Identification & Maintenance Data
Identification and maintenance data (I&M data) is information stored in a device. I&M data
uniquely identifies a device within a system. The identification data (I data) includes information
about the device, for example the item number and device name. Identification data cannot be
changed.
Maintenance data (M data) includes information regarding the device within the system, for
example the installation location and installation date. Maintenance data is initially stored in the
device during installation; this data can be changed.
Data Input
The Step7 software from Siemens can be used to display and change the I&M data. You can
read and write I&M data 1, 2 and 3 in the "Target System" menu of the HW Config hardware
configuration using the functions "Download Module Identification" and "Download Module
Identification to PG". see Figure 7.10 on page 54.
Tip
Replacing devices without a removable medium
Once the topology has been stored in the controller, each device within the topology can be
replaced with another device that is identical in construction. The PLC assigns this device the
device name and IP address of the replaced device.
