User bit 2
The bits are reset in the magazine table if ASCII code 0 = 30H and are set if ASCII code
1 = 31H. The standard bits in word 1 are defined in DB 152 (identification bits of the
magazine table).
Valid for "Write data" only.
If the ASCII code of one or more of the four signals is not equal to 30H or 31H, the
respective signals maintain their status.
The user bits are assigned by means of the following machine data specifications:
User bit 1: defined via MD 2078 = DB 61, DW 78
Bit number
User bit 2: defined via MD 2079 = DB 61, DW 79
Bit number
Bit numbering starts at 0 to 15.
When defining the machine data, it should be ensured that the data are entered in KF
format. The value to be entered is derived from the following equation:
MD 2078/MD 2079 = bit No.
The data word address of the target locator No. is determined and specified by the data
distributor via the current magazine and locator No.
The target specifications must be entered by the user.
b) The identifications are coded bitwise
– For source = computer :
– For source = tape
