IDEC SmartRelay software
IDEC SmartRelay Manual 254
Note
Please note that the SmartRelay ladder programming is slightly dif-
ferent from PLC programming.In the case of a PLC, the output re-
sult on each line is reflected on the inputs within the same scan
time. However, in the case of the IDEC SmartRelay, all the inputs
are processed first and then the outputs. Thus the output results are
not reflected on the inputs within the same scan time, but rather
they are reflected at the following scan.
ex) Interlock is not activated in the sample program (1) below in
which input terminals I1 and I2 are simultaneously turned on. The
interlock is activated in the sample program (2) below in which input
terminals I1 and I2 are simultaneously turned on.
