Modbus (RTU) Serial Address Definitions 81

Magnetek Address

Descriptions

The following table provides the general ranges of data available for a

Magnetek GPD 515 Drive. Consult the Magnetek Modbus RTU

Technical Manual, part number TM4025, for information on how

specific drive parameters can be accessed using Modbus RTU

addressing. In all cases, the letter H (used to signify Hex addressing)

should precede the desired address.

Default data types for dynamically defined tags are shown in bold

where appropriate.

Addressing Example

To access the drive’s Operation Status (address 02BH), enter the

following address in you client application.

H4002B

Important Notes

• When adding a Magnetek device to your OPC Server project,

make sure the setting Use Zero Based Addressing is not checked

(page 27). If this parameter is not set correctly, the Modbus RTU

driver will offset all of your Magnetek addresses by 1.

• Arrays are supported for holding register locations for all data

types except boolean. There are two methods of addressing an

array. Examples are given using holding register locations.

4xxx [rows] [cols]

4xxx [cols] - assumes rows is equal to 1

• Rows multiplied by cols cannot exceed the block size that has

been assigned to the device for the register type.
