User manual

USB_ERB08 would be <IO>OOOOOOOO</IO> and the 24 port unit USB_ERB24 would

be <IO>OOOOOOOOOOOOOOOOOOOOOOOO</IO>.

The USB_SSR24 device can also have inputs. In the above example,

<IO>OOOOOOOOOOOOOOOOOOOOIIII</IO>, the last 4 terminals have been set up to

act as Inputs.

Once the IO device is configured, you can set up <Event> to listen for an input on an ‘I’ (input)

terminal or set a <Trigger> to send a message out an ‘O’ (output) terminal.

Note: all activity on the IO-contact-Closure device is logged into the operational log. If a problem

taking to the device occurs, or an error is detected in the device, the log entry should indicate this.
