PLC A later eﬀort to enhance the clarity of PLC programming was the concept of addressing variables in a PLC’s memory by arbitrary names rather than ﬁxed codes. The IEC 61131-3 programming standard refers to this as symbolic addressing in contrast to “direct” (channel-based) addressing, allowing programmers arbitrarily name I/O channels in ways that are meaningful to the system as a whole.
