Sizing of the group based on the amount of resources.
A CANopen header uses up to 4 messages for inputs and another 4 messages for outputs,
where each message has 64 bits available for data. The digital and analog resources of a
node must be distributed among these four messages and, also, both types of resources
cannot be mixed inside the same message. For example, a node with a RIOW-2AI-PT100
(2 x 16 bits) module and two RIOW-8DI (2 x 8 bits) modules would use two messages, even
if both have free bits available.
This means that a message can send up to 64 digital inputs or four 16-bit resolution analog
inputs. This allows for the following maximum configurations per node.
• 0 analog inputs / 256 digital inputs.
• 4 16-bit analog inputs / 192 digital inputs.
• 8 16-bit analog inputs / 128 digital inputs.
• 12 16-bit analog inputs / 64 digital inputs.
• 16 16-bit analog inputs / 0 digital inputs.
For outputs, the distribution for digital-analog resources per node is similar.
