V1210 MASTER, V130 SLAVE , best way to communicate them?

[lauraz]

Hello,

 

Wich is the best way to communicate a V1210 Master with V130 Slave? With modbus or with the unitronics protocol?

 

THANKS for your comments.

Hi Laura,

For a start, there isn't really a "best" way. Both protocols are doing the same job, on the same physical layers, in (approx.) the same speed.

Before making a decision, more information is needed:

What type of communication are you using (serial/Ethernet)?

what is the distance between the PLC's?

Are there any other devices connected to this network?

 

If using Ethernet for communication, it is easier (on my opinion) to define the PLC Datacom function blocks for data transfer.

If using serial communication, Modbus is the fastest protocol to set up in your system.
