Hi. I have 3 units of Siemens LOGO PLCs, 3 units of Data acquisition devices (communicating with PLCs via MODBUS-TCP) and 1 RPi 4 (commuicating with all the LOGO PLCs) in my network. Currently, I am using several s7 in node in Single variable mode in my nodered flow.
If I switch to one s7 in node in All variables mode, will I notice huge reduction in my network traffic? I notice network communication issues between data acquisition devices and plcs, and I would like to know, if it is efficient to switch to all variable mode.
Will communication happen in an optimized way in All variable mode compared to Single variable mode?
Thanks in advance.
