GSM Radio Module CSI-F-10 Page 24
Status 29.01.2009 HYDAC ELECTRONIC GMBH Part.-Nr.: 669752
6.3 Voltage supply with communication via direct
connection with interface module CSI-B-2
If a GSM radio module is connected to the PC via an adaptor such as the HYDAC
interface module CSI-B-2, then the GSM radio module has the HSI address "Bus
master"
.
If further sensors are connected to the CSI-F-10, these must be addressed with the
normal HSI address "a" or "b".
In order to be able to communicate with the GSM radio module or with the sensors
connected to it, the CSI-F-10 must first be addressed using the HSI address "bus
master
". This means the GSM modem is switched into Slave mode and the PC works
as the bus master.
If afterwards a sensor connected to the CSI-F-10 is to be addressed, the connection
between PC and GSM radio module must be disconnected. In CMWIN a query
appears asking whether the master which was previously connected to the slave (the
CSI-F-10) should again be the master. This query must be answered with "No".
After this, the connection to the sensors which are connected to the CSI-F-10 can be
set up using the usual HSI addresses "a" or "b".
Warning!
If the GSM radio module is directly connected to the PC and CMWIN via the HYDAC
interface module CSI-B-2 via HSI, no measured values are output and no new sensors
will be recognized.
In other words, if a sensor had been connected to the GSM radio module before the
connection setup, only those measured values which have been output directly prior to
the connection setup appear in CMWIN.
Furthermore, new sensors must be connected to the CSI-F-10 before the connection
setup because otherwise they will not be recognized.
