Communication module KOM232M
The connector for the
optional
communication module (Mat-No. 11988) is located on
the left side (front panel view) inside the controller housing (RJ45 connector). The
communication module KOM232M allows the connection of a dial up modem to the
controller.
A dial up modem is required when connecting the controller to the telecommunication
network. This way, the controller operates autonomously and is enabled to send a call to
the building control system (BCS) in case of failures. Additionally, the BCS can call the
controller to read it out and to send new data providing the valid access code after
having written the holding register No. 40145.
Note: Once the holding register No. 40145 has been written for three consecutive times
accessed with an invalid code, the controller cuts the modem connection immediately
and generates an error message "Err 7" (Unauthorized access). Therewith a call to the
configured control system as well as an SMS delivery are triggered. Bit D6 is deleted
as soon as the error status register is read out by the control system and the
connection is terminated.
T
he function
modem dial up blocking
can be selected in special cases in order to
suppress dial ups to report failures. With the function
modem dial up on corrected
failures
the BCS is additionally informed if a previously reported failure no longer exists.
By using the
automatic modem configuration function, the modem connected to the
controller needs no further configuration; this is done automatically by the controller.
