6 Communication

There are basically five different types of communication you can use to communicate with a substation. Direct (RS232 or USB), modem dial up, TCP/IP (Network) and AquaWeb-connection

Direct RS232: Connect from your computer or laptop RS232 port (or through a converter USB –

RS232) the service port in the front of the substations with is the service port. Make sure that you have same parameters for baud rate and so on in the substation as in the settings in Aquaprog.

Sometimes it’s necessary to have a check in Windows “Device Manager” to find out the settings and which comport number you have on your computer.

Direct USB: When connecting a PC 441 by a USB cable to your computer for the first time; a dialog box will appears on the computer screen for “Found new hardware”. Follow the instruction on the screen step by step. After your computer has installed the drivers for the PC 441; you will be able to communicate with the substation by Aquaprog.

Modem: This is for a “land line” / “dial-up” or GSM modem. Under all circumstances the modem has to be installed under Windows before you can use it in Aquaprog. If you don’t have a built-in modem; you must have a RS232 cable connected from your external modem to the computer. You also need a phone cable which is connected to your computer/external modem to a phone line (phone jack on the wall). The substation has to be set to “Autoanswer” to minimum 1 signal.

Network: This is used when you got a LAN modem at the substation sites and your laptop/PC is in the same local network area.

AquaWeb-connection: This can be used if your substation has an AquaWeb contract and your computer is connected to Internet.

Note When you have a modem (land line, GSM, LAN etc.) at the substation; you have to make sure that the substation communication port has same settings as the port at the modem. They must have same baud rate, same parity and same stop bit(s) and so on. If those parameters mismatch the communication will never succeeds to establish.

6.1 Communication requirements

This section describes each way to communicate to a substation and what’s requiring in those different circumstances. To be able to make any changes from the standard settings, click on Individual setting (see point

11 in picture 5.1A on page 15 in this document above).

6.1.1 Direct Communication

Make sure which comport number you are using at your computer. You find this in the Device Manager under the

Control panel – System. Ensure your settings regarding comport number, baud rate and so on. Match the setting for the comport

Crucial parameters for setup direct RS232 communication in Aquaprog (see picture5.1A on page 15 in this document above above)

1. Name of the station: Unique name for the station

3. Type of station: Use highest version type and make sure you have latest version in the substation.

5. Modbus / Comli ID: Service port in the front has always 1 which is most common.

7. Direct connection: Must be activated and the parameters must be the same as in substation. Verify comport number in the Device Manager in Windows.

10. Protocol: same as in the substation.

Necessary equipment for direct RS232 communication

Strait RS232 cable (DB9F-DB9M) from your computer to the substation service port

If you don’t have a RS232 port at your computer: use a USB-RS232 converter
