Chapter Ⅲ General Descriptions for Function Blocks
FAB series products adopt the programming method by the use of twenty kinds of
FBs (function blocks), each of which is able to independently implement a specic
controlling function like time-delay On, time-delay Off, Switch time setting and
counting. If several FBs are linked together, then complicated controlling func-
tions can be implemented. Contrasted with the traditional PLC instruction pro-
gramming, FAB’s FB programming is much easier and simpler.
The following types of editing operands for FBs are available for options:
1. Options of input ports: I1 - IC (Input ports), Q1 ~ Q8 (output ports), Moo-M126
(middle relay), HI (High potential status), LO (Low potential status), X (no input
connection), P0 - P9 (Telephone two-tone pulse)
2. Options for output ports: Q1 ~ Q8 (output ports), M00~M126 (intermediate re-
lays).
