A–12 LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL
LM10 AND GE FANUC 90-30 WITH DEVICENET™ CHAPTER A:
• Rung 3 has a Block Move word, 3 blocks.
• Rung 4 has the COMMREQ ladder instruction.
Refer to Chapter 5: Communications for a complete description of each word.
In the ladder below, the Trip Class is read from the slave (LM10 device) MAC ID 1. Some key
word settings to obtain the LM10 Trip Class from Slave 1 are shown below:
• Word 11: Slave MAC ID setting (for example, 1)
• Word 13: Get Attribute (for example, 16#0E to read)
• Word 14: Object Class to which the Request is directed (for example, 16#64)
• Word 15: Instance of Object Class (for example, 1)
• Word 17: Attribute (for example, 16#2F00)
To get parameters under the access type history, Word 13 will be 16#32.
To read the operating voltage, change following words:
• Word 13: 16#32
• Word 17: 16#4500
To view the parameters in a Reference View Table, create a new Reference Table then add
addresses %R00250 and %R00256. The control voltage will be displayed in address
%R00256. Change the display format to unsigned decimal.
To view the slave number of slaves connected to master card, add address %I00001 to the
new reference table. Now, address %I00002 will read “1”, since the LM10 is connected to
the master as slave 1 (MAC ID 1).
Also in the Reference View Table, add the input register %I00xx and output register
%Q000xx for Connection 1 and Connection 2, respectively.
