10.7 Identification and maintenance data
Procedure for reading I&M data via the user program
To read the modules' I&M data in the user program, use the RDREC instruction.
The record structure for centrally inserted modules as well as for distributed modules that are
accessible via PROFINET IO/PROFIBUS DP, is described in the chapter Record structure
for I&M data (Page 164).
Reference
The description of the instructions can be found in the STEP 7 online help.
Procedure for reading I&M data via the display
To read the I&M data "Plant designation" or "Location identifier" of the CPU via the display,
follow these steps:
1. Navigate to the "Overview/PLC" menu on the display of the CPU.
2. Select "Plant designation" or "Location identifier" and confirm with "OK".
To read the I&M data "Plant designation" or "Location identifier" of a centrally used module,
follow these steps:
1. Navigate to the "Modules" menu on the display of the CPU.
2. Select the menu command "Local modules" and confirm with "OK".
3. Select the slot of the module (e.g., slot 3: DI 32 x 24VDC HF) and confirm with "OK".
4. Select the "Status" and confirm with OK.
5. Select "Plant designation" or "Location identifier" and confirm with "OK".
To read the I&M data "Plant designation" or "Location identifier" of a module used in
distributed mode, follow these steps:
1. Navigate to the "Modules" menu on the display of the CPU.
2. Select the corresponding distributed I/O system (for example PROFINET IO system) and
confirm with "OK".
3. Select the corresponding device (for example ET 200SP-Station_1) and confirm with
"OK".
4. Select the slot of the module (e.g., slot 1: DI 16 x DC24V ST_1) and confirm with "OK".
5. Select the "Status" and confirm with OK.
6. Select "Plant designation" or "Location identifier" and confirm with "OK".
Procedure for reading I&M data via STEP 7
Requirement: There must be an online connection to the CPU/interface module.
To read I&M data using STEP 7, follow these steps:
1. In the project tree, select the CPU/interface module and go to "Online & diagnostics".
2. In the "Diagnostics" folder, select the "General" area.
