Description of communication parameter settings

Station address (ST)
This address is used to identify the controller in bus or modem mode. In a system, each control-
ler needs to be assigned a unique address.
Modem dialing pause (P)
It is recommendable to pause for approx. 3 to 5 minutes between dialing up to the control sys-
tem/the text messaging center to avoid a permanent overloading of the telecommunications
network. The Modem dialing pause defines the interval between 2 dialing attempts.
Modem time-out (T)
When the controller connects to the control station (GLT) but without addressing a Modbus data
point, the connection is terminated after the time specified for Modem time-out has elapsed. If
the error status register has not been read during the GLT connection, the controller dials up the
GLT again after the Modem dialing pause (P) has elapsed.
When sending a text message, the specified time is without meaning.
Number of redialing attempts (C)
The controller tries to dial up to the control system again, observing the Modem dialing pause ,
in case the GLT/text messaging center 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, "OFF" is in-
dicated in the controller's extended information level. The dialing attempt counter is automati-
cally reset at 12:00h and the controller tries to connect again.
Resetting of triggered call = Reading the error status registers (HR40150)
Phone number of control station (TELnr)
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)
Note: The connected modem is automatically configured when the function block
CO6 -> F04 - 1 is activated.
