 Set PLC clock
This set of words, each divided into 2 bytes, tells the control system the
display-unit time at each cycle so that, if necessary, its internal real-time
clock can be updated.
The day of the week is encoded as follows:
How the various bytes are entered can be selected in the XBT L100•
configuration software: Either BCD format (in which case if it is fifteen
hours, the content of the Hour field will be 0x15) or Standard format (in
which case if it is fifteen hours, the content of the Hour field will be 0x0F)
can be selected. The choice of BCD/Standard applies to all four words,
and cannot be made independently for each byte.
