The IOS Variable
The IOS variable has three parameters when used to configure the isolated digital I/O. These are:
1] I/O Line Type: Specifies the the type of I/O that the line or group will be configured
as, i.e. general purpose or dedicated function.
2] I/O Line Function: Either an input or an output.
3] Active State: Specifies whether or not the line will be active HIGH or active LOW.
The default configuration of the standard I/O set is: 0,0,1. This means that by default each line in group 20 is
configured to be a General Purpose (0), Input (0), which is active when HIGH (1). The following figure and
exercises illustrate possible configurations of the IOS.
NOTE: When configuring a dedicated input or output, the
second parameter of the IOS Variable MUST match the func-
tion, either input or output, or an error will occur.
