Fixed Allocations Section 4-3

4-3-3 Changing System Components

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.

4-3-4 Fixed Allocations Example

This example shows the allocations that are used when Fixed Allocations 1 are used for the following slaves.

2	0 pts	16 pts	16-pt Transistor Input Terminal
			(DRT1-ID16)
3	16 pts	0 pts	16-pt Transistor Output Termi-
			nal (DRT1-OD16)
4	8 pts	8 pts	8-pt Input and 8-pt Output Envi-
