Channel
The channel is represented by the channel type and channel number.
DARWIN has measurement channels and computation channels.
Measurement Channels
Channels whose channel type represents the subunit number of the expandable
model or the unit on the standalone model.
It is the input position identifying number that determines the module connection
position.
The channel number is created from the slot number and the terminal number.
The number may not be consecutive depending on the system configuration.
Computation Channels
The channel when the channel type is a value that represents ìcomputation.”
The computation channels can be used on models with the computation option.
On the standalone model, the channel number is an integer from 1 to 30.
On the expandable model, the channel number is an integer from 1 to 60.
Channel Type
A value used to identify the channel position and type.
For DARWIN, it is a value used to identify the channel position and type.
See Channel/Relay types.
Either the subunit number of the expandable model, the unit of the standalone
model, or computation.
Channel Number
Specified with an integer.
It is an integer value between 1 and 60.
Example: The channel number for terminal number 2 of the 10-CH, Medium-Speed
Universal Input Module in slot number 3 is 32.
For computation channels, it is an integer value between 1 and 60 on the
expandable model and 1 and 30 on the standalone model.
Channel Range
Represents the consecutive channels of the same channel type.
It is specified using the channel type, start channel number, and end channel
number.
If the end channel number is something other than the start channel number, it is
considered a single channel specified by the start channel number.
