Scaling example
In the above image, a conversion takes place from 2000 (integer value) to
200 (°C), i.e. it returns a decimal point despite transmission of an integer
(whole number).
Using the channel as output
If you create a Modbus channel as an output, you can send data from the
Delphin
device to other Modbus users.
Enter the data for the message to be sent in a similar way to a Modbus
input. You must also enter the
Source
(of the signal).
Enter either a constant for the
Source
(
Manual value
) or select
Channel
and an existing channel in the device for which a value is to be output.
Selecting
Application
enables the output value to be manually set via the
DataService Configurator or automatically set via a
ProfiSignal
applic-
ation. The source type is converted to the type given in
Data type
(refer
).
Inherit status
(for Channel settings only): The status of the input channel
is used, but not output to the CAN bus.
Set asynchronous
: When this option is enabled the output value transmits
as soon as the value changes, that is, in real-time. Otherwise a new value
is transmitted with the next cycle.

CAN connection
Follow these steps to run a device or sensor via the CAN interface (both the
reading and output of signals is possible):
1. Configuring the basic settings of the CAN connection (this section)
2. Creating the channel for CAN protocol:
The CAN connection is displayed in the
Channels
tab with the CAN-symbol
. The CAN connection is available in the user-defined channel view
under the interface entry. The hardware channel view lists the CAN con-
nection directly below the device as long as the user has not already
moved the modules or channels.
Double-click a CAN entry or select
Properties
from the context menu to dis-
play the configuration dialogue. Set the baud rate and the length of the
identifier in the Main settings tab. We recommend giving a unique
Channel
name
, amending the
Description
and, if necessary, entering a
Location
.
