COMMISSIONING

Connection to the automation system
Connect the 9-pin SUB-D plug to the MPI interface of your S7 controller.
When the ACCON-MPI-Modem 56k is connected to the PLC, the
connection to the MPI bus will be established when the initialization of
the internal modem has been successful. The Active LED should light
after a short period.
If the Power LED does not light, either the modem did not answer to the
initialization with »OK« or the ACCON-MPI-Modem 56k was not able to log
in on the MPI bus (perhaps wrong MPI address). At this time remote
maintenance is not possible.
Connection to the PC
The ACCON-MPI-Modem 56k will be connected to the PC's RS232
interface via the supplied null modem cable. So the ACCON-MPI-Modem
56k can be parametrized or used for the communication as a PC
Adapter. You can change between the different modes via the
microswitch.
Internal: Modem operating in a telephone network (microswitch
position: »Int.«)
When the micro switch is in the »Int.« position, the ACCON-MPI-Modem
56k works directly with the integrated modem. The RS232 LED is off
and the RS232 interface has no function. The access on the connected
PLC via TeleService is active.
External: RS232 direct operating at a PG/PC (microswitch position:
»Ext.«)
When the micro switch is in the »Ext.« position, the ACCON-MPI-modem
56k works with a locally connected PC Adapter or TS Adapter. The
RS232 LED is green.
Modem: Modem operating (microswitch position: »Mdm.«)
When the microswitch is in the »Mdm.« position, the ACCON-MPI-
Modem 56k works as an external analog modem. The RS232 LED is red.
