3.1 Equipment and Tools
Have the following tools and equipment ready:
• SLC programming equipment
• terminal emulation software
• null modem cable, 9-pin female to female (provided by SST)
• AS-i cable to connect the scanner to the AS-i network
• AS-i power supply
3.2 Procedures
1. Unpack the module. Make sure you received the AS-i scanner and a
serial null modem cable for configuring I/O.
2. Review the power requirements of your system to verify that your
chassis supports placement of the scanner module. The scanner
consumes 500 mA at 5 VDC.
Calculate the total load on the system power supply using the
procedure described in the
SLC 500 Modular Style Installation &
Operation Manual , Allen-Bradley Publication 1747-6.2 or the SLC
500 Family System Overview , Publication 1747-2.30.
3. Make sure system power is off. Insert the scanner module into your
1746 chassis. Connect AS-i power to the scanner. The slaves require
AS-i power to be able to communicate with the scanner.
Refer to chapter 5 in this guide if you need help installing or wiring
the module.
4. Set up your system I/O configuration for the particular slot where
you installed the scanner. Using APS or RSLogix 500 software,
configure the scanner as
Other and enter the scanner module ID
(
13635
).
Refer to chapter 6 for details on configuring the scanner with several
popular programming packages. RSLogix 500 users should refer to
section 6.3 for important information on dealing with a G file
problem in RSLogix.
5. Set the M1 and M0 file sizes to 40 words.
6. Set scanned inputs and outputs to 32 words.
7. Set the G file size to 64 words.
