4-18 Configuration

If the 1747-ASB module has not received communications for all of its
logical devices, you are able to perform PLC auto configurations once
the 1747-ASB module is powered up. If processor restart lockout is
not
selected, you are able to perform PLC auto configurations on the
1747-ASB module.

Link Response Time (SW3-3)

SW3 switch 3 allows you to select a longer (restricted) response time
when communicating at 57.6K and 115.2K baud. 230.4K baud
operates with a short (unrestricted) response time, regardless of the
switch setting.

The link response time is the time it takes an adapter to respond to
data received from the scanner. Some scanners require a longer
response time than other scanners. Operating unrestricted reduces
overall RIO scan time, but requires a faster scanner.

ATTENTION

!

Cycling power on any chassis removes the processor
restart lockout condition.

IMPORTANT

After communications to all of the 1747-ASB
module's logical devices are established, selecting
processor restart lockout disables PLC auto
configurations on the 1747-ASB module.

IMPORTANT

Selecting processor restart lockout affects the
1747-ASB module inhibit functionality.
