7.1 G File
For these steps, refer to the G File Layout Table on page 41.
1. Set word 63 of the G file to 13635 decimal. This is the scanner ID.
2. Set the C bits. These are the Channel enable bits.
The C bits are bit 15 of words 1 (Channel 1) and 32 (Channel 2). If
the C bit is 1, the Channel is active. If the C bit is 0, the Channel is
inactive. If the C bit is not set for either channel, the SLC faults with
error code 70h (G file error) and the FAULT LED flashes red when
you go to run mode.
3. Set the A bits. These are the Auto Address Programming bits.
The A bits are bit 13 of words 1 (Channel 1) and 32 (Channel 2). If
the A bit is 1, Auto Address Programming is enabled. If the A bit is
0, Auto Address Programming is disabled.
Auto Address Programming allows you to replace one failed slave
with a matching slave at address 0. The new slave will be
reprogrammed automatically by the scanner to the missing address.
If more than one slave is at fault, Auto Address Programming is
unavailable.
4. Set W bits if required. The W bits are the write parameter enable
bits.
The W bits are bit 14 of words 1 (Channel 1) and 32 (Channel 2). If
the W bit is 1, you can change the parameters while running, via the
output file. If the bit is 0, you cannot change parameters while
running.
5. Set the G bits. These are the G file enable bits.
The G bits are bit 15 of words 2 (Channel 1) and 33 (Channel 2). If
you want to use the network configuration from the G file, set the G
bit to 1. Otherwise, you must configure your network using the
Config port on the AS-i scanner module.
NOTE: When the G bit is 0, the C, A and W bits of the G file are still
used.
6. Set the F bits if required. These are the “don’t fault” bits.
The F bits are bit 14 of words 2 (Channel 1) and 33 (Channel 2). Set
these bits if you want the SLC to continue operation when any AS-i
fault occurs.
