CHAPTER 5: SETTINGS PRODUCT SETUPC70 CAPACITOR BANK PROTECTION AND CONTROL SYSTEM – INSTRUCTION MANUAL 5-875IEC 60870-5-104 is a transmission protocol for network access, specifically for communication between a control stationand substation over a TCP/IP network.The C70 supports the IEC 60870-5-104 protocol. This protocol is enabled when the SETTINGS PRODUCT SETUP COMMUNICATIONS PROTOCOL setting is set to IEC 60870-5-104. The C70 can be used as an IEC 60870-5-104 slave deviceconnected to a maximum of two masters (usually either an RTU or a SCADA master station). Since the C70 maintains twosets of IEC 60870-5-104 data change buffers, ideally no more than two masters actively communicate with the C70 at onetime.The IEC ------- DEFAULT THRESHOLD settings are used to determine when to trigger spontaneous responses containingM_ME_NC_1 analog data. These settings group the C70 analog data into types: current, voltage, power, energy, and other.Each setting represents the default threshold value for all M_ME_NC_1 analog points of that type. For example, to triggerspontaneous responses from the C70 when any current values change by 15 A, the IEC CURRENT DEFAULT THRESHOLDsetting is set to 15. Note that these settings are the default values of the deadbands. P_ME_NC_1 (parameter of measuredvalue, short floating point value) points can be used to change threshold values, from the default, for each individualM_ME_NC_1 analog point. Whenever power is removed and re-applied to the C70, the default thresholds are in effect.The IEC REDUNDANCY setting decides whether multiple client connections are accepted or not. If redundancy is set to Yes,two simultaneous connections can be active at any given time.IEC TCP PORT NUMBER — To close the port, set the port number to 0. The change takes effect when the C70 is restarted.SETTINGS PRODUCT SETUP COMMUNICATIONS IEC 60870-5-104 PROTOCOL IEC NETWORK CLIENTADDRESSES IEC COMMON ADDRESSOF ASDU: 0Range: 0 to 65535 in steps of 1 IEC CYCLIC DATAPERIOD: 60 sRange: 1 to 65535 s in steps of 1 IEC CURRENT DEFAULTTHRESHOLD: 30000Range: 0 to 65535 in steps of 1 IEC VOLTAGE DEFAULTTHRESHOLD: 30000Range: 0 to 65535 in steps of 1 IEC POWER DEFAULTTHRESHOLD: 30000Range: 0 to 65535 in steps of 1 IEC ENERGY DEFAULTTHRESHOLD: 30000Range: 0 to 65535 in steps of 1 IEC PF DEFAULTTHRESHOLD: 1.00Range: 0.00 to 1.00 IEC OTHER DEFAULTTHRESHOLD: 30000Range: 0 to 65535 in steps of 1 IEC REDUNDANCYENABLED: NoRange: No, YesThe C70 relay does not support energy metering.
