6-10 C30 Controller System GE Multilin6.2 STATUS 6 ACTUAL VALUES66.2.18 TELEPROTECTION CHANNEL TESTSPATH: ACTUAL VALUES STATUS TELEPROT CH TESTSThe status information for two channels is shown here.• CHANNEL 1 STATUS: This represents the receiver status of each channel. If the value is “OK”, teleprotection isenabled and data is being received from the remote terminal; If the value is “FAIL”, teleprotection enabled and data isnot being received from the remote terminal. If “n/a”, teleprotection is disabled.• CHANNEL 1 LOST PACKETS: Data is transmitted to the remote terminals in data packets at a rate of two packets percycle. The number of lost packets represents data packets lost in transmission; this count can be reset to 0 through theCOMMANDS CLEAR RECORDS menu.• VALIDITY OF CHANNEL CONFIGURATION: This value displays the current state of the communications channelidentification check, and hence validity. If a remote relay ID does not match the programmed ID at the local relay, the“FAIL” message will be displayed. The “N/A” value appears if the local relay ID is set to a default value of “0”, the chan-nel is failed, or if the teleprotection inputs/outputs are not enabled.6.2.19 REMAINING CONNECTION STATUSPATH: ACTUAL VALUES STATUS COMM STATUS REMAINING CONNECTThese values specify the remaining number of TCP connections still available for each protocol. Every time a connection isused, the remaining number of connections decrements. When released, the remaining number of connections increments.If no connection is made over the specific protocol, the number equals the maximum number available for the specific pro-tocol.For example, the maximum number of Modbus TCP connections is 4. Once an EnerVista session is opened on a computerconnected to the UR over Ethernet, the Modbus TCP status shows 3. If the EnerVista application is closed, the ModbusTCP status shows 4.Note that the maximum number of PMU TCP connections matches the number of aggregators.
