Profi Message
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 CAN bus channel as an output, you can send data from the device to
other CAN bus users.
Enter the data for the message to be sent in a similar way to a CAN bus input.
There is no
mask avaialble here as for an input, so the (signal) source has to be
entered.
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.

COM connection
Follow these steps to run a device via the COM interface (serial, Modbus RTU or
PROFIBUS):
l
Select the interface mode of the COM connection (this section).
l
Set the communication parameters for the selected COM connection.
To use the connection for PROFIBUS, the following settings must be adopted:
l
Configure the PROFIBUS protocol .
l
Create one (or several) channels: PROFIBUS channel .
To use the Modbus RTU connection, the following settings must be adopted:
l
Configure the Modbus RTU protocol .
l
Create a Modbus RTU master or a Modbus RTU slave .
l
Create one (or several) channels: Modbus channel .
Alternatively, you can set a protocol yourself - the user-defined protocol:
l
Configure the user-defined protocol .
l
Create one (or several) input channels .
l
Create one (or several) output channels .
To use the connection as a logger for PROFIBUS data telegrams, the following set-
tings must be adopted:
l
Configure the PROFIBUS logger protocol .
l
Create one (or several) PROFIBUS logger pairs .
l
Create one (or several) input channels .
