8.3 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
controller 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
con- trol system/the text messaging center to avoid a permanent overloading of
the telecom- munications 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 con- nection, 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 at- tempts have failed, “OFF“ is indicated in the controller's
extended information level. The dialing attempt counter is automatically reset at
12:00h and the controller tries to con- nect again. Resetting of triggered call =

Enter the phone number of the control system modem including the dialing code, if
nec- essary. 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“:
