The scan list must be cleared in the following situations:
• Adding a slave
• Removing a slave
• Changing a node address
Turn OFF the Scan List Clear Switch (word n, bit 01) to clear the scan list.
Remote I/O communications will be performed with the scan list disabled
using fixed allocations in the fixed allocations area that was used the last time
the list was disabled. Make sure that communications with all slaves are oper-
ating properly after the scan list is cleared and the system component is
changed, and then turn ON the Scan List Enable Switch (word n, bit 00) again
to register all slaves currently online in the scan list. Remote I/O communica-
tions will continue during this time with the scan list enabled.
This example shows the allocations that are used when Fixed Allocations 1
are used for the following slaves.
