4.3 Configuring the AS-i Scanner
When you first configure your AS-i system, you must initially set some basic
options in the G file. Then you may enter and manipulate the rest of your
network configuration using either the G file or the serial port. This section
discusses both methods of configuration.
4.3.1 G File vs. Serial Port Configuration
The serial port method of configuration is much quicker when you are
hooking up the scanner to an existing (and present) network. However, the
network configuration will not be part of the SLC program.
The G file method not only saves the configuration, it also allows you to
archive the configuration and load it on to another system. If the SLC or
scanner fails, you can easily replace the failed device and reconfigure the
system with the archived G file.
4.3.2 G File Configuration
Option bits in the G file affect the way the scanner operates with respect to
parameters and to I and O file usage.
You must do at least some configuration via the G file. At bare minimum, you
must set the scanner ID (word 63) and indicate the AS-i channel(s) you are
using (C bits - words 1 and 32, bit 15). If you try to run without setting these
bits in the G file, the scanner will fault with a G file error (70H).
You may go on to use the serial port for the rest of the configuration or you
can continue network setup in the G file.
There are 4 other bits in the G file that affect the scanner behaviour: W, A, F
and G bits.
If you set the W bit(s), the parameters from the output file are used and slave
parameter echoes are put into the input file. If you do not set the W bit(s), the
output file parameters are ignored.
Setting the A bit(s), enables Auto Address Programming.
If you set the G bit(s), the network configuration from the G file is used.
If you set the F bit(s), the SLC will continue to operate when any AS-i fault
occurs.
