STB NIP 2212
Status Register Register 45391 contains a word of diagnostic data that is allocated to the status of
the STB NIP 2212. The bits in the high byte have predefined meanings that are
common to all of the NIMs used with the Advantys STB island. The low byte is
reserved for the particular use of each specific NIM:
1 Module failure—bit 8 is set to 1 if any module on the island bus fails.
2 A value of 1 in bit 9 indicates an internal failure—at least one global bit was set.
3 A bit value of 1 in bit 10 indicates an external failure—the problem is on the fieldbus.
4 A value of 1 in bit 11 indicates that the configuration is protected—the RST button is
disabled, and the island configuration requires a password to write to it; a bit value of 0
indicates that the island configuration is unprotected—the RST button is enabled, and the
configuration is not password-protected.
5 A value of 1 in bit 12 indicates that the configuration on the removable memory card is
invalid.
6 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.
