Note:
The operating software can be updated over modem or data cable, provided Mod-
bus has been activated (CO6 > F01 - 1).
10.1 RS-232 to modem communication module
When looking onto the controller front, the connection for the optional communication mod-
ule is located on the left side of the controller housing (RJ-45 connector socket). A dial-up or
GSM modem can be connected to the controller over the RS-232 to modem communication
module (8812-2004). A dial-up modem is required if the controller is to be connected to the
telecommunications network. In this case, the controller works autonomously and can initiate
a call to the building control station when errors occur. Additionally, the building control sta-
tion can dial up to the controller, read data from it, and send new data once the valid key
number has been written to holding register no. 40145.
Note:
If a wrong key number has been written to holding register no. 40145 for the third
consecutive time, the controller immediately interrupts the modem connection and
generates an "Err 7" error message (Unauthorized access occurred). As a result, the
call to the congured control system is triggered and a text message is sent. Bit D6 is
deleted as soon as the error status register has been read by the control system and
the connection has been terminated.
In special cases, the lock dial-up function can be selected to stop dial-up in case an error oc-
curs. Using the dial-up upon corrected error function, the controller additionally informs the
building control station when a previously signaled error no longer persists.
The automatic modem conguration function causes the dial-up modem connected to the
controller to be congured automatically by the controller.
