CHAPTER 5: SETTINGS PRODUCT SETUPB90 LOW IMPEDANCE BUS DIFFERENTIAL SYSTEM – INSTRUCTION MANUAL 5-395The DNP TCP CONNECTION TIMEOUT setting specifies a time delay for the detection of dead network TCP connections. Ifthere is no data traffic on a DNP TCP connection for greater than the time specified by this setting, the connection isaborted by the B90. This frees up the connection to be re-used by a client. Any change takes effect after cycling power tothe relay.5.3.5.11 DNP / IEC 60870-5-104 point listsSETTINGS PRODUCT SETUP COMMUNICATIONS DNP / IEC104 POINT LISTSUp to 256 binary and up to 256 analog input points for the DNP protocol, or the MSP and MME points for IEC 60870-5-104protocol, can be configured. The value for each point is user-programmable and can be configured by assigning FlexLogicoperands for binary inputs / MSP points or FlexAnalog parameters for analog inputs / MME points.The menu for the binary input points (DNP) or MSP points (IEC 60870-5-104) follows.SETTINGS PRODUCT SETUP COMMUNICATIONS DNP / IEC104 POINT LISTS BINARY INPUT / MSP POINTSUp to 256 binary input points can be configured for the DNP or IEC 60870-5-104 protocols. The points are configured byassigning an appropriate FlexLogic operand. See the Introduction to FlexLogic section in this chapter for the range ofassignable operands.Changes to the DNP / IEC 60870-5-104 point lists take effect when the B90 is restarted.The menu for the analog input points (DNP) or MME points (IEC 60870-5-104) follows.SETTINGS PRODUCT SETUP COMMUNICATIONS DNP / IEC104 POINT LISTS ANALOG INPUT / MMEPOINTSUp to 256 analog input points can be configured for the DNP or IEC 60870-5-104 protocols. The analog point list isconfigured by assigning an appropriate FlexAnalog parameter to each point. See the FlexAnalog Parameters section inAppendix A for the range of assignable parameters.Changes to the DNP / IEC 60870-5-104 point lists take effect when the B90 is restarted.

Since DNP / IEC60870-5-104 point lists must be in one continuous block, any points assigned after the first “Off” point are ignored.
