Function Of "P-Digital Outputs; Function Of "P-Analog Outputs; Operation Of Several Inverters On One Pc - Siemens SINAMICS G180 Installation And Operating Instructions Manual

8.1.12

Function of "P-DIGITAL OUTPUTS"

The inverter provides at least four relays and two LEDs. In the "P-DIGITAL OUTPUTS"
menu, you can select the signal which should actuate the respective relay or LED from a list
("Bitpool"). More outputs might be available depending on the variants and quantity of
installed power sections.
8.1.13

Function of "P-ANALOG OUTPUTS"

The inverter has two electrically isolated analog outputs. Depending on the type of
connected measuring instrument, the output signal is automatically set to a +20 mA current
source or to a +10 V voltage source. Input the following in the "P-ANALOG OUTPUTS"
menu:
● Which signals should be output?
● What is the full scale value of your display instrument?
● Should a 4 mA addition or a different value be added?
● Should a center point increase be output for the presentation of bipolar signals?
8.1.14

Operation of several inverters on one PC

It is possible to operate several inverters simultaneously with one PC using the PC tool
"IMS". This is either possible via the serial interface RS 485, the optional fieldbus interfaces
PROFIBUS or PROFINET.
● For RS 485:
you require an appropriate interface converter from Ethernet or USB to RS 485, and you
must establish an RS 485 bus connection between the relevant converters (-X51) and the
interface converter. You must set the baud rate for all devices to the same value, and the
participant address of the converter to different values ≥ 3.
You must be able to access the interface converter via the Ethernet network or it must be
connected to the PC via USB.
● For PROFIBUS:
you require the appropriate interface converter from Ethernet or USB to PROFIBUS
(manufacturer: Softing) and you must connect this with the relevant PROFIBUS line. You
must set your control system for this PROFIBUS line so that you accept an additional
Class 2 master in the communication.
When establishing the connection, the interface converter must be set to a free bus
address and the given baud rate.
● For PROFINET:
you must establish a PROFINET bus connection between the relevant converters (via
port 1 or port 2 of the PROFINET board) and the Ethernet interface of the PC. All
participants must have a unique IP address and be located in the identical subnet.
