How to set IP address of NTP server through user program in s7-1500 CPU?“T_ The "config" instruction is used for program control configuration of s7-1500 CPU integrated PROFINET interface or CP / cm interface.
Use "t"_ The "config" command can change the Ethernet address and PROFINET device name from the user program.
Using s7-1500 CPU v1.8 and higher, and step 7 V13 Sp1 upd4 and later, you can use "t" in the user program_ The "config" command changes the IP address of the NTP server for the daily synchronization time.
Previously valid configuration data will be overridden.
You can use "t"_ The "config" command makes the following changes:
IP protocol settings
IP address
Subnet mask
Router address
PROFINET settings
PROFINET device name assignment
Clock synchronization settings
Assign IP addresses to clock synchronized NTP servers (s7-1500 only)
The corresponding configuration options can be found under IP protocol and PROFINET in the Ethernet address dialog box, or NTP mode in the clock synchronization dialog box. This is displayed in devices & Networks under PROFINET interface properties in device view and network view.
Necessary conditions for changing IP address of NTP server
To use "t"_ The "configure" command must be specified in the hardware configuration to assign IP address parameters and device names through user programs.
To do this, you need to open the properties of the PROFINET interface in the device view. In order to pass the "t"_ To change the IP address of the NTP server, you need to activate the option "start synchronization time through NTP server" in the "clock synchronization" dialog box, and then you need to specify the IP address at the NTP server.
Configuration data must be stored in the system data type and in the "conf"_ Data "parameter. In system data type if_ CONF_ NTP stores the IP address of NTP clock synchronization.
“T_ Input parameters of "config" command
Table 01 shows "t"_ Input parameters of the "config" command.

data type
describe
Req bool when req = 1, the instruction is called and starts running.
INTERFACE HW_ Interface hardware identification
The hardware identification is displayed in the interface properties in the device view and in the system constants of PLC variables.
CONF_ The pointer to the data variant advanced structure contains the system data type if_ CONF_ HEADER， IF_ CONF_ V4 and if_ CONF_ NOS (see conf_ Data parameter).
