Hi Friends,
I have an upcoming project were I need 20 pcs of ModBus TCP Clients / AOI. to control 10 devices
I use 20 transactions to control 10 devices, however some devices have SUNSPEC registers spread all over the address range, that we need to access - there for using 10 transaction / 2 MBTCP clients(AOI) for one unit to control.
Is this high number something that should be kept on an external HW instead, such as HMS or similar Modbus extender?
Reason for have it on PLS is that it goes way quicker to just fill in the correct transactions during commissioning (some trial and error)
Update of incoming values is ok to be set to 1000mS
PLC is L33ER Compact Logix, please feel free to share your knowledge on the topic.
Would like to hear comments here
