Rockwell Automation 1747-ASB Remote I/O Adapter - Manual (Page 71)

Publication 1747-UM006B-EN-P - June 2003
Configuration 4-17
Processor Restart Lockout (SW3-2)
SW3 switch 2 determines whether your system automatically resumes
RIO link communications with the scanner when:
•
Link communications are temporarily interrupted. For example,
by removing and replacing the RIO connector.
•
The 1747-ASB module is inhibited and re-enabled.
Processor Restart Lockout DIP Switch Settings
While in the OFF position (lock processor out) and communications
are restored, the 1747-ASB module does not respond to any
communication commands until 1747-ASB module terminals IN and
RET are momentarily shorted together. Processor restart lockout
prevents RIO link communications (by locking out the scanner and
processor) and does not allow the 1747-ASB module to exchange any
I/O data or respond to any RIO commands, such as reset adapter reset
commands.
RIO link communications can be restarted by:
•
momentarily shorting pins 5 and 6 together (See chapter 5 for
wiring information.)
•
cycling power on any chassis controlled by the 1747-ASB
module
While in the ON position, the 1747-ASB module always attempts to
restart communications with the scanner if RIO link communications
are interrupted or if the 1747-ASB module is inhibited and re-enabled.
While in the ON position, the 1747-ASB module does not respond if
terminals 5 and 6 are shorted together.
The 1747-ASB module is shipped from the factory with the default
position ON (automatic restart).
