MicroLogix 1100 and 1400
Explicit Messaging MicroLogix 1100 and 1400 controllers can read and write information to and
from the E1 Plus EtherNet/IP Side Mount Module using Explicit Messaging and
the Assembly Object. RSLogix 500 Version 8.10 or higher is required to
configure EtherNet/IP explicit messaging with these controllers.
An example of a MicroLogix 1100 using the MSG instruction to read all of the
motor diagnostic data from the E1 Plus EtherNet/IP Side Mount Module is
shown below.
1. Write the appropriate ladder logic to periodically execute a MSG
instruction for the MicroLogix controller.
2. Configure General tab in the MSG instruction with the following
parameters:
• Channel: 1 (Integral) - the Ethernet port on the processor
• Communication Command: CIP Generic
• Data Table Address: the location to store the information
• Size in Bytes: 22 – assembly 111 consists of 22 bytes of information
• MultiHop: Yes
• Service: Read Assembly – to read an input assembly
