According to the SOHO EID A (25-Mar-1991), section 3, page 87, the OBDH Block Command Structure consists of one 16 bit header word (ML-A) and between 1 and 31 16 bit data words (ML-B1 ... ML-B31). The last ML-B word always contains a checksum value of all the ML-A and ML-B words preceding the checksum word.
MSB LSB
header word ML-A
data ML-B1
data ML-B2
data ML-B3
data ML-B4
: :
data ML-Bn-2
data ML-Bn-1
checksum word ML-Bn 1þnþ31
The ML-A word consists of the following fields:
MSB LSB
15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0
res'd Destination Command Block Length
Address Identifier
The two most significant bits are reserved and are set to zero. SUMER's destination address is 11. The command identifier will be 8 for all telecommands of the SUMER Instrument Software except for the spacecraft interface handler telecommands. The block length field indicates the number of ML-B words including the checksum word. No ML-B words except the checksum word are required.
The SUMER Instrument Software uses the ML-B1 word to identify the telecommand (TC) to be executed. The other ML-B words contain the parameters of the telecommand, if any, and the checksum value. Thus, a SUMER telecommand consists of six bytes (ML-A, ML-B1, checksum) and two or four bytes per parameter.
The SUMER ML-B1-Word consists of the following fields:
MSB LSB 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 Command Type Identifier Sub-Command Identifier
The command type identifier can contain one of the following values:
B0 Command Dispatcher Telecommands
B1 Parameter Telecommands
B2 Command List Handling Telecommands
B3 Direct Telecommands
45 Level 3 Function
46 Level 4 Function
The following table associates the command type identifiers (cti) and the sub-command identifiers (sci) in hexadecimal notation for these telecommands and L3/L4 functions.

The following sections list the telecommands defined to control the SUMER DPU. To facilitate the finding of telecommands in these sections, the listings employ a tabular format as explained in the following example.
MLB hex command specifier
1 BA98 command specifier 2 uuuu select 0 - 0xFFFF 3 cccc checksum
Comment on the command or on parameters of the command.
The tabular format used to list the telecommands consists of three blocks of one or more lines:
1. The first block gives the column headers for the second line block ("MLB hex") and states the name of the telecommand. This first line block is separated from the rest of the command by a dividing line to facilitate the finding of telecommands.
2. The second line block (just below the dividing line) is built using another tabular format that consists of three columns:
2.1. In the first column, the number of the respective MLB word is given. Whenever the MLB word count in a telecommand cannot be known in advance, i.e. for all commands of variable length, the last MLB word is indicated by noting 'n', the last but one is indicated by noting 'n-1', etc.
2.2. In the second column, all values that are known in advance are given in hexadecimal notation (i.e. using the decimal digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, and the uppercase letters A, B, C, D, E, F. All values that cannot be known in advance, i.e. all parameter values, are indicated by parameter codes using the decimal digit 0, the lowercase letters, and the uppercase letters R, U, and X.
2.3. In the third column, short descriptions of the values or parameters are given. Whenever possible, the allowable range of values is listed. In case no range is mentioned explicitly, the parameter code (see below) in the second column provides an indication of the maximum possible range. This, however, does not mean that every value in that range could be used.
3. The third block of lines provides a short description of the command. In addition, it is used to list miscellaneous pieces of information, e.g. parameter values, notes, cautions.
MLB words consist of 16 bits. Depending on the data types of the parameters to be transmitted, these 16 bits are used to represent signed or unsigned integers:
ssss signed integer, maximum range: -32768 to +32767 (0x8000 to 0x7FFF)
uuuu unsigned integer, maximum range: 0 to 65535 (0x0000 to 0xFFFF)
00uu unsigned integer, maximum range: 0 to 255 (0x0000 to 0x00FF)
xxxx 16 bit parameter of unknown type
cccc checksum: unsigned integer, maximum range: 0x0000 to 0xFFFF
zzzz checksum: unsigned integer, maximum range: 0x0000 to 0xFFFF
(used in case where two different checksums have to be transmitted)
MLB words consist of 16 bits. Whenever values of 32 bits length (e.g. 32 bit real numbers) have to be transmitted, two consecutive MLB words are used.
The first word contains the least significant 16 bits (indicated by lowercase letters "rrrr-"), the second word contains the most significant 16 bits (uppercase letters "-RRRR". To visually connect such consecutive MLB words and to indicate their special properties, the first word of such a pair is marked with a trailing dash ('-'), while the second word is marked with a leading dash:
rrrr-
-RRRR real number in 32 bit representation (ANSI-IEEE Standard 754-1985)
uuuu-
-UUUU 32 bit parameter of type unsigned integer
xxxx-
-XXXX 32 bit parameter of any unknown type (signed, unsigned, or real)
MLB words consist of 16 bits. Whenever user defined programs in token code form (tokens consist of 8 bits) have to be transmitted, a single MLB word is used to contain two separate tokens.
TtTt two separate tokens contained in a single MLB word
These telecommands are handled by the spacecraft interface handler process directly. Except the WAX pulse command, they will not be transferred to the telecommand dispatcher in a higher level.

When switching off the power supply via SUMER 4 of an MC, the user is responsible that the specified MC is not used for measuring the temperature for the heater control.
Bit 65: Enable Moving Of 2 MCs If this bit is set to 1, two MCs can be moved at the same time (level 3 functions point, lambda1x, spectrohelio2). If this bit is set to 0, the motions are performed sequentially.
Bit 66: Only +18V or -18V available Setting this bit to 0 signals that +18V and -18V are available from SUMER 4. If this bit is set to 1, only +18V or -18V is available from SUMER 4. In this case, all MCs are moved sequentially and the ADCs are switched off during motion. This bit has to be set in addition to the SUMER 4 configuration bits!
Bit 67: Enable HK Monitor Setting this bit to 1 enables the HK monitor. If a HK value is out of range, an emergency switch off will be executed. Setting this bit to 0 disables the HK monitor.
Bit 68: Enable Watchdog Setting this bit to 1 enables the watchdog monitor process. The watchdog process observes several processes to verify that the program is still running. The watchdog is triggered only if every process observed sends a tag within an individual time period. Setting this bit to 0 disables the watchdog monitor process. The watchdog is now triggered every 300 ms.
Bit 69: Enable closing door on ESR warning
Setting this bit to 1 enables the closing of MC1Door in case of ESRwarning. Setting this bit to 0 disables the closing of MC1Door in case of ESRwarning.

The L4 commands are arranged in 8 groups:
After each L4 command, the HK record #249 containing the command parameters and the command results is transmitted to the EGSE. Every routine in each group has an individual set of return parameters. All return parameters are of type INT32. The positions of the return parameter within the HK record #249 are shown in the tables with R#.
The result of the level 4 function executed is returned in HK record #249 in position 17 (bytes 68 - 71). Additional data resulting from execution of the L4 command are shown in the tables.
