GSM Radio Module CSI-F-10 Page 34
Status 29.01.2009 HYDAC ELECTRONIC GMBH Part.-Nr.: 669752
6.4 Voltage supply with communication via
direct connection to Portable Data Recorder HMG 510
If a GSM radio module is connected via a HYDAC Portable Data Recorder HMG 510 to
the PC, then the GSM radio module has the HSI address "Bus master".
If other sensors are connected to the CSI-F-10, these must be addressed using a
normal HSI address "a" or "b".
In order 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 connected sensor is to be addressed, the connection to the 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 normal HSI addresses "a" or "b".
Warning!
If the GSM radio module is directly connected to the PC and CMWIN via the HYDAC
interface module HMG 510 via HSI, no measured values are output and no new
sensors will be recognized.
In other words, if the 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.
