Honeywell R0512 manual Write Protection

EXCEL 50/100/500/600/800 ATTRIBUTES

Write Protection

The attribute "Write Protection" (XBS, only) prevents data from being overwritten. The default setting of the attribute is 0 (="No"). If the datapoint should be protected, then "No" must be overwritten with a value between 0 and 100.

0 = No write protection

100 = Highest priority required

To change this attribute, the operator must log in at an operator level that corresponds to the current write protection attribute (see Table 16).

Table 16. Access values for operator levels

	operator level XBS		access for write protection values
	1		no access
	2		no access
	3		0 to 60
	4		0 to 80
	5		0 to 100
	The operator's authority level is compared to the write protection status of the
	datapoint to establish whether or not any modification can be made.
	As soon as the operator receives permission, he can alter the attribute of secured
	datapoints. The operator can also set the write protection to a higher value or
	cancel write protection completely.
Example:	A datapoint with a write protection value of 61 can be altered only at operator level
	4 or 5.
	The write protection can be reduced to 0 from level 4 as well as level 5. The
	datapoints can be altered through level 3. A detailed high priority can then be given
	through the write protection.
	NOTE:	When online, the XI581 (not with XCL5010, Excel 100C), XI582, and XL-
		Online operator interfaces and the XL50-MMI do not recognize the
		attribute "Write Protection". You can still change any datapoint via the
		user interface, even if the datapoint is write-protected.
