During module configuration, the OK will be red and the APP and BP ACT LEDs
will be on. If the LEDs are latched in this mode for a long period of time, look at
the configuration error words in the configuration request block. The structure of
the block is shown in the following table:
Offset Description Length
0 Reserved 1
1 9000 1
2 Module Configuration Errors 1
3 Port 1 Configuration Errors 1
4 Port 2 Configuration Errors 1
5 to 248 Spare 244
249 -2 or -3 1
The bits in each configuration word are shown in the following table. The module
configuration error word has the following definition:
Bit Description Value
0 Read block start value is greater than the database size. 0x0001
1 Read block start value is less than zero. 0x0002
2 Read block count value is less than zero. 0x0004
3 Read block count + start is greater than the database size. 0x0008
4 Write block start value is greater than the database size. 0x0010
5 Write block start value is less than zero. 0x0020
6 Write block count value is less than zero. 0x0040
7 Write block count + start is greater than the database size. 0x0080
8 0x0100
9 0x0200
10 0x0400
11 0x0800
12 0x1000
13 0x2000
14 0x4000
15 0x8000
The port configuration error words have the following definitions:
Bit Description Value
0
