GPRS modem password

The password used by the GPRS modem for login at the server. This password

must match MODEM_PASSWORD when calling WDC_INIT in the PLC program.

This password is proposed depending on the station number but can be changed

at any time.

SPS status monitoring

Indicates if and how the connection to the PLC is monitored in periodic intervals.

• Status monitoring deactivated

The connection to the PLC is not monitored. No additional costs are created.

• Status monitoring by value updates

The connection to the PLC is monitored by updating all values from the PLC in

the configured time interval. With this option it might not be necessary to update

analogue values and counters by the PLC program in periodic intervals.

• Status monitoring by RealTimeClock synchronization

The connection to the PLC is monitored by synchronizing the PLC real time

clock in the configured interval.

Even if this option is not selected, the PLC real time clock is synchronized once

a day.

The Interval determines the frequency for status monitoring.

Notice

The status monitoring has the function to test and to indicate, if the configured

connection is still available. Often the status monitoring function is also necessary

to keep the connection alive. A lot of network operators disconnect connections

automatically if no data has been transmitted for a period of time. This can be

avoided, when frequently status requests are transmitted.

If you do not have already experiences with your GPRS service, you should

select an interval of 15 minutes and you should use Status monitoring by

RealTimeClock synchronization.

Try if the connections are stable also, if you use intervals greater than 15 minutes

and accordingly select smaller intervals if your connections are often interrupted.
