2 S5 928-CPU in same rack

pasimanninen · Feb 23, 2011

We upgrade s5 to s7 on cell factory packaking line and i have a little question.

One of the 32 bit input cards in weird. First 3 bytes belong to CPU1 and last byte belong to CPU2.

Where this tricky input method is described. Coordination card OB´s of course but how ??

In S7 hardware is possible describe only 4 bytes /card /CPU.

Of course i can change last byte operands for different operands in step7 program. But it makes more work.

Connection markers between 2 CPU in s5 bus is ok for me, but periphery with coordination card is weird

Each CPU keeps its own list of what it is to control in DB1 listing the inputs, outputs and IPC flags.

Special thanks Manglemender

Just now i realised why we dont need DB1 to program conversion S5 ---> S7. i just wondered why DB1 must left out before conversion to S7. Thank you

Glad it's making more sense. I see your location is Joensuu, a very nice place as I recall; I only passed through the airport going to and from Lieksa to commission a machine around 1991.
