10. Diagnostics messages of the operating system10. Diagnostics messages of the operating systemDiagnostic operands are used in order to obtain information regarding operating statesin the program (this functionality can only be used when the base device is in RUNmode). If the described event has occurred, the operands will have a state of 1.Operand EventID01 There are more than two devices in this NET group and the NET is active. The following NET sta-tion is not present:1ID02 There are more than two devices in this NET group and the NET is active. The following NET sta-tion is not present:2ID03 There are more than two devices in this NET group and the NET is active. The following NET sta-tion is not present:3ID04 There are more than two devices in this NET group and the NET is active. The following NET sta-tion is not present:4ID05 There are more than two devices in this NET group and the NET is active. The following NET sta-tion is not present:5ID06 There are more than two devices in this NET group and the NET is active. The following NET sta-tion is not present:6ID07 There are more than two devices in this NET group and the NET is active. The following NET sta-tion is not present:7ID08 There are more than two devices in this NET group and the NET is active. The following NET sta-tion is not present:8ID09 The DCF77 radio time signal has been enabled in the program. A radio signal is not being detectedat the selected input.ID10 This diagnostic bit is set if one of the following time synchronization operations could not be com-pleted successfully:l "Synchronize clock via NET"l "SNTP synchronisation"l Date and timel DCF77 radio clockUsing the SC function block will not result in this error message or in it being cleared.ID11 If the device cannot communicate via Ethernet.ID12 Arithmetic blocks have their own error output that is used to signal whether there is a numeric under-flow/overflow, e.g., as a result of attempting to divide by zero. When using the ST programminglanguage, this diagnostic operand will additionally be set if such an error occurs.ID13 If the base device is being operated with one or more expansion devices, this diagnostic operandwill indicate whether required devices are disconnected from the easyConnect bus or are not beingdetected, e.g., in the event of a power failure on an expansion device.ID14 Transistor outputs in the base device are experiencing an overload or a short circuit; the outputs willbe switched off and then checked again after 30 seconds.ID15 –ID16 –ID17 –ID18 –ID19 There is an interrupt overload. One or more interrupt function blocks are being used, and the interrupteasyE4 11/18 MN050009 EN www.eaton.com 517
