Data Transmittion (between AC800M - AC700F, AC800M - AC500)
Dear colleagues
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.

hello,
What amount/volume of data you want to transmit and at what transmission rate?
Best option would be OPC for bulk/large data transactions. If you have less data you can use Modbus rtu between AC 800M and AC 700F/AC500 controllers.

Right-click on that small red or black pixels in the left under the question "How to transmit data between PLCs? How to do?" and select "Save picture as...". There are AC500 and AC800 connected to the same control network, AC800 and AC700 connected via Modbus.

Not able to retrieve picture, may be because of browser IE.

You need right-click very precious, exactly on pixel. It works in IE9 at least. Here's that picture:
