3-2 Allocated CIO Area Words

Data is stored at the offset positions shown in the figure below starting from the first word allocated to the Unit in the CIO Area.

The first word can be calculated as follows from the unit number setting:

First word n = CIO 1,500 + (25 x unit number)

3-2-1 Software Switches 1 (Word n)

All switches execute some function when the user turns them ON. They turn OFF automatically after the function has been executed. Once a function is set by turning a switch ON (except for the switches listed below), it is saved regardless of whether the power is turned OFF and ON again.

•Remote I/O Communications Start Switch (bit 02, 03)

•Remote I/O Communications Stop Switch (bit 04)

Note No functions other than master and slave communications are disabled by stopping master or slave communications.

If multiple bits are turned ON simultaneously, the requests will generate errors but they will not alter Unit operation. The corresponding error bits in the follow- ing words will turn ON if a request made by a software switch ends in an error.
