76 SI-INTERBUS User GuideIssue Number: 114.4 Interbus operating statusIf the operating status shows a negative number, this indicates that the SI-Interbus is notcurrently communicating with the Interbus master controller. Values above 0 indicate thenumber of messages per second being processed.If Pr MM.006 shows a positive value, this value is dependent upon the Interbus networkcommunication speed, number of mappings and whether non-cyclic communicationsare active or not.14.5 Network loss timeoutThe SI-Interbus resets an internal timer when a valid message is received from theInterbus network. The network loss trip is triggered when no new messages arereceived before the timer times out. The value is in units of milliseconds.The size of the data mapping will depend on the total size of the target / sourceparameters. Parameters of 16-bits or less will be cast as 16-bits if MM.34 DataCompression Enable = On, but will be cast as 32-bits if MM.34 Data CompressionEnable = Off. Parameters larger than 16-bits will always be cast as 32-bits on thenetwork.NOTENOTEMM.006 SI-Interbus Operating StatusMinimum -3 Maximum 9999Default None Units NoneType 16 Bit Volatile Update Rate Background updateDisplay format None Decimal Places 0Coding RO, ND, NC, PTPr MM.006 Description> 0 Network healthy, displays the number of messages processed per second0 Network health, no cyclic data transfer-1 SI-Interbus has initialised correctly and waiting for the Interbus master toinitialise communication-2 The SI-Interbus module reports an internal hardware fault-3 Configuration error, invalid setting in the SI-Interbus configurationparametersMM.007 Network Loss TimeoutMinimum 0 Maximum 3000Default 200 Units msType 16 Bit User Save Update Rate Background readDisplay format None Decimal Places 0Coding RW, BU |
