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.
