Rockwell Automation MMCL Using the Mining, Mineral, and Cement Library (MMCL) in RSLogix 5000 Appli - Manual (Page 33)

Using the E3 Module 33
E3 Installation and Wiring
Refer to the E3 and E3 Plus Solid-State Overload Relay User Manual,
publication 193-UM002, for installation and wiring details.
System
The E3 Overload Relays provide for data exchange over the Network of
configurable Input and Output Assemblies. Inputs (Data from E3) are 8 Bytes
(4Words) and Outputs (Data to E3) are 1Byte.
Note: You can read more data out of the E3 then we have the possibility to
reach with explicit messaging. However this asynchronous messaging will
generate a high communication load at the processor.
Recommended Workflow
1. Configuration of the whole DeviceNet network related to a
DNB-Scanner Module. This is possible in Online or Offline Mode.
Remember to set the E3plus Parameter.
2. Use the DeviceNet Tag Generator to generate all Tags and Structures of
the DeviceNet Network.
3. Exchange all Data Types of E3 Data Tags which are created in the
previous step by the DeviceNet Tag Generator with common UDT,
E3_Inp and E3_Out, respectively.
4. Code programming in your application routine.
IMPORTANT
Do not use a MSG (explicit message) operation to get data
from the E3 Device.
