External Modem; Serial Port Setup Menu (9010) - Siemens SINAMICS PERFECT HARMONY GH180 Function Manual

External Modem

Overview
The NXGpro control contains a dedicated isolated RS232 port to support the use of an external
modem. The external modem allows for remote monitoring of the NXGpro drive.
Operation
The control software initializes the modem. If no call is in progress, the modem initialization
string will be sent every 30 seconds. This allows the modem to be initialized should it lose
power.
When the external modem receives a phone call it will auto negotiate the baud rate with the
calling modem and send a "RING" command to the NXGpro control. The NXGpro commands
the modem to answer the call. The calling user is then prompted to enter a user ID and
password. The password is verified against the modem password, parameter (9025). If the
password is correct, a menu based text screen is sent to the user for monitoring the drive.
The calling user can monitor drive functions from the built-in text screens. The text screens
are built into the NXGpro software so that only a terminal emulator program is required to
monitor the drive via a modem.
The modem password, parameter (9025), is located in the Serial Port Setup Menu (9010)
which is under the Communications Menu. The modem password is four characters. Each
character can be set from 0 to 9 or A to Z by scrolling through each character.
