COMMUNICATION SETTINGS. Sulzer AquaProg 6 | Manualzz

3.2 COMMUNICATION SETTINGS

AquaProg uses the following methods of communication with the substations:

- Direct connection (serial RS 232 or USB)

- Dial-up connection (modem)

- GSM and GPRS

- TCP/IP and UDP/IP (Network) for the communication with the substations.

At direct communication the substation is connected directly to anyone of the serial ports of the computer COM1 – COM32 or any of the computers USB ports.

At called connection the connected modem is used to call the substation via the telephone line.

The modem used shall be installed according to Windows standard procedure.

At TCP/IP, UDP/IP or GPRS the computer’s internal Ethernet card or Wifi is used.

In the AquaProg there is a choice between 3 different parameter settings (modem, baud rate etc.) for connection to a specific substation.

1. Standard settings.

Parameters for communication are collected from a common source which is the same for all substations which are set to use the standard settings.

This is used only if a modem, which is used to call all substations, is connected to the computer.

2. Individual settings.

All substations have their own parameters for making the connection.

The parameters are set when a new substation is created by the operator.

This type is used if several modems are connected to the computer and allows starting several AquaProg which communicate with different substations simultaneously.

A substation can also be connected via serial port while a modem is used for communication with the other substations.

3. Substation connected to AQUAVISION.

If AquaProg is used together with the alarm system AQUAVISION the parameters for connection are collected from the AquaVision system. This allows that AquaVision and

AquaProg can communicate with the same substation simultaneously.

Connection /Disconnection of substations to / from AquaVision are set when a new substation is created or when a present substation is opened.

If AquaVision and AquaProg are used on the same computer all substations should be connected to the AquaVision system, more about this later.

Always start by setting what standard settings should be valid for communication with the substations. This is best done the first time AquaProg is started.

Setting of the other types of parameter settings (individual etc..) is not described in this chapter. see chapter 4, create/open a substation.

The following pages describes how the standard settings of communication parameters are done in the AquaProg .

Choose connection in the menu field and standard settings.

The window shows following:

First choose between direct connection

(serial port), modem or network connection.

When direct connection set comport, baud rate, number of data bits and parity.

These parameters must be the same as is the substation to be connected.

To use the USB connection tic the

USB port box. To be used with ABS /

Sulzer controllers fitted with an USB port. (PC 441).

Port, Speed etc. is not relevant when using USB.

Note! If a USB to RS 232 converter is used, shall the tic box USB NOT be filled in!!!

In this case shall the corresponding Com Port number shall be set that Windows has given the unit when connected! The number given by Windows can be checked in the control panel!

When modem connection only the modem type has to be chosen, the menu gives a list of all modem types that are installed in the computer.

Chosen settings will be valid for all substations which are set to use standard for connection

When network connection is used, a selection is made for the desired protocol, TCP or UDP.

TCP is a connected protocol with build-in handling of failures (retransmission at failure etc.).

UDP is not a connected protocol and has no build-in handling of failures.

Since the network protocol only is a carrier for the application protocol, Comli/Modbus etc., is UDP the preferred network protocol. The application protocols have their own handling of failures which means that TCP only gives a unnecessary overhead.

However, there is a drawback with the UDP protocol.

When more UDP connections is connected at the same time, each UDP connection have to have a unique local port address.

With TCP, all connections can use the same local port address.

Use TCP if more substations should be connected simultaneously via the network.

As an alternative, choose "Individual setting" for the substation (see chapter 4) and set a unique local port address for each substation.

In practice is the selection of protocol to be used controlled by type of controller and type of modem connected to it.

Thereafter a local IP-address and port is chosen. AquaProg fetches the computers IP-address from

Windows, which shall be set in "Network settings" in Windows.

AquaProg supports several network cards in the computer. There is usually only one alternative to select.

Dynamic allocation of IP-addresses cannot be used with AquaProg.

"Local port" is the port where AquaProg receives incoming messages from the substation.

Port number can be set between 0 - 65535.

Port numbers below 1000 should not be used since some of these are reserved by Windows.

An exception is Modbus TCP where port number 502 normally is used.

Take into consideration that there may be firewalls etc. which blocks some port numbers and IPaddresses. Contact the network administrator for advice.

Finally choose which application protocol to use, Comli, Modbus etc.

Note! If Modbus is selected as an application protocol for network connection type TCP is the protocol Modbus TCP used as protocol!

For the other connection alternatives is Modbus RTU used!

The settings made here will be valid for all substations which are set to use default settings for connection.

It is also possible to select a station for automatic connection.

Every time when AquaProg is started will the given station be connected automatically.

Can be a useful function when to work with a certain station for a longer time period.

Just fill in the tic box ”Auto Connect” and select a station!

CHOICE OF PASSWORD

All changes, which are made in a connected substation, are protected via a password in the

AquaProg. Without the correct password nothing can be changed in a connected substation.

The first time the AquaProg is started the pass word is missing.

Here follows a description of how the password is set.

Chose “ Change pass word" in the menu “Adm”.

Following picture is shown:

The valid password has to be set if the password shall be changed.

As no password has been set this password field is left empty.

Click OK.

Following picture is shown:

Set wanted password and repeat this in the field below.

Click OK.

Do not forget to write down the password, without the correct password no changes can be made in a connected substation.

The password is selected and AquaProg will ask for this every time the first change is going to be made in a connected substation.

The operator can also log in/out manually via the menu

“Connection “ Log in /out.
