Hi everyone,
I'm working in automation department, I have some questions regarding the Ethernet Connection.
Is multiple switches can reduce the traffic load?
My connection PLC to RFID Controllers.
four PLC units -- one 16ports Switch -- eight 4port gateways -- thirty two RF controllers
By this connection, twelve ports have been used in the switch and another two ports connected to previous and next PLC panel.
The result is RF controllers return no value frequently, about 10% rate.
----------------------------------------------------------------------
I added in another switch, the connection become one switch connected to twenty four RF controllers and another switch connected to eight RF controllers, two PLC panels.
three PLC units -- one switch -- six gateway -- twenty eight RF controllers
one PLC unit -- one switch -- two gateway -- eight RF controllers
-- two panels
The result is RF controllers return no value rate become 0%.
----------------------------------------------------------------------
Is the traffic load problem? I have checked the connection between panels, there is no loop.
