PI Interface for Modbus Ethernet PLC 126.96.36.199
With this release, the PI Interface for Modbus Ethernet PLC is now available in two different options: a new read-only option and an update to the already-existing read-write option.
The read-only option is strongly recommended for installation if updates to the data source are not needed (that is, it does not allow output points). The read-only option provides the best defense against accidental or malicious changes to the control system because it cannot write to the data source.
The read-write option retains the ability to write data to the data source (using output points) and is an update to previous installations of this interface.
For more information on these two interface options and how to switch from the read-write option to the read-only option, please see the Read-only versus Read-write Interfaces FAQ document.
