Incorrect data format for CIP Identity Object Instance Attribute 19 (Protection Mode) in GetAttributeAll Response

Test Description:

1. Access Identity Object mandatory Class and Instance Attributes via network and host interface.
2. Validate Identity Object mandatory Class and Instance Attributes values.
3. Check Identity Object mandatory Class and Instance Attributes supported services.

Bug description from tester:

Information for Instance attribute 19- Protection mode retrieved via Get Attribute Single and Get Attribute All differs. Protection mode is enabled and in one case retrieved data is 0x0001 and in the other case it is 0x0100, which is confusing and may lead to incorrect interpretation of the retrieved data.

Steps to reproduce:

1. Execute Get_Attribute_All (0x01) service to Identity Object Instance attributes via Host Application or Network

2. Check retrieved data

3. Execute Get_Attribute_Single (0x01) service to Identity Object  Instance attributes via Host Application or Network

4. Check retrieved data

Expected results:

1. Data retrieved via Get Attribute All - 0x0100 , Data retrieved via Get Attribute Single - 0x0100

Actual results:

1. Data retrieved via Get Attribute All - 0x0001 , Data retrieved via Get Attribute Single - 0x0100
