MbusDataTableInterfacereadEnronRegistersTable Method

Implement this function only if your slave device has to process register ranges as Daniel/ENRON 32-bit registers.

Namespace:  FieldTalk.Modbus.Slave
Assembly:  FieldTalk.Modbus.Slave (in FieldTalk.Modbus.Slave.dll) Version: 2.11.0-eval+eb1ecbe71c969eff5d7c05d58da16dade0474678
Syntax
Copy
protected virtual bool readEnronRegistersTable(
	int startRef,
	int[] regArr
)

Parameters

startRef
Type: SystemInt32
Start register (Range: 1 - 65536)
regArr
Type: SystemInt32
Buffer which has to be filled with the reply data (Length: 0 - 62)

Return Value

Type: Boolean
true indicates a successful access and that valid reply data is contained in regArr. The Server Engine will reply the data passed in regArr to the master using the Daniel/ENRON frame format.

false indicates that the requested range is not to be processed using the Daniel/ENRON frame format. A subsequent call to readHoldingRegistersTable() will be made to process the range in standard Modbus frame format.

Remarks
If a register range is processed as Daniel/ENRON register then this range is not available as normal Holding Register range.

Required: Yes

Default Implementation: Returns 0 which indicates that the requested register range is processed as standard Modbus registers by a subsequent call to readHoldingRegistersTable().

Note: Daniel/ENRON is a prorietary 32-bit format which uses a non-standard Modbus frame and not understood by most master devices.
