Example 2 – Receiving Delimited Data

Using the same configuration as Example 1, the scanned UPC labels are printed in one of two
formats: [

MODEL xxx A

] and [

SN: xxxxx

]. The first format is a model number, and ‘xxx’

are 3 ASCII characters that represent a number from 1 to 100. The second format is a serial
number, and ‘xxxxx’ are 5 ASCII characters that represent a number from 1 to 60000. The
gateway is configured to read these two specific UPC label formats, convert the ASCII
characters into integers, and return them as DeviceNet inputs.

Barcode Scanner
The barcode scanner’s RS232 channel is set for 9600 bps, 8 data bits, no parity, and 1 stop bit.
When it reads a UPC label, it transmits the following ASCII message format. The message
always begins with the ASCII STX start-of-text (0x02) character, and always ends with the
ASCII ETX end-of-text (0x03) and CR carriage return (0x0D) characters. The barcode data will
consist of a variable number of ASCII characters, depending upon the UPC label being scanned.

[ STX ] [ ‘MODEL xxx A’ ] [ ETX ] [ CR ]

14 bytes ASCII data

[ STX ] [ ‘SN: xxxxx’ ] [ ETX ] [ CR ]

12 bytes ASCII data

CDN366 Gateway
The CDN366 gateway needs to be configured to receive this RS232 message format. The first
step is to determine the

Delimiter Mode

. The barcode scanner still transmits a variable length

message, so

Length Mode

cannot be used.

Timeout Mode

may be used, but without specific

timing information for the barcode scanner’s RS232 channel it may be difficult to derive a
suitable

Packet Timeout

value.

List Mode

is best suited for this application, because the serial

message always begins and ends with the same characters. The

Serial Stream Object

can now be

configured. The following shows the

Serial Stream Object

attribute settings for this application.

The 3rd column lists the address string if using Set_Attribute_Single commands to write the
attribute values. The last two attributes are Short_String data types.

12. Post-Delimiter String

0x02 0x03 0x0D

0x40 0x01 0x0C 0x02 0x03 0x0D

Short_String length = 2, ETX CR

The next step is to configure the CDN366 gateway to process the different label formats and
convert the ASCII characters into integer numbers, to be returned to the DeviceNet scanner.
With two different label formats, two Serial Receive Object Instances will be configured.
