The various kinds of data are stored in the offset positions shown in the fol-
lowing diagram, from the beginning word in the area for each Unit.

The beginning word n is calculated by the following equation:

Beginning word n = CIO 1500 + (25 x unit number)

The following items in the diagram can also be checked using software switch
settings on the CX-Programmer.

• The status of UDP/TCP sockets 1 to 8 (Opening Flag, Receiving Flag,

Sending Flag, Closing Flag, Results Storage Error Flag, Socket Open
Flag)

• Service status (FTP status)

For explanations of how to use the related communications services listed in
