Description
|
|---|---|
|
1
|
The slave station transmits event data to the PCMCIA card of the master station.
|
|
2
|
When the card receives the data, a bit from words %IWr.m.1.2 or %IWr.m.1.3 is initialized. Each bit of the input words is associated with a link address.
|
|
3
|
On detecting one of the bits, the application transmits a SEND_REQ communication function with code 16#82(read_generic_object) to the PCMCIA card of the master station for the data to be read.
