MEMO:  Relay group comments with up to 512 characters enclosed in quotation marks.

TAG: Tag string with a maximum of 512 characters.  Tags in string are separated by semicolon. Any alpha-numeric characters can be used, except for the string delimiter (single or double quotation mark).  The tag string is enclosed in quotation marks.

ASSETID: Asset ID string with a maximum of 128 characters enclosed in quotation marks.

FLAG: Device on/off- line flag. Set flag to 1 for on-line device; 2 for off-line device.

ELETYPE: Protective device type. Enter 101 for voltage relay; 102 for line differential relay

For voltage relay include the following fields

VOPERATE: Operating quantity code: 1 for L-N voltage; 2 for L-L voltage; 3 for 3V0; 4 for V1; 5 for V2; 6 for Va; 7 for Vb; 8 for Vc; 9 for Vbc; 10 for Vab; 11 for Vca

SGNLONLY: Signal only flag. Enter an integer number all the bits at positions that correspond to signal only element set: 1 for over-voltage instantaneous; 2 for over-voltage with time delay; 3 for under-voltage instantaneous; 4 for under- voltage with time delay. The rest of the bits are reset; For example to indicate over-voltage instantaneous and under-voltage instantaneous as signal only, enter 5 (1st and 3th bits are set).

PTRATIO:  PT ratio as string in one of the following format X, X:Y or X/Y. Can have up to 12 characters enclosed in quotation marks.

OVINST: Over-voltage instantaneous setting in secondary amperes.

OVPICKUP: Over-voltage time element pickup setting in secondary amperes.

OVTDDELAY: Over-voltage definite time element delay in seconds or the inverse time curve time dial.

OVCURVE: Over-voltage inverse time curve enclosed in quotation mark. The curve must be empty if the element has definite time delay.

UVINST: Under-voltage instantaneous setting in secondary amperes.

UVPICKUP: Under -voltage time element pickup setting in secondary amperes.

UVTDDELAY: Under -voltage definite time element delay in seconds or the inverse time curve time dial.

UVCURVE: Under -voltage inverse time curve enclosed in quotation mark. The curve must be empty if the element has definite time delay.

LIBNAME: Name of relay library file containing the curves used in relay inverse time elements.

For line differential relay include the following fields

PICKUPPH: Minimum enable phase differential current.
