810D topology
On the 810D, the machine control panel, handheld unit and OP are connected to the MPI
(multipoint Interface) of the AS 300. The transmission rate in this configuration is 187.5
Kbps. The PLC operating system copies the incoming signals straight to the user interface
(e.g., input image) at the cycle control point.
Transfer to the VDI interface is performed, as on the 840D, by the user program or by a
standard routine of the basic program.
