I am doing some project work in a plant with older equipment which will NOT be updated. They will buy a new line in the near future so are using me for some mods for the time being.
One line has 4 Plc's on a DH+ network which also hooks into Channel B of a DHRIO card in a 2nd line's Controllogix Plc so I.T. can pull tags and we can also go online wirelessly.
The line in question has 2 x Plc 5 and 2 x Slc 5/04 processors. The 2 x Plc 5 and 1 of the Slc 5/04 talk with an old PV1200 which I am replacing with a spare 1400e in the near future.
The PV1200 is RIO and is connected to one of the Plc 5 ports with the 2nd port (DH+) going out to the other Plc's/Slc.
So, the Panelview is talking to the processors via RIO then DH+ via what must be an integral DHRIO in the Plc 5?
I am trying to get the 2nd Slc 5/04 to talk with the panelview (or the future 1400e) but am finding it difficult to figure out how to do so.
The Plc 5's are using block transfers but the present Slc 5/04 does not and I do not see any Messaging logic (I haven't worked with Messaging but I have with BT's years ago).
I have no idea how the present Slc 5/04 is talking to the panelview but it does have some Integers for temperature selection and indicating as well as a couple of input bits.
Any help appreciated!
