Communication

Modem timeout (t)

When the controller connects to the GLT but without addressing a Modbus data point, the con- nection is closed after the time specified for Modem time-outhas elapsed. If the error status reg- ister has not been read during the GLT connection, the controller dials up to the GLT again after the Modem dialing pause (P) has elapsed.

Number of redialing attempts (C)

The controller tries to dial up to the control system again, observing the Modem dialing pause, in case the control station/text messaging center/fax is busy or the function that triggered the call has not been reset by the controller. After the specified number of redialing attempts have failed, the district heating controller dials up the alternative recipient.

Resetting of triggered call = Reading the error status register (HR 40060)

Phone number of control station (tELno)

Enter the phone number of the control system modem including the dialing code, if necessary. Short pauses between the numbers can be entered using P (= 1 second); the end of the string is to be marked by “–“. The phone number may include a maximum of 22 characters.

Example: “069, 2 sec. pause, 4009, 1 sec. pause, 0“:

0 6 9 P P 4 0 0 9 P 0 – (= 11 characters)

Phone number of the alternative recipient (rESno)

Enter the phone number of the alternative recipient including the dialing code, if necessary. Short pauses between the numbers can be entered using P (= 1 second); the end of the string is to be marked by “–“. The phone number may include a maximum of 22 characters.

Example: “069, 1 sec. pause, 654321“: 0 6 9 P 6 5 4 3 2 1 – (= 10 characters)
