| downloading projects.All R/H CPUs have an internal clock. The clock shows: | ou can synchronize the time of the CPUs using the NTP procedureYou use your own server in your network. Your own server offers the following advantages: |
Protection against unauthorized external accesses
● Every device that you synchronize with your own NTP server uses the same time.
You want to synchronize the CPUs of your R/H redundant system with this NTP
server.
Conditions and parameters
● You have your own NTP server in your network with the IP address 192.168.1.15.
● R/H redundant system
Solution
1. Navigate to "Properties > General > PROFINET interface > Time synchronization > NTP
mode" in the properties of the first CPU.
2. For "Server 1:", enter the IP address of the NTPIdentification and maintenance data (I&M data) is information saved on the module. The data
is:
● Read-only (I data) or
● Read/write (M data)
Identification data (I&M0): Manufacturer information about the module that can only be read.
Some identification data is also printed on the housing of the module, for example article
number and serial number.
Maintenance data (I&M1, 2, 3): Plant-specific information, for example installation location.
Maintenance data for R/H is created during configuration and downloaded to the
redundant system.
R/H supports identification data I&M0 to I&M3. Exception: The synchronization
modules for H only support identification data I&M0.
The I&M identification data supports you in the following activities:
● Checking the plant configuration
● Locating hardware changes in a plant
● Correcting errors in a plant
Modules can be clearly identified online using the I&M identification data.Over the user program
● From the display of the CPUs
● Via STEP 7 or HMI devices
Reading I&M data over the user program
You have the following options for reading module I&M data in the user program:
● Using the RDREC instruction
The data record structure for centrally inserted modules and for distributed modules
accessible over PROFINET IO is described in the section Record structure for I&M data
(Page 243).
● Using the Get_IM_Data instructioThe description of the instructions can be found in the STEP 7 online help.
Reading I&M data from displays
Proceed as follows to read the I&M data of a CPU:
1. Navigate to the "Overview/PLC" menu on the display of the CPU.
2. Select "Plant designation" or "Location identifier". Click "OK" to confirm.
Reading I&M data via STEP 7
Requirement: There must be an online connection to the CPU.
Proceed as follows to read I&M data using STEP 7 from the primary and backup CPU:
1. Select the CPU in the project tree.
2. Go to "Online & diagnostics".
3. In the "Diagnostics" folder, select the "General" area.
Enter maintenance data over STEP 7
