| BK9500 - Bus Coupler for USB |
Local process image
The default setting is for all the connected Bus Terminals to be assigned to the local process image. Mapping within the Bus Terminal coupler is carried out according to the following rule:
First all the byte-oriented (analog) Bus Terminals, in the sequence in which they are inserted, followed by the bit-oriented (digital) Bus Terminals, rounded up to a whole byte.
Sample
The BK9500 is connected to a PC over the USB. The address of the coupler is set to 1. The following terminals are attached to the coupler (the number of the bits that are mapped is given in brackets):
Location | Terminal on the rail |
|---|---|
POS00 | BK9500 |
POS01 | KL1002 (2 input bits) |
POS02 | KL1002 (2 input bits) |
POS03 | KL1002 (2 input bits) |
POS04 | KL1114 (4 input bits) |
POS05 | KL1114 (4 input bits) |
POS06 | KL3002 (2 x 16 input bits) |
POS07 | KL9200 (-) |
POS08 | KL2012 (2 output bits) |
POS09 | KL2012 (2 output bits) |
POS10 | KL2012 (2 output bits) |
POS11 | KL2012 (2 output bits) |
POS12 | KL4002 (2 x 16 output bits) |
POS13 | KL9010 (-) |
It follows that the Bus Coupler's process image appears as indicated below:
