Profi Message
If a Modbus user sends values that require conversion, enable Scaling and enter
Min / Max values to convert from the Input value to the Scale value.
If the Use channel as output option is used, scaling takes place in the opposite dir-
ection: Enter the range from the source data in Scale value and the range for the
output signal in Output value .
Without scaling, the channel's Data type is used When scaling is
enabled, the floating data type is always used for the channel.
This also applies when the channel is used as an output: When scal-
ing is enabled, the channel must have the floating data type, oth-
erwise you have to use the type under
Data type .
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 num-
ber).
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 Applic-
ation enables the output value to be manually set via the DataService Configurator
or automatically set via a ProfiSignal application. The source type is converted to
the type given in
Data type (refer also to Scaling ).
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.
4.8.3.4 User-defined protocol
We recommend giving a unique Channel name , amending the Description and, if
necessary, entering a Location . The Main settings tab is described in the following
and then how input and output channels are created.
