Commands

Commands are used by the primary device to send and receive data from the interface as integer or floating-point data. The primary sends eight bytes in the output format to write commands to the indicator and reads eight bytes in the input format to read data from the indicator.
Decimal Point Handling
Integer commands return no decimal point information to the primary.
For example, a value of 750.1 displayed on the indicator is returned to the primary as 7501. Floating point commands support decimal point information with no special handling.

Output Data Format

To perform a command, the primary uses the output command format to send four 16-bit words to the interface. These four words contain the command and the necessary parameters to execute it. The output command format is shown in Table 4-1.

Table   4-1. 1280 Output Data Format

Byte 1
Byte 2| Parameter
Byte 3
Byte 4| Value (MSW)
Byte 5
Byte 6| Value (LSW)
Byte 7

NOTE: See Section 4.1.1 on page 15 for BYTE swapping parameters.
A lockout feature, incorporated into the indicator receive mechanism, looks for change in
the output format data to prevent inundation by the same command.
See affected commands noted in Table 4-2 on page 13 with an (*).
Repeated commands must be separated by any other valid command/parameter/value combination.

Parameter Value
In communication with a multi-scale indicator, the scale number is sent in the second word of the output command format. Zero (0) represents the current scale. Certain commands require a parameter other than a scale number, such as a slot number, setpoint number, or other selection parameter. See the command descriptions in Section 4.3 on page 19 for specific command requirements.

Value
The third and fourth words of the output format are used to pass value data on certain commands. Values entered in these words are treated as unsigned long integers or floating-point values, depending on the command.

Command Number
The number representing the indicator command is sent in the first word.
Table 4-2 lists the commands that can be specified for indicators. Some commands may not be available on all indicators.

Table 4-2. Remote Commands

BYTE Swapping

NOTE: See the Ports Menu in the indicator manual.

The indicator sends and receives data in integer format.
The standard format is as follows for all input and output values:
High BYTE – Low BYTE
If the indicator FLDBUS/SWAP parameter is set to YES, then the BYTE order changes to:
Low BYTE – High BYTE
Example: If the weight on the scale reads 10 lbs and a value of 2560 is displayed in the PLC, either swap the BYTES in the PLC or change the SWAP parameter to YES.

Input Data Format

The interface returns data and status information to the primary as four 16-bit words in response to a command. The input command format is shown in Table 4-3.
The value type can be set for commands not specifying integer or floating point data by sending the command 0x000 to specify integer data, or sending command 0x100 to specify floating-point data. The value type is returned in the status word (bit 14) of the input format.

Table 4-3. 1280 Input Data Format

Byte 1
Byte 2| Status
Byte 3
Byte 4| Value (MSW)
Byte 5
Byte 6| Value (LSW)
Byte 7

NOTE : See Section 4.1.1 for BYTE swapping parameters.

Command Number

The first word echoes the command number. If the command fails or is not recognized, the negative of the command number is returned to signal the error.

Status Data

Indicator status data is returned in the second word (Table 4-4). Batch commands return batch status in place of the low byte (Table 4-5 on page 17). Setpoint commands return batch status in the low byte of the status word and the setpoint number in the high byte.

• PLC command failed to execute
• No configuration has taken place
• Scale parameter is out of range
• Print error has occurred
• Load error has occurred
• Memory error has occurred
• Analog to digital converter error
• Tare error

Value

Weight data is returned to the primary in the third and fourth words of the input command format, depending on the command and the value type. The weight data returned is the displayed weight after the command is executed, unless the command specifies otherwise.
A negative value is returned in the two’s compliment format.

Setting a Float Value

Setting a float value in a setpoint requires the value to be sent in two separate integer values.
Most PLCs have a mechanism to take a float value and separate it into to integer values.
Example: The following must be sent in the output words to set the value of Setpoint #1 to 10000.

Command word = 304
Parameter word = 1
MSW = 17948
LSW = 16384

Reading a Float Value
When a float value is read it will be returned in two integers representing the float value.
The PLC must combine MSW and LSW integer values back into a float value.
Example: The following is returned in the input words if the weight on the
scale is 800.5.
Command Word = 288
Status word = Scale status
MSW= 17480
LSW = 8192
