MotionWorks IEC Hardware Configuration – 2013-03-26 60
1.9.4 Using an EtherNet/IP Scanner to Communicate to the
MPiec Controller as an Adapter
12 pre-configured instances are defined for input and output. The pre-
configured instances are listed below. Each instance can be enabled or
disabled individually based on application requirements.
The following diagram shows the groups with memory mappings from the
Global Variables sheet in MotionWorks IEC when all input and output
instances have been enabled in the MPiec Hardware Configuration.
Note: The exact byte size of the instance must be configured on the
Scanner side. (The entire 128-byte or 256-byte block must be transferred
even if less data is required.)
The controller will automatically respond to incoming EtherNet/IP
messages from Scanners requesting to read or write data of the pre-
defined instances.
Note: The scanner must configure both an input and output assembly. If
the application does not require any data from the MPiec controller, use
assembly 128 with a size of zero and set the "Use Run/Idle" checkbox to
satisfy this requirement.
