I would like to know if there is a product that could be used as a Point I/O (like the Allen Bradley Points I/O)
I am using this EPIC processor that must activate more than 30 valves that are like 30 feet away from the device. Another EPIC will not be the best solution. I am looking for this Point I/O so I can communicate with them through ethernet IP (or similar).
30 feet away? Why don’t you just run them off an IO module in the EPIC?
You can actually use I/O such as the 1734 Point I/O with the groov EPIC, if you are using Codesys and the Codesys Ethernet/IP Scanner SL Module. Codesys has an example configuration using the 1734 to help you.
There may be some point style I/O out there that speaks other protocols, such as modbus, then they would work with either PAC Control or Codesys.
It would be easier to run a single Ethernet cable than all those required to power and operate the valves.
I will check them. Thank you
Why not use a SNAP IO rack?
I wrote it wrong. The valves would be 300 feet away. Is there a way to use the 1734 Point I/O with PAC Control?
SNAP Pac and EPIC controllers must be installed with the I/O modules and they would not be used for the strategy. I am trying to run a single ethernet cable to the main controller.
It does not matter if its an EPIC or a SNAP at the valve end of the single Ethernet drop.
Both can be remote I/O to a PAC Control strategy running at the main controller.
You don’t need to run a strategy at the valves, but I think you should consider it. What happens if the Ethernet cable breaks? If you run a strategy at the valves, it can ‘safe’ the valves if communication is lost.
Thank you,
I will consider it. I am still trying to find the best option.
