javiquez Posted March 24, 2020 Report Share Posted March 24, 2020 I need to create a network with 37 machines and collect some information in each of them by mean HMI units.Besides I need to introduce 4 different data in 4 registers in each machine. All units must be networked to create a log register about the individual operation in a common place as a manager computer. Each control unit will receive information from a Modbus Current sensor installed in each machine telling me the their state (on/off). This is used to avoid invasive electrical modification for any machine. I was thinking in a 5.3 to 7 inch screen size units. I require IP66 protection. I think I need two comm ports RS485 for Modbus communication, one for sensor and other for the network section. I am attaching a single line diagram. What will be the best and cheap option using Unitronics units and what I need (HMI, CPU, Comm ports? I will be happy with comments and suggestions from the forum members.

TozoM8 Posted March 24, 2020 Report Share Posted March 24, 2020 I have a couple different size vision series sending data back and fort with UniCan. Works great. I think you can go up to 62 units. Quote Link to comment Share on other sites More sharing options...
