Data Transmittion (between AC800M - AC700F, AC800M - AC500)
Currently, we’re performing Water Treatment Plant with 800xA IT software of ABB. Currently we have some problems while we’re programming system.
Please advise us for data transmittion between:
1. AC800M of AC700F (describe as pic)
2. AC800M of AC500 (describe as pic)How to transmit data between PLCs? How to do?
We looking forward your respond soon, thank so much for your cooperation

for option 1. AC800M y Ac800F , Ac800M has one modbus serial port that you can use, but Ac800f, you will need one serial module if you want to connect via modbus.
also you can use OPC but in this case, you need to use something in the middle because both are OPC server, so you need one device or software that connect two OPC servers, it exist.
for option 2, Ac800M and Ac500, the cheaper option is Modbus serial, because Ac800m has one serial port and it can be modbus master, Ac500 has two serial ports and it can be modbus slave.
also you can use OPC but in this case, but equal both are OPC servers.
