SINAUT MICRO SC
68 C79000-G8900-C210
Using a common mobile phone with GPRS function, please check if a GPRS
Service is available in the location of your SINAUT MD720-3.
The SINAUT MD720-3 does not reach the SINAUT MICRO SC
The SINAUT MD720-3 is attached to the GPRS, but the LED “C” is off or blinks
slowly.
If the SINAUT MD720-3 is ready for operation and the signal quality is sufficient
and the device is attached to the GPRS, please check the values for
IP_ADDRESSCS, DESTPORT_CS. DNS, MODEM_NAME und
MODEM_PASSWORD which are referred to in the PLC program module
WDC_INIT. The following values are displayed at a connected PC, when you push
the SET button (refer to System manual SINAUT MD720-3, chapter Getting the
current values and settings):
Remote-Host corresponds to IPADDRESS_CS
Destination-Port corresponds to DESTPORT_CS
Server-Username corresponds to MODEM_NAME
If the displayed values correspond to the entries of the PLC, the PLC transmits its
values to the SINAUT MD720-3 correctly. Otherwise please check the connection
between the PLC and the SINAUT MD720-3. Please compare also all values with
the corresponding parameters of the SINAUT MICRO SC.
Please check, if the SINAUT MICRO SC is reachable.
SINAUT MICRO SC is not reachable
When you have double-checked and eventually corrected all connection
Parameters of the PLC and the SINAUT MD720-3 and the connection is still not
established, eventually the SINAUT MICRO SC is not reachable.
If the SINAUT MICRO SC has already established connections to other SINAUT
MD720-3, the SINAUT MICRO SC is reachable.
If the SINAUT MICRO SC has no connection to any SINAUT MD720-3, please
check:
• that the Computer running the SINAUT MICRO SC is connected to the
Internet,
• that the server port being entered into the SINAUT MICRO SC is the same like
the value for DESTPORT_CS in the PLC program module,
• that this server port is not blocked in any hardware or software firewall,
