Hello all,
our company decided to implement some Pick to light(poka yoke) system.
There will be a lot of inputs/outputs all around the floor connected to it, so we decided to use some industrial buses (TURCK - TBEN-L1-16DXP) connected to PLC (FX3G with ENET-502 card)
but there is noone with needed experience with modbus tcp, so there i a lot of confusion and as someone responsible for project im starting to feel a little bit overhelmed since my experience with industry comunication protocols i very close to zero
1) do i need switch to make it work? (PLC <> switch <> buses) or can i connect buses directly to PLC?
2) Ive read manuals about modbus, but im somehow confused with master/slave, server/client terminology...
master/slave is used for serial link?
server/client - it looks to me like my controling plc should be client and buses servers :/ but it doesnt make sense to me
3) is there some comprehensive flowchart of how modbus message are formed, send, recieved and responded? (like what conditions have to be met to have succesful comunication between PLC and BUS?)
Thanks in advance to everyone willing to help
