DBM-6000 : Protocol Converter for the EPC444 ESPA standard

This protocol has been validated on a DBM-6000 ARM controller (DBM-6130) with an RS protocol converter (DBM-5236).

There is no need to define slave, messages and detectors like in other protocol converters. The only use of this protocol converter is to print a formatted string witch will be transmitted using the EPC444 standard.

1) How to set up the system
2) Configuration of the Converter node
3) Accessing with DinTalk
4) Cabling RS-232

1) How to set up the system:

Add a protocol converter on the controller.
In the window “Burn the devices” (open it by right click on the controller), check that the model is "EPC444/6000" and the version is "3.30". If it is not the case, then burn the converter flash with the file named ESPAR_RS.S24 .

2) Configuration of the Converter node:

Name	EPC444 Converter	mandatory: a name to identify the protocol converter
Address	xxxx	mandatory: the serial number labelled on the protocol converter.
Protocol	Auto	Leave default
Bauds	9600	Mandatory: depends on equipment connected
Bits	8	Mandatory: depends on equipment connected
Parity	None	Mandatory: depends on equipment connected
Number Retry	-	This is the number of times the message is repeated. Default is 3.
T1	-	This is the time interval before repeating a message not acknowledged. Must be set.
T2	-	Not used here.

3) Accessing with DinTalk:

Message can be sent to an ESPA compatible device using a PRINT command in DinTalk, the parameter after the logical address of the protocol converter is a string which must be right formatted.

example of code:

Print 6 : "123456;Hello world !;0"

detail of the print:

6 is the logical address of the converter, must be changed to yours

the string can contains up to 3 parts, separated by a semicolon.

123456 is the call number of the equipment (max 16 characters)

Hello world ! is the text to send (max 40 characters)

0 is the beep coding (number from 0 to 9)

The first two should be presents, the third is optional

In case of a NACK received from connected device, message will be re-sent as defined in step 2.

4) Cabling RS-232

Wiring : RS-232 cable: 3 wires

Protocol converter (Modbus port)	DB-9
RX	2 (RD)
TX	3 (TD)
GND	5 (GND)
