DM255 / 254 / 120 Data Modules 6-5
6.3.1 Automatic Diagnostic Range
In the event of a fault occurrence, the DIAG500E diagnostics module will
automatically enter diagnostic data into the data words identified below.
The respective data words are then read by BTSMADAP and, subsequent
to processing for display in the BT5 / BT20 operator terminals, will be
written to the BTS_Diag data module (DM254).
Date Format
The system time and date of an occurring first-value error are written to
the data words D2 through D8 in hex notation. The weekday is coded as
follows:
• 0 = Sunday
• 1 = Monday
• 2 = Tuesday
• 3 = Wednesday
• 4 = Thursday
• 5 = Friday
• 6 = Saturday
Step Number
Data byte D10 indicates the step number of the faulty cascade.
Cascade Number
Data byte D11 indicates the cascade number of the faulty cascade.
Module Number
Each cascade is programmed by the user in an associated function mod-
ule. The number of that function module is stored in data byte D12, and
corresponds to both the cascade number and the cascade data module
number.
Module Type
Data byte D13 indicates the module type of the faulty cascade. In the
case of the CL200, CL400, and CL500, the value of = 1
bin
, indicating the
function module, is entered here.
Number of Messages
Data byte D14 contains the number of conditions belonging to the first-
value error. The representation occurs in hex notation. As only the first 64
conditions are stored, the number of messages is set to 65 in the event
that the BEFA command output or WSB step-on condition branch should
consist of more than 64 conditions.
Cascade Status
Data byte D15 indicates the OpMode of the faulty cascade at the time the
first-value error occurred.
• Bit 0 (value 1) = Cascade in Manual mode
• Bit 1 (value 2) = Cascade in Inching mode
• Bit 2 (value 4) = Cascade in Automatic mode
