This object is a table control variable for adding or deleting RTU entries in multilink mode: setting it to add(2) creates a new row with a default placeholder address of 65534 that must then be reconfigured, setting it to delete(3) removes all fields for that RTU, and setting it to valid(1) does nothing while a read of 1 confirms the row exists. Admins use this to provision or remove RTUs from a multilink IEC-101 line, following the rule that a new row must be added immediately after the last index and that address 65534 must not already be in use. For example, an admin sets telProdNpIec101GWIfcRtuStatus to add(2) to create a new RTU entry, then immediately configures its real link address via telProdNpIec101GWIfcRtuAddress.
