Exception Codes
Upon reception of any of the following exception codes,
datapoints of the EAGLE application will show "no response."
Table 8. Supported exception codes
exception code (hex) function
01 illegal function
02 illegal data address
03 illegal data value
04 slave device failure
05 acknowledge
06 slave device busy
Register Sizes
The following Register sizes are supported:
 16-bit Registers for Discrete inputs, Coils, Input Registers,
and Holding Registers
 32-bit Registers for Input Registers and Holding Registers.
Data Types
The following data types are supported:
 Discrete Inputs:
- BOOL
 Coils:
- BOOL
 Input Registers:
- BOOL
- INT16, UINT16
- INT32, UINT32
- FLOAT
 Holding Registers:
- BOOL
- INT16, UINT16
- INT32, UINT32
- FLOAT
- 32-bit floating points can be transmitted as two
consecutive 16-bit registers.
Byte and Word Order Transmission
 Most Significant Byte First (default)
 Lower Significant Byte First
 Most Significant Word first (default)
 Lower Significant Word first
Bit Unpack
The EAGLE allows direct reading of single bits of an Input
Register or of a Holding Register into a data-point.
In typical situations in which several different status bits of a
Modbus slave’s Register need to be read and linked into the
EAGLE application, this allows for very efficient application
engineering.
Number of Stop Bits
One and two stop bits are supported.
Error Checking Mode
Parity checking: No parity, even parity, odd parity.
Frame checking: Cyclical redundancy checking (CRC).
Life Check of Modbus Slaves
The EAGLE checks the Modbus every 15 seconds for lost
Modbus slave devices.
Message Response Timeout
20 msec ... 5000 msec.
Modbus Slaves Scan Cycle
The measurement cycle of all addressable Modbus slaves
depends upon the number of connected Modbus slaves and
the total number of mapped datapoints. The minimum
measurement cycle is 500 msec. This cycle time is based
upon the read cycle of the datapoint manager in the firmware.
Modbus Communication Failure Indication
As soon as the EAGLE runs an application which includes
Modbus points, it will try to communicate with the Modbus
devices based on the Modbus to datapoint mapping of the
application.
If a Modbus slave does not respond to a message from the
EAGLE controller, the message will be repeated two times. If
the Modbus slave does not respond to the two message
repeats either, the EAGLE will stall the messaging to this
Modbus slave for 15 seconds. After these 15 seconds, the
Modbus slave will be again addressed with the same two
repeats, if necessary. This cycle will be repeated endlessly.
If the EAGLE does not receive any response for a duration of
six (6) seconds, the System Alarm "MODB COMM ERROR"
will be issued.
