CLS. 3.4.1 CLS is the designated agent of CNES to operate the Argos system ground segment and to promote the use of it. Those Argos basic services are provided at cost to the users under the oversight of the Argos Operation Committee (CNES, NOAA, EUMETSAT).
CLS. The calculation of the CLs for each of the three control charts is similar to the calculation of the annual Availability performance indices described in Section 4.3.1 except that the period for which data are to be included in the calculations is expanded from a single calendar year to the ten years, unless a shorter period is justified by the PTO, for the period immediately preceding the ISO Operations Date, or immediately preceding the date a TO becomes a PTO. To account for this change a count of Transmission Line Circuit years is included in the equations as shown below to enable derivation of CLs which represent average performance during a multi-year period.

To account for this change a count of Transmission Line Circuit years is included in the equations as shown below to enable derivation of CLs which represent average performance during a multi-year period. CL for Annual Transmission Line Circuit Forced Outage(IMS) Frequency Y Nk Y CLfvc = S S fik / ( S Nk) k-1 i-1 k=1 where CLfvc = center control line value for the Forced Outage(IMS) frequencies for each of the Transmission Line Circuits in the Voltage Class for Y years prior to the ISO Operations Date, or the date a TO becomes a PTO. Y = number of years prior to the ISO Operations Date (or the date a TO becomes a PTO) for which the PTO has reliable, continuously recorded Outage(IMS) data. Y=10 is preferred. CL for Annual Accumulated Forced Outage(IMS) Duration for those Transmission Line Circuits with Forced Outages(IMS) Y No,k Y CLdvc = S S dik / ( S No,k) k-1 i-1 k=1 where CLdvc = center control line value for accumulated Forced Outage(IMS) duration for each of the Transmission Line Circuits in the Voltage Class for Y years prior to the ISO Operations Date (or the date a TO becomes a PTO) in which the Forced Outage(IMS) frequency (fik) was greater than zero. CL for Annual Proportion of Transmission Line Circuits with No Forced Outages(IMS) Y CLPvc = S (Nk - No,k) k=1 Y S Nk k=1 where CLPvc = center control line value for the proportion of Transmission Line Circuits in the Voltage Class with no Forced Outages(IMS) for Y years prior to the ISO Operations Date, or the date a TO becomes a PTO.
CLS. Use The CLear Status command clears status data structures, i.e. standard event status registers, so that the corresponding summary ESB bit is clear. See also chapter IEEE Standard Status Data Structure. Example : → *CLS Explanation *CLS has same effect as *ESR? query, except it is a command. *ESE Use The standard Event Status Enable command sets the standard event status enable register bits. The standard event status enable register allows one or more events in the standard event status register to be reflected in the ESB summary-message bit. See also chapter IEEE Standard Status Data Structure. Parameter <Enable_value> Byte Range 0 to 255 Example : → *ESE 32 (enables command error event) *ESE? Use The standard Event Status Enable query allows the programmer to determine the current contents of the standard event status enable register. See also chapter IEEE Standard Status Data Structure. Parameter <Enable_value> Byte Range 0 to 255 Example : → → : *ESE? *SRE Use The Service Request Enable command sets the service request enable register bits. The service request enabling allows a programmer to select which summary messages in the status Byte register may cause service request (SRQ). The programmer can select reasons to issue a service request by altering the contents of the service request enable register. See also chapter IEEE Standard Status Data Structure. Parameter <Enable_value> Byte Range 0 to 255 Example : → *SRE 32 (enables standard event status bit [ESB]) *SRE?
