HYPER Lab (Customer) asked a question.
According to the Lakeshore Manual from section 6.4:
The Ethernet interface provides a means of connecting the Model 336 to an Ethernet
based computer network. Ethernet networks provide the ability to communicate
across large distances, often using existing equipment (the internet, pre-existing
local networks). The Ethernet interface of the Model 336 provides the ability to use
TCP socket connections (section 6.4.3) to send commands and queries to the instrument
using the common command set detailed in section 6.6.
I know how to set the Lakeshore's static IP address, and what TCP port number it is (7777). I also know that it expects a query to look like :
So far I've set a static IP on the P2K so that it's on the same network as the Lakeshore, and connected them both via switch. I have tried programming many different rungs on the P2K side and have gotten nowhere. I'm not even sure that I'm properly sending any messages, and if I am, if they are being returned.
How should I program the P2K to work with this device?
Thanks for the help!
Read thru the manual for this device and have a few questions:
https://www.lakeshore.com/docs/default-source/product-downloads/336_manual0ebc9b06cbbb456491c65cf1337983e4.pdf?sfvrsn=2e8633a3_1
1.) Does this communicate to the plc via Modbus or EtherNet/IP protocol?
2.) It looks like you have to send it a string command for various functions?
Post a couple screenshots of your code or attached your .adpro file for others to review to see what you have programmed up to this point.
Without reading the manual it looks like you need a custom protocol over Ethernet CPOE instruction. I do not have a lake shore 336 but do have a p1000 talking to a p1am with a CPOE instruction and it dose work well.
