IDEC SmartRelay functions
IDEC SmartRelay Manual 111
There are also 16 blank outputs available. These are
identified with an x and cannot be reused in a circuit program
(in contrast to memory markers, for example). The list shows
all programmed blank outputs, and one blank output which
is not yet configured. A blank output, for example, is useful
for the special function ”Message texts” (see Chapter
4.4.23), if only the message text is of significan
ce to
a circuit
program.
2) Analog outputs
Analog outputs are identified by the letters AQ. Two analog
o
utputs are available, namely AQ1 and AQ2. An analog
output can only be connected with the analog input of a
function, an analog memory marker AM or an analog output
connector.
The following figure shows an example IDEC SmartRelay
configu
rat
ion and the numbering of the inputs and outputs
for the circuit program.

Memory Markers
Memory Markers are identified by the letters M or AM . These are
virtual outputs, which output the value of their inputs. IDEC Smart-
Relay provides 27 digital memory markers M1 ... M27 and 6 analog
memory markers AM1 ... AM6.
Startup Marker
Marker M8 is set in the first cycle of the user program and
can thus be used in
your circuit program as a startup marker.
This signal is automatically reset after the circuit program
has completed its first cycle.
The M8 marker can be used in all further cycles for setting,
de
letion and evalu
ation procedures in the same way as other
markers.
