For 42IO version, the type of these I/Os are 8 channels configurable digital inputs/outputs on section E, and 2 channels analog inputs
plus 4 channels fast digital / 32-bit counter inputs on section F.
Each channel of Configurable digital I/Os can be configured as digital input or digital output through web-based configurator and/or
WorkSuite configuration (details are provided in RTU User Guides).

For 42IO version, pin assignment of the expanded I/Os (on section E and section F connectors) are described in the following tables:

Com2,3 Common for digital/counter input channels 2 & 3
Characteristics and wiring diagrams for all digital and analog I/O channels of the expanded IOs are the same as the other I/Os described
before. Digital/counter inputs group 1 (CI0 and CI1) and digital/counter inputs group 2 (CI2 and CI3) are electrically isolated from each
other (equipped with optocouplers with separated commons for each group).
Note 1: Common or negative pin of Configurable digital I/Os on section E of expanded IOs ( - or C ) is NOT internally connected to the
common or minus of the other sections.
Note 2: Commons for Digital/counter input channels ( Com0,1 and Com2,3 ) are NOT internally connected. It means that they must be
connected to “minus” separately. In other words, if COM0,1 is connected to the minus and COM2,3 is not connected, only CI0 and CI1
will work according to their applied signals, and CI2 and CI3 will not work.
