Description

Address

16-bit register address in hexadecimal. The address is the data used in the Modbus frame.

Register

16-bit register number in decimal. Register = Address + 1

No

Number of 16-bit registers that need to be read/written to access the complete information.

Function code

Codes of Modbus functions that can be used to read and/or write the register.

RW

Whether the data is read only (R) or read-write (RW).

X

Scale factor:

• A scale of 1 means that the value of the data is the right one with the unit indicated.

• A scale of 10 means that the data contains the value multiplied by 10. The actual value is therefore the value of the data divided by 10.

• A scale of 0.1 means that the data contains the value multiplied by 0.1. The actual value is therefore the value of the data multiplied by 10.

Unit

Unit of the value of the data.

Type

Coding data type (see Data Types table below).

Range

Range of permitted values for the parameter, usually a subset of what the format allows. For BITMAP data type, the content range does not exist.

Default Value

Default value for the parameter.

Svd

Value saved when the power supply to the TeSys Tera system is switched off:

• Y: the value of the data is saved.

• N: the value is lost.

Description

Information about the data and the restrictions that apply.
