and upload the settings into the host system as part of their Program Net. The User-
Selectable Input and Output modes are briefly described below.

Using Event/Count/Output channels as Event/Counter Inputs
When configured in HyperWare as Digital Inputs, channels I-through-P perform identically
to Channels A-through-H (described earlier in this chapter).
Using Event/Count/Output Channels as Outputs
When configured in HyperWare as a Digital Outputs, Channels I-through-P will function
as Open Collector Outputs. These Digital Outputs can be programmed to turn “on” and
“off” using HyperWare. The Digital Output of each channel is determined by program
logic and User settings within HyperWare, and uploaded as part of the Program Net.

Open Collector Outputs are a transistor switch that when ON, short the channel “+”
output terminal to the “-“ terminal. The switches are not ideal in that they do have
some resistance and current carrying limits but for most low-current signaling
applications they can be perceived as a switch.
Note that the “-“ terminal on all of the channels are interconnected.
