IDEC SmartRelay Manual
Note
IDEC SmartRelay can recognize, read and switch the I/O of all ex-
pansion modules, regardless of their type. The I/O are presented in
the installation order of the modules.
The following I/Os and marker blocks are available for the creation
of your circuit program: I1 to I24, AI1 to AI8, Q1 to Q16, M1 to M24
and AM1 to AM6. Also available are the shift register bits S1 to S8,
4 cursor keys C

and C
, as well as 16 blank outputs
X1 to X16. More details are found in Chapter 4.1.
The following applies to the inputs I7 and I8 of FL1C-H12RCE/
FLC1-B12RCE and FL1C-H12SND versions: If Ix is used in the cir-
cuit program, this input signal is digital; signals at AIx are analog.
Input AIx can only represent the connector that is actually capable
of handling analog signals.
IDEC SmartRelay's connectors
The term connector refers to all connections and states in
IDEC SmartRelay.
The I/O status can be '0' or '1'. Status '0' means that the input
does not carry a voltage. Status '1' means that the input car-
ries voltage.
We have introduced 'hi', 'lo' and 'x' connectors to make it
easier for you to create the circuit program:
'hi' (high) is assigned the status '1',
'lo' (low) is assigned the status '0'.
You do not have to use all the of connectors of a block. The
circuit program automatically assigns the unused connec-
tors a status that ensures proper functioning of the relevant
block. If you prefer to do so, you can identify unused connec-
tors with an 'x'.
For information on the meaning of the term “block”, refer to
Chapter 3.2.
