 *   This plugin for program plc requests device attributes using
 *   a VS_OP_ATTRIBUTES message; attributes are pre-parsed versions
 *   of information returned by VS_SW_VER and other messages;
 *
 *   The VS_OP_ATTRIBUTES message structure changed between FW 3.3.4
 *   and 3.3.5 and fields are ocassionally appended to the end; you
 *   should not use this message for operational systems because the
 *   format may change again; it was originally intended for PTS use
 *   only;
