The individual areas of DB TestCopyData
The DB for the TestCopy function is divided into several different areas:
● Area 1: DBB 0 ... DBB28
User interface for setting the TestCopy operating mode and displaying any errors.
This user interface in turn is divided into the following areas:
– Area 1.1: DBB 1 ... DBB 13:
Filter settings for RecvCopy function and number of counted received messages.
– Area 1.2: DBB 15 ... DBB 27:
Filter settings for SendCopy function and number of counted sent messages.
● Area 2: DBB 29 ... DBB 39:
Internal management pointers
● Area 3: DBB 40 ... DBB xxxx:
Buffer area for storing messages that match the filter criteria; the buffer area must be
configured as an array [0...xxxx] of WORD.
Structure of a copied message block
A message block can contain several messages. The messages are stored in DB
TestCopyData according to the following rules:
1. The first entry indicates the time difference in milliseconds (7 decade BCD plus sign)
since the last selection of an operating mode > 0.
2. This is followed by a separation sign AAAA for sent messages, EEEE for received
messages.
3. Storage of the first message from the message block.
4. Separation sign AAAA, or EEEE:
5. Storage of the last message from the message block.
6. Block end ID FFFF.
Example
All received messages will be stored in DB TestCopyData. Communication is implemented
using X blocks, i.e. a max. of 76 bytes per receive block. The receive buffer of the
XComData DB is the source for FC TestCopy. The current receive block contains 3
messages.
