NIM Status
The high and low bytes in register 45391 report the status of the INTERBUS NIM:
1 The combined value of bits 0 and 1 indicates the NIM version. A value of 1 indicates the
economy version. A value of 2 indicates the standard version. A value of 3 indicates the
premium version.
2 A value of 1 in bit 2 indicates that either the input or output data exceeds its word limit. A
value of 0 indicates that both the input and output data are within their respective word
limits.
3 The combined value of bits 4 through 7 indicate errors that occur during island bus
scanning. A value of 0x00 indicates no error. A value of 0x01 indicates a self-test failure.
A value of 0x02 indicates at least one global bit has been set. A value of 0x03 indicates an
expired request timer. A value of 0x04 indicates an empty assembly list. A value of 0x05
indicates an expired confirm timer. A value of 0x06 indicates a wrong island bus state at
initialization. Values from 0x07 to 0x0F are reserved.
4 Module failure—A value of 1 in bit 8 indicates the failure of an island bus module.
5 A value of 1 in bit 9 indicates an internal failure—at least one global bit is set.
6 A bit value of 1 in bit 10 indicates an external failure—the problem is on the fieldbus.
7 A value of 1 in bit 11 indicates that the configuration is protected—the RST button is
disabled and the configuration software requires a password before you can write. A bit
value of 0 indicates that the configuration is standard—the RST button is enabled and the
configuration software is not password-protected.
8 A value of 1 in bit 12 indicates that the configuration on the removable memory card is
invalid.
9 A value of 1 in bit 13 indicates that reflex action functionality has been configured. (For
NIMs with firmware version 2.0 or greater.)
10 A value of 1 in bit 14 indicates that one or more island modules have been hot-swapped.
(For NIMs with firmware version 2.0 or greater.)
11 Island bus output data master—A value of 0 in bit 15 indicates that the fieldbus master
device is controlling the output data of the island’s process image. A bit value of 1 indicates
that the Advantys configuration software is controlling the output data of the island’s
process image.
