EtherNet/IP Implicit I/O Connections
Use the EIP Configuration dialogs to configure EtherNet/IP connections for the HART analog I/O module. You can configure the module for the following types of implicit I/O connections:
Configuring EIP Connections
The following parameters can be configured for an EtherNet/IP connection
Parameter
Description
RPI
The refresh period for this connection. This parameter should be set to a value from 20...1000 ms. Default = 20 ms.
Input T->O
Input size
(read-only) The number of bytes reserved for input data. The number is calculated by the DTM, based on the settings entered in the Process Data page. The default value depends on the module:
  • BMEAHI0812 = 140 bytes
  • BMEAHO0412 = 72 bytes
NOTE: Control Expert reserves input data in increments of 2 bytes (1 word).
Input mode
The transmission type:
  • Point to point: Transmission from adapter to scanner.
  • Multicast: Transmission from a scanner to a multicast IP address (default).
NOTE: An Exclusive Owner connection can be either point to point or multicast. A Listen Only connection is multicast.
Input type
Ethernet packet type – fixed or variable length – to be transmitted. Only fixed-length packets are supported.
Input priority
The transmission priority. Values can include:
  • Scheduled (default)
  • Low
  • High
Input trigger
The transmission trigger. Values can include:
  • Cyclic (default)
  • Change of State
Output O->T
NOTE: Output group parameters are configured only for Exclusive Owner connections. Listen Only connections do not send output.
Output size
(read-only) The number of bytes reserved for output data. The number is calculated by the DTM, based on the settings entered in the Process Data page. The default value for both the BMEAHI0812 and the BMEAHO0412 is 1 byte.
NOTE: Control Expert reserves output data in increments of 2 bytes (1 word).
Output mode
The transmission type. For output transmissions over Exclusive Owner connections, only Point to point is supported.
Output type
Ethernet packet type – fixed or variable length – to be transmitted. Only fixed length packets are supported.
Output priority
The transmission priority. Values can include:
  • Scheduled (default)
  • Low
  • High
