Module ID
A drive unit can be represented by a slot model. The slot model of the CU240S PN provides
modules and sub-modules. The module-ID is the ID of a slot module or slot sub-module in
this model.
The module ID has four digits and is assigned by the system. The slot model of the CU240S
PN provides two main module ID:
● Module ID of slot 0, device access point (DAP)
This module ID is used as a representative of the device. This module ID does not
provide access to the drive parameters.
● Module ID of slot 1, parameter access point (PAP)
This module ID provides access to the following:
– All drive parameters via the parameter access point
– The cyclic data via defined telegrams
Device name
At delivery state, an IO device does not have a device name. You assign a device name with
the IO supervisor. Then, the IO device can be addressed by an IO controller. The device
name is used to transfer of project engineering data (including the IP address) during
startup.
Note
The device name must be saved in a non-volatile fashion either using the Primary Setup
Tool (PST) or using HW Config from STEP 7.
Device-ID
Each PROFINET device has a specific device ID that is issued by device manufacturer. The
device ID provides replacing an IO device without configuring in STEP 7.
The device-ID for SINAMICS G120 indicates the following table:
Vendor ID
Device ID
Class of device
Device familiy
002A
05
02
(=Siemens AG)
(=Drives)
(=SINAMICS G120)
Replacing Control Unit CU240S PN (IO Device)
If the IP address and device name are stored in a non-volatile memory, this data are also
forwarded by the Micro Memory Card (MMC) of the Control Unit.
If an IO device must be completely replaced due to a device or sub-module defect, the
Control Unit automatically assigns parameters and configures the new device or sub-
module. Following this, cyclic exchange of use data is restarted. The MMC allows module
exchange without an IO supervisor when a fault occurs in a PROFINET device.
