A value defining how and when the command takes effect. The value is a sum. This value initially takes the value zero, then for each place the parameter can be set from, 2 raised to a power is added to the sum. The powers are according to the following table: Set From Power Console 0 AUTOEXEC.NCF 1 STARTUP.NCF 2 For example, a parameter that can be set from either the console or AUTOEXEC would have a value of 3 (2**0 + 2**1). On a read, a bit will be set for each place the parameter can be set from. On a write, bits should be set to specify where the set command should be placed. If nwSetParamValue is written without nwSetParam also being set in the same PDU, the parameter will be set as if at the console; unless it is a parameter which can only be set in STARTUP.NCF in which case an error will be returned
