Switch_Parameters Parameter
The AOI requests additional information from the switch as needed by a faceplate display (and
when started). This includes the CIP Identity object, the CIP TCP/IP object, an instance of the
CIP Ethernet Link object, and the NTRON Switch object.
The following RSLogix 5000 screenshot shows a top level view of some of the AOI
“Switch_Parameters” structure:
N228Params.Generic_Inputs is a generic view of the assembly data from a switch.
2.6
Explicit Messaging Options
To direct the AOI to gather this information (via explicit messaging) for other purposes
(example: not using faceplates), use the following members of the N228Params.Control tag:
Name
Data Type
Description
Selected_Port
INT
Use this member to read Ethernet Link object for one port. To
read more than one port, use Read_Port_Mask. Set by the
faceplate. Port data is copied to the
UDT_NTRON_CIP_DATA_v0 data type.
Request_Data
BOOL
0 - explicit messaging is disabled; 1 - explicit messaging is
enabled
Read_Port_Mask
DINT
Set bit n to read ethernet link object for port n+1
Explicit_Messaging_Timer
_Reset
DINT
Used to control time between each MSG call to read CIP
Identity object, TCPIP object, N-TRON object, and selected
Ethernet Link objects. Minimum is 200 ms. Default is 1000
ms.
Sample ladder logic rungs are available that show how to control explicit messaging.
2.7
Troubleshooting
Module Fault (Code 16#0315) Connection Request Error: Invalid segment type.
This error occurs when the assembly information specified for the Generic Ethernet Module does
not match the assembly information on the N-Tron switch.
