode. The data exchange on AS-
Interface
®
takes place between the RA-IN and all detected AS-
Interface
®
slaves, regardless of whether or not the latter have
already been configured.
Protected operation mode
Selecting protected operation mode
To exit engineering mode, press the Mode key.
Press key briefly:
RA-IN changes from engineering mode into protected operation
mode without configuring the current actual configuration as
target configuration.
Press key for more than 5 s:
RA-IN changes from engineering mode to protected operation
mode. At the same time the actual configuration is saved to
EEPROM as target configuration.
In protected operation mode only those AS-Interface
®
slaves that
have been configured and whose target configuration corresponds
with the actual configuration are activated.
Configuration errors in protected operation mode
If no configuration errors are detected, the digital display is
switched off in protected operation mode. Otherwise the address
at which an incorrect assignment has been detected is shown. An
incorrect assignment means that a slave has been detected or
configured but can not be activated.
If more than one incorrect assignment is recognized, the one that
was identified first is also displayed first. To view the next highest
incorrectly assigned address on the digital display, press the Set
key.
Intermittent configuration errors are saved in the device (extended
AS-Interface
®
diagnostics). To view the most recent intermittent
configuration error, press the Set key. If the configuration error
was caused by an intermittent AS-Interface
®
power supply failure,
a “39” is displayed in this position.
Addressing AS-Interface
®
slaves in engineering mode
AS-Interface
®
slave addresses can be assigned with an addressing
device.
Alternatively you can conveniently commission AS-Interface
®
with
the operating software AS-i Control Tools from Bihl und
Wiedemann.
If there are no aids available, such as a PC or addressing unit, then
the addresses can also be input directly on the AS-Interface
®
-slave
devices by means of the pushbuttons. The procedure for this
method is described below.
AS-Interface
®
slave addressing
(assigning an available address to a slave with address 0)
In engineering mode, the addresses of all detected slaves are
displayed. To view the next highest unassigned address, briefly
press the Set key. To view further unassigned addresses, continue
to press the Set key briefly.
To select the currently displayed address as target address, press
the Set key for more than five seconds. The displayed address then
flashes on the display. RA-IN is in programming mode; to assign
the flashing address to a connected slave with address 0, press the
Set key again.
If an error occurs, the corresponding error code appears (see
section “Digital display”, page 32 for explanation of error codes).
Otherwise any further unaddressed slaves are displayed in turn, as
described under section “Engineering mode”, page 30.
h
Caution!
In engineering mode, all detected
slaves are activated even if there are differences between
the target
and actual configuration.
h
Caution!
By default, new RA-IN units are supplied with engineering
mode selected.
h
Unlike in engineering mode, data exchange protected
operation mode takes place only between RA-IN and the
configured AS-Interface
®
slaves.
h
If a slave with address 0 is detected on the AS-Interface
®
,
engineering mode can not be exited!
h
Caution!
The AS-Interface
®
circuit must never contain more than
one slave with the same AS-Interface
®
address.
