Revision 1.0
• 10 is the start address of the analog outputs
• 0 is the number of analog outputs
Depending on the actual GRT1-ML2 configurations, gaps are introduced in
the available digital I/O ranges. In the example above, the range of
distributed digital inputs and outputs is [32–127], but there are gaps in the
digital inputs in the ranges [40–95] and [108–127], and there are gaps in the
digital outputs in the ranges [32–63], [80–95] and [104–127]. These digital
inputs and outputs are virtual. Virtual digital inputs always have value 0
(OFF). Virtual outputs can be set ON or OFF and they can be used in
programming, but they do not have a physical representation and cannot
activate a device.
