Project transfer
There are the following possibilities for project transfer into the CPU:
•
Transfer via MPI
•
Transfer via MMC
•
Transfer via integrated Ethernet PG/OP channel (Initialization necessary)
The MPI programming cables are available at VIPA in different variants.
The deployment of the cables is identical. The cables provide a bus
enabled RS485 plug for the MPI jack of the CPU and a RS232 res. USB
plug for the PC.
Due to the RS485 connection you may plug the MPI programming cables
directly to an already plugged MPI plug on the MPI jack. Every bus
participant identifies itself at the bus with an unique MPI address, in the
course of which the address 0 is reserved for programming devices. The
structure of a MPI net is in the principal identical with the structure of a
1.5MBaud Profibus net. I.e. the same rules are valid and you use the same
components for the build-up. The single participants are connected with
each other via bus interface plugs and Profibus cables. Your SC CPU
supports transfer rates of up to 1.5MBaud. Per default the MPI net runs
with 187.5kBaud. VIPA CPUs are delivered with MPI address 2.
A cable has to be terminated with its surge impedance. For this you switch
on the terminating resistor at the first and the last participant of a network
or a segment.
Please make sure that the participants with the activated terminating
resistors are always provided with voltage during start-up and operation.
