Hello,
I am new to the plc world and have been looking for plcs for an internship project. I have 70 modbus devices to control with a plc as the master/client. My customer would like to visualize the data online, with an hmi esque interface, control of plc is not required but viewing varaibles is. I have been looking at the Siemens s7-1200, but as their lead times are big in the US, and their web server examples didnt look all that modern I am looking for some more devices. The customer also specified they would not like a custom web host solution using any apis or mqtt.
Requirments are:
<2500 in price
rs-485 serial interface
Modbus RTU Communication support
Real time clock
Some sort of modern web hmi intergrated
Are there even plcs that can accomplish this with an HMI to the extent they would like, or should I start looking at hmi's, headless hmis, etc
