Hints for the deployment of the MPI interface
The MP
2
I jack combines 2 interfaces in 1:
•
MP interface
•
RS232 interface
Please regard that the RS232 functionality is only available by using the
Green Cable from Advantech.
The MP interface provides the data transfer between CPUs and PCs. In a
bus communication you may transfer programs and data between the
CPUs interconnected via MPI.
Connecting a common MPI cable, the MPI jack supports the full MPI
functionality.
Important notes for the deployment of MPI cables!
Deploying MPI cables at the ADAM CPUs from Advantech, you have to
make sure that Pin 1 is not connected. This may cause transfer problems
and in some cases damage the CPU!
Especially Profibus cables from Siemens, like e.g. the 6XV1 830-1CH30,
must not be deployed at MP
2
I jack.
For damages caused by nonobservance of these notes and at improper
deployment, ADAM does not take liability!
For the serial data transfer from your PC, you normally need a MPI
transducer. Fortunately you may also use the "Green Cable" from
Advantech You can order this under the order no. ADAM-8950-0KB00.
The "Green Cable" supports a serial point-to-point connection for data
transfer via the MP
2
I jack exclusively for ADAM 8xxx CPUs.
Please regard the hints for the deployment of the "Green Cable" on the
following page.
