IFE/EIFE Interface Generic Commands

Get Current Time

The get current time command is not hardware protected. The get current time command is still enabled when the locking pad located on the front panel on the IFE/EIFE interface is in locked position.

To get the current time for all modules, set the command registers in the following way:

Address	Register	Unit	Type	Range	Description
0x1F3F	8000	–	INT16U	768	Command code = 768
0x1F40	8001	–	INT16U	10	Number of parameters (bytes) = 10
0x1F41	8002	–	INT16U	8704	Destination = 8704 (0x2200)
0x1F42	8003	–	INT16U	0	Security type of the command
0x1F43–0x1F44	8004–8005	–	OCTET STRING	0	Password of the command = 0 (no password required)

The following registers contain the time data:

Set Absolute Time

The set absolute time command is still enabled when the locking pad located on the front panel on the IFE/EIFE interface is in locked position.

To set the absolute time for all the IMU modules, set the command registers in the following way:

Address	Register	Unit	Type	Range	Description
0x1F3F	8000	–	INT16U	769	Command code = 769
0x1F40	8001	–	INT16U	18	Number of parameters (bytes) = 18
0x1F41	8002	–	INT16U	8704	Destination = 8704 (0x2200)
0x1F42	8003	–	INT16U	0	Security type of the command
0x1F43–0x1F44	8004–8005	–	OCTET STRING	0	Password of the command = 0 (no password required)
0x1F45-0x1F48	8006–8009	–	XDATE	–	Current date/time

NOTE: Date and time counter is reset and will restart at January 1, 2000 when the internal battery of the MicroLogic X control unit is removed, if the control unit has no other power supply.

NOTE: If the IFE/EIFE interface is not configured in SNTP mode it is mandatory to set absolute time for all the IMU modules periodically, due to the clock drift of each IMU module. Recommended period is at least every 15 minutes.

Write User Application Name

The user application name can be read from registers 10242 to 10273 IMU Identification.

To write the user application name, set the command registers the following way:

Address	Register	Unit	Type	Range	Description
0x1F3F	8000	–	INT16U	1032	Command code = 1032
0x1F40	8001	–	INT16U	–	Number of parameters (bytes) = depends on the length of the user application name (up to 46 characters)
0x1F41	8002	–	INT16U	0	Destination = 0 (0x0000)
0x1F42	8003	–	INT16U	0	Security type of the command
0x1F43–0x1F44	8004–8005	–	OCTET STRING	0	Password of the command = 0 (no password required)
0x1F45–0x1F46	8006–8007	–	INT32U	–	17039366 = User application name (load 0x0104 into register 8006, 0x0081 into 8007)
0x1F46	8008	–	INT16U	2048	2048
0x1F48	8009	–	OCTET STRING	–	MSB = First character of the user application name LSB = Second character of the user application name
0x1F49–0x1F5F	8010–8038	–	OCTET STRING	–	Depends on the length of the user application name and ends by the NULL character 0x00

Set Validity Duration of Data

This command allows to set the validity duration of data in the standard and legacy datasets.

The validity duration of data can be read in a register Validity Duration of Data.

To set the validity duration of data, set the command registers in the following way:

Address	Register	Unit	Type	Range	Description
0x1F3F	8000	–	INT16U	41868	Command code = 41868
0x1F40	8001	–	INT16U	12	Number of parameters (bytes) = 12
0x1F41	8002	–	INT16U	8705	Destination = 8705 (0x2201)
0x1F42	8003	–	INT16U	1	Security type of the command
0x1F43–0x1F44	8004–8005	–	OCTET STRING	–	Password of the command: Administrator, Services, Engineer, or Operator user profile password
0x1F45	8006	s	INT16U	5–300 (in step of 5 s)	Validity duration of data Factory setting: 10 s
