Device-defined data types (Modbus Slave)

Device-defined data type names vary for each serial protocol depending on the Channel
selection in Device definition
. These tables describe the device-defined data types created for the Master Slave protocol. The tables include information for input (as indicated by an "I") and information for output (as indicated by an "O").

Device-defined data type: AB:5000_ModbusSlave:I:0
Name	Type	Definition	Valid Values
RunMode	BOOL	Channel operating state.	0 = Idle 1 = Run Mode
ConnectionFaulted	BOOL	Indicates if the connection is running. The device sets value to 0 when connected and then changes value to 1 when not connected.	0 = Connection running 1 = Connection is not running
DiagnosticActive	BOOL	Indicates if any diagnostics are active or if the prognostics threshold is reached.	0 = No diagnostics active 1 = One or more diagnostics are active or the prognostics threshold is reached
DiagnosticSequenceCount	SINT	Diagnostic counter. The value increments each time a distinct diagnostic condition is detected, and again when the condition transitions from detected to not detected. Set to zero by product reset or power cycle. Wraps from 255 (-1) to 1 skipping 0.	-128 to +127 The value of 0 is skipped except during device power-up.
Slave	AB:5000_ModbusSlave_Channel:I:0	Channel array configurations

Device-defined data type: AB:5000_ModbusSlave:I:1
Name	Type	Definition	Valid Values
RunMode	BOOL	Channel operating state.	0 = Idle 1 = Run Mode
ConnectionFaulted	BOOL	Indicates if the connection is running. The module sets this value to 0 when connected and then changes the value to 1 when not connected.	0 = Connection running 1 = Connection is not running
DiagnosticActive	BOOL	Indicates if any diagnostics are active or if the prognostics threshold is reached.	0 = No diagnostics active 1 = One or more diagnostics are active or the prognostics threshold is reached.
DiagnosticSequenceCount	SINT	Diagnostic counter. The value increments each time a distinct diagnostic condition is detected, and again when the condition transitions from detected to not detected. Set to zero by product reset or power cycle. Wraps from 255 (-1) to 1 skipping 0.	-128 to +127 The value of 0 is skipped except during device power-up.
Slave	AB:5000_ModbusSlave_Channel:I:1	Modbus Slave produce data.

Device-defined data type: AB:5000_ModbusSlave_Channel:I:0
Name	Type	Definition	Valid Values
Fault	BOOL	Indicates that channel data is inaccurate and is not trusted for use in the application.	0 = Good 1 = Bad, causing fault Tip: If set to 1, troubleshoot the device to correct the cause of the inaccuracy. Once the condition is removed, this is automatically reset to 0.
Uncertain	BOOL	Indicates that the channel data may be inaccurate, but the degree of inaccuracy is unknown.	0 = Good data 1 = Uncertain data Tip: If set to 1, troubleshoot the device to correct the cause of the inaccuracy. Once the condition is removed, this is automatically reset to 0.
CRC_LRCError	BOOL	Indicates if a CRC (LRC) Error occurred.	0 = Non-occurrence 1 = Occurrence
ParityError	BOOL	Indicates if a parity error occurred.	0 = Non-occurrence 1 = Occurrence
IllegalDataAddress	BOOL	Indicates if the request is out of Modbus Register Address.	0 = Non-occurrence 1 = Occurrence
FramingError	BOOL	Indicates if a framing error occurred.	0 = Non-occurrence 1 = Occurrence
BufferOverRun	BOOL	Indicates if a buffer overrun occurred.	0 = Non-occurrence 1 = Occurrence
SequenceNumberAck	INT	Acknowledges the sequence number.	-32768 to +32767
MasterUpdateCount	INT	Any Modbus change updates the count.	-32768 to +32767
HoldingRegister	INT[100]	The Modbus Holding Register value.	-32768 to +32767
Coil	SINT[16]	The Modbus Coil value.	-128 to +127
