N.B.: Use of 32-bit process data.
For configuration of 2-word (32-bit) parameter read/write, use 2 consecutive arrays in
12-21 and 12-22, like [2]+[3], [4]+[5], [6]+[7] etc.
Read/write of 2-word values in arrays like: [3]+[4], [5]+[6], [7]+[8] is not possible.

EtherNet/IP connections

The MCA121 option supports the following CIP connections:
Class 1 connection
I/O connection using TCP transport.
Maximum one Class 1 connection is supported. Several listen only connection can be established if
multicast is selected as Transport type.
This type of connection is used for cyclic I/O and Change-Of-State connections. The connection is
established with a Forward Open command, containing theses information:
Transport Type:
Specified for both directions: Originator-to-Target / Target-to-Originator.
- Point to Point
- Multicast
Data Size:
Specified (in bytes) for both directions: Originator -> Target / Target -> Originator.
The data-size depends on the assembly-instance chosen in: Destination.
Packet Rate:
Specified (in milliseconds) for both directions: Originator -> Target / Target -> Originator.
Minimum packet rate supported: 1 ms
Production inhibit timeout:
Specifies (in milliseconds) the timeout-time for both directions.
Trigger:
Selects the transport trigger type:
- Cyclic (Data are transmitted cyclically as polled I/O).
- Change Of State (Data are transmitted on Change of State only. COS-filters are set-up in par.
12-38 COS Filters)
Connection points:
Specified for both directions: Originator -> Target / Target -> Originator.
