address of the register you wish to access. The two most significant

digits will be added automatically with a value that depends on whether

you click the Read button or the Write button.

Value This field is used to read or write values for the register specified in the

of the selected radio button or an error will result. If an error occurs, its

description will be displayed in this field.

Status This read-only field reports the status of the most recent Modbus action.

If your attempt to read or write a register is successful, the reported

status is "Success" and the Value field displays the value in question. If

the attempt to access a register is unsuccessful, the Value field reports

the type of error that was generated.

The five radio buttons on the left specify which number format is displayed in the Value

field. The choices are:

0X:Coil Use this button if the addressed device is a Binary Output that has only two

possible state values (0 or 1) — as is the case for a coil.

1X:Coil Use this button if the addressed device is a Binary Input that has only two

possible state values (0 or 1) — as is the case for a coil.

4X:16-Bit This button displays the specified 16-bit register value in raw-number format.

4X:32-Bit This button displays the specified 32-bit value of a register pair in raw-number

format and enables the four radio buttons on the right (see below).

Scaled If the specified register represents a BAS Remote I/O point, engineering units

can be displayed by selecting this button. But if the register is not one of the

BAS Remote I/O points, an error will result.

The four radio buttons on the right specify the number format of a 32-bit value. The

choices are:

Integer This button specifies a whole value with no fractional content.

Float This button specifies a single-precision floating point value.

LOW:HIGH This specifies Little Endian format whereby the low word occupies the

base register and the high word occupies the next-higher register.

HIGH:LOW This specifies Big Endian format whereby the high word occupies the

base register and the low word occupies the next-higher register.

Read and Write buttons Clicking one of these buttons causes the specified action to occur.
