Please note that the SmartRelay (FL1C) ladder programming is slightly different from PLC programming. In the case of a PLC, the output result on each line is reflected on the inputs within the same scan time. However, in the case of the IDEC SmartRelay (FL1C), 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 reflect at the following scan.
