22.46 22.46 If programmable protective electronic circuits are used to ensure compliance with this standard, the software shall contain measures to control the fault/error conditions specified in Table R.1.
Software that contains measures to control the fault/error conditions specified in Table R.2 is to be specified in parts 2 for particular constructions or to address specific hazards, if necessary.
These requirements are not applicable to software used for functional purpose or for compliance with Clause 11.
Compliance is checked by evaluating the software in accordance with the relevant requirements of Annex R.
If the software is modified, the evaluation and relevant tests are repeated if the modification influences the results of the test involving protective electronic circuits.
NOTE Measures used for software to control the fault/error conditions specified in Table R.2 are inherently acceptable for measures used for software to control the fault/error conditions specified in Table R.1.
为符合本标准而设置的可编程保护电子电路，软件需要包含措施以控制表R.1中所述的故障/错误情况。
如有必要，包含对表R.2中所述的故障/错误情况处理措施的软件的特殊结构，或具体的危险，在特殊标准里规定措施的软件。
这些要求不适用于实现功能目或为符合11章而设的软件。
依据附录R通过软件评估确定其是否合格。
如果软件被修改，且修改影响到保护电子电路的试验结果，则评估与相关试验应重新进行。
注 控制表R.2中所述的故障/错误的软件措施适用于控制表R.1中所述的故障/错误的软件措施。 22.46 Software used in protective electronic circuits shall be software class B or software class C.
NOTE 1 Failure of software class B in the presence of another fault in the appliance, or failure of software
class C alone, could result in dangerous malfunction, electric shock, fire, mechanical or other hazards. Software class A denotes software used for functional purposes.
Compliance is checked by evaluating the software in accordance with Annex R.
NOTE 2 If the software program is modified, the evaluation and relevant tests are repeated if the modification can influence the results of the test involving protective electronic circuits.
