DBM-6000 : Protocol Converter for the MAYLIS BUS (Castel)

This protocol has been validated on a DBM-6000 ARM controller with an IP protocol converter. Interfacing has been developed with two Maylis units 101194 1189-V2.4.1 and one 440.2000-1 ind.D

All the intercoms and calls status can be monitored. There is no possibility for the DBM-6000 to modify any parameter of the Maylis system.

To interface a Maylis network to the DBM-6000, one Protocol Converter and one Maylis rs-232 serial interface are needed.

A protocol converter can monitor up to 2000 points. This capacity is limited by the number of DinCool channels in the controller.

In the installation window, let us say that each item is a node.

1) How to set up the system:

Add a protocol converter on the controller.
In the window “management of the devices on the main bus”, control that the model is "MAYLIS 6000" and the version is "3.30". If it is not the case, then burn the converter flash with the file named MAYLIS_IP.S24 .
Add a single slave on the converter: the Maylis Interface.
Add the messages sets. Each message is related to a particular intercom. See below for details.
Add detectors in these messages.
TIPS:
- To set up the system quickly and in a safe way, start with one intercom, set it up completely and verify its correct function. For the following intercoms, use all possibilities of COPY/INSERT and COPY/PASTE on whole messages : it will create all the detectors for you.
- To control and rename variables quickly, use the 'list variables' options from the protocol converter or the Maylis icon sub-menu.

2) Configuration of the Converter node:

Name	Maylis Converter	mandatory: a name to identify the protocol converter
Address	xxxx	mandatory: the serial number labelled on the protocol converter.
Protocol	Alarm Central	mandatory
Bauds	9600	mandatory
Bits	8	mandatory
Parity	None	mandatory
Number Retry	-	This is the number of times the message is repeated before the converter generates a fault on the bus. Not use here.
Rx Time out	-	This is the time interval before repeating a message not acknowledged. Not use here.
Rx Time Ready	-	This is the delay before sending the next message after an acknowledge. Not use here.

3) Configuration of the Interface node:

The Maylis rs-232 serial interface is a slave for the protocol converter.

Name	A denomination for the Maylis interface
Address	0
*Survey this connection*	Should be checked, or no alarm bus error will be generated.

4) Configuration of the Messages node:

A message is an intercom. You can give a name at your convenience but the address must be the correct Maylis logical address.

*Name*	The intercom name
*Address*	The Maylis logical address of the intercom

5) Configuration of the Variables:

In the DBM-6000, a tag is referred as a detector. The tag with address 0 is for any of the 4 kinds of call programmed on the buttons of the intercom. Following addresses can be used to filter any special call type. See table below for calls type.

TIP: When using address 0 you will be sure to always see all the calls from the intercom.

When you create the detector (an Maylis kind of call), this configuration popup is automatically displayed.

Later, when editing the channel properties, go in the installator sheet and click on 'input properties' or select the variable in the variable list of the Maylis node.

As for any other DinCool channel, you can set alarms. In case of alarm, it is immediate in case of a Maylis level 10 priority or timed in case of a Maylis level 9 priority.

Name

the tag name

Address

0: for any kind of call

1: for direct call only

2: for grouped call only

3: for multiple call only

4: for general call only

5.1 Channel properties:

States 0 to 8 are meaningful. Set the text as shown in the figure.

For a maylis priority less than 7, the state is the priority.

For priorities values of 7 and 8, the state is 7 and for priorities values of 9 and 10, the state is 8

Default state is '-' (priority 0).

In case of detection, the status changes immediately and remains 5 seconds before going back to default.

The alarm time-out (Temporisation) can be set to a value greater than 5 seconds to prevent that kind of alarm (Priority 9).

5.2 The default plan images :

	Not known
	Idle

For other parameter's value, choose from the colored icons list at your best convenience.

6) Accessing variables with DinTalk:

Add an external variable of type integer. Select the wanted channel in the list.

Possible integer values are 0 to 8 depending on the tag status.

7) Connection control:

Don't forget to set the 'Alarm on device offline' in the controllers properties.

If the protocol converter is disconnected, the converter detects the absence of communication and an error bus is generated immediately. The alarm programmed for main bus errors (if any) in the controller is started.

If the Maylis RS-232 module is disconnected from the converter, the converter detects the absence of communication and an error bus is generated. The alarm programmed for main bus errors (if any) in the controller is started.

If the Maylis RS-232 module is disconnected from the Maylis bus, the converter detects the absence of communication and an error bus is generated. The alarm programmed for main bus errors (if any) in the controller is started.

8) Cabling RS-232

Wiring : RS-232 cable: 3 wires

Protocol converter (Modbus port)	Sub D9 femeale
RX (IN1)	3 (TX)
TX (IN2)	2 (RX)
GND	5 (GND)
	4 (DTR) shunted to 8 (CTS)
