11 Programming
The development of application programs (Pluto PLC program) is made with a standard
Personal Computer using a specially developed software Pluto Manager. Communication
between the PC and the Pluto is made via the PC Com Port or USB port. The link facilitates
program down loading and monitoring of inputs, outputs, memory, timers, etc. with the PC “on
line”.
See separate programming manual for further information.
11.1 Self programming by exchange of Pluto
In applications with several Pluto units connected together with the Pluto CAN bus, it is
possible to exchange a unit and let it self load PLC program from another Pluto on the bus.
This is possible since in a program project with at least two Pluto units, all of them are loaded
with the same program file and this file has program for all units.
The following conditions are required:
- The new Pluto must be empty of PLC program (showing Er20).
(Pluto O2: Error LED On with short off periods (1200/80 ms))
- The new Pluto must be member in a Pluto program project.
- The IDFIX must NOT be exchanged. (Note that the connector blocks are detachable)
- For Pluto AS-i the IDFIX must be of type “IDFIX-DATA” or “IDFIX-PROG”. (Otherwise the
“Teach safety codes” procedure has to be performed as well.)
Procedure:
- Switch off power and exchange Pluto.
- Switch power on and after a few seconds the display shall show Er20 (empty).
(Pluto O2: Error LED On with short off periods (1200/80 ms))
- Press the “K” button in the Pluto front in 3 seconds until the display flashes “Lo”.
(Pluto O2: Error LED Flashes (320/320 ms))
- Release the “K” button and press it immediately one more time.
The display shall show steady “Lo”.
(Pluto O2: Run LED shall be On)
- Now the self programming has started. “K” button can be released, and when it is finished
Pluto starts to run automatically.
If flashing “Lo” doesn’t appear (Pluto O2: Run LED shall be On):
- Check the CAN bus connection.
- Check that the IDFIX is connected and that it is not changed to another with other number.
- Check that the Pluto really was member in same program project as the other on the Pluto
bus.
