For DeviceNet modules, avoid selecting COS and Cyclic modes simultaneously,
as this is not allowed on DeviceNet networks.
The tree view has check mark icons beside the product names/catalog numbers and
the trigger types. The color of a check mark icon indicates the following:

I/O Setting and I/O Channel Creation
Enter the number of bytes in the Input area and Output area. This field displays
the number of bytes of I/O data available for the selected connection in the input and
output area, respectively.

Strobe - Multi-cast message starts the scan cycle. Strobe-able slaves respond,
based on their latency.
Poll - The Master queries each sensor/actuator according to the polling list.
Polls are sent out even as strobe responses are being received, as much as
bandwidth allows.
COS - A device reports its data only when there is a change. This is considered
more efficient since only data changes are transmitted. It can be used along
with Poll or Strobe.
Cyclic - Devices report data on a user-configured, time-increment basis (input
or output). Cyclic data production is considered more efficient for applications
with slowly changing analog I/O.
Green - Indicates that the complete I/O area of this specific connection has
already been assigned to I/O channels.
Orange - Indicates that some, but not all, of the I/O channels have been created.
The input and output area bytes are defined for each device in the respective
EDS files. The following are the supported standard conversion rules:
– 1 Byte to 8 Bool.
– 1 Byte to 1 DInt.
– 2 Byte to 1 DInt unsigned.
– 4 Byte to 1 DInt.
– 1 Byte to 1 DWord.
