My thought is you would want to get the data written somewhere (local PC file perhaps) as FAST as possible.
Then you could have a background app that's writing the transactions to the iSeries at a slower pace unless you need the iSeries app to have real-time interaction.
If it's TCP/IP based you could use Sockets programming.
If you decide to outsource any of the development let me know. We have written similar apps before but have not worked with your particular PLC.
Usually the idea is to offload the PLC the device transactions as quickly as possible.
Let us know the ultimate outcome.

subject: Mitsubishi PLC interface to AS400 Data Tables
Hi All,
One of our assembly divisions recently acquired a Mitsubishi PLC module that they would like to connect to our AS400. They sent me the manual and it is an absolute nightmare to try and understand how the two systems are supposed to communicate. There's a lot of talk on triggers, local transports, etc., etc. It looks like a really powerful system, but I am having a very hard time interpreting what needs to be done from the manual.
The model number of the interface they purchased is QJ71MES96IT. They also purchased the transport/database module part number MESITTRNSDB2 to compliment the MES IT interface.
So my question is (and yes, it is a very broad question as I really do not have a starting point) - how do I get the data from the PLC into an AS400 table? Does anyone have any experience with this module that can help me understand how this is accomplished?
Any ideas, or resources I might be able to access to help me understand?
Thankee-sai!
