Interface For External I/O - Siemens SINAMICS PERFECT HARMONY GH180 Function Manual

The control provides an interface to connect external analog and digital control signals to the
drive. The interface is flexible in the amount of I/O needed and provided to the system. This is
referred to as external user I/O in the software and is typically done through a WAGO configured
system.
• External digital I/O
– The external WAGO digital inputs and outputs are available to the communication
– Digital I/O is available for use with the communication networks. Refer to the NXGPro+
• External analog I/O
– Analog I/O data is used as assigned to the system through menu selection, by assigning

Interface for External I/O

The interface that connects external control signals to the drive is the WAGO I/O system. A
dedicated serial port communicates with the WAGO I/O system via Modbus protocol.
Configuring the WAGO I/O System
It is possible to customize the system per application requirements via the WAGO I/O modules
(digital in/out, analog in/out). The WAGO I/O system consists of a series of DIN rail mounted
modules that you can expand by inserting additional modules into the series of existing
modules. These are attached to the main bus coupler and always terminated on the end of the
series by a termination module. WAGO documentation details the available modules and
configuration instructions. Contact Siemens concerning which modules are supported by the
NXGpro software.
Note
Changes to the original configuration
If changes are made to the original configuration of the WAGO system in the drive system, the
SOP must be reviewed for proper assignment of I/O and function of SOP.
Grouping I/O Modules
The WAGO modules are color coded by general function as shown in the table below. When
assembling a series, like modules must be grouped together. WAGO analog modules typically
provide two input or output points but are not isolated from each other per module. Isolation
and power distribution modules assist in configuration by providing a common power rail and/

networks. The WAGO digital inputs are mapped directly to SOP flags for use within the
SOP. Digital I/O data is available and usable within the SOP (refer to Chapter Operating the
Software for further information).The SOP has predefined variable names for external
digital I/O. The SOP makes use of these I/O for whatever functionality or logic is required.

a WAGO module I/O point to a menu based analog input or output, and selecting a WAGO
analog input as an input to the drive via the associated analog input SOP flag. It is enabled
by setting the selection true in the SOP. This can be done either directly or conditionally.
