Number of Data Words/Data Bytes Dependent on the type of communication mode used on port 2/3 of the module, this value will be interpreted as number of data words or number of data bytes. In any communication mode except for "3" (MOBY-I/E) it means data words. This value defines whether a job will be carried out with or without subsequent telegram. For jobs without subsequent telegram the value will be 1 ... 64 words (1 … 128 bytes), and for jobs with subsequent telegram(s) it will be 65 ... 256 words (129 … 512 bytes). Coordination Byte 9/10 3964R with RK512 send jobs offer the possibility of entering so called coordination bytes (byte 9 and 10 in the RK512 telegram header). Otherwise to be set to "0".
Receive Jobs
To receive jobs from a CP only, no additional parameterization is necessary. The user data received is stored in a file in the SLC processor. The following table shows an example of the data stored in RECVHDR2 in case of a DB-Send from a CP. The CP is connected to port 2.The send message can request a data type of Data Words (44h) or Marker (4Dh). If the value is 0 (zero), then data words is used.The user data is copied to RECVMSG2. This is the file you should operate with. For port 3, which is similar to port 2, the file for storing the user data received is called RECVMSG3. 2.3.4 Send Jobs To send a job to a CP, the next step is to define the appropriate header for the job.
Job Processing
Both ports can be used independently from each other (multi tasking). A possible initialization conflict will be solved as follows: The MVI46-3964R retries the sending of the 3964R start character (STX) 3 times and waits for the CP to send the 3964R acknowledge (DLE). If the CP does not send the acknowledge as expected the communication will fail and has to be restarted. To send with 3964R without RK512 to a CP (identifier 00FFhex), the values for DB, DW and the coordination bytes will be ignored and can be set to "0". The next step is to copy the user data into the appropriate files of the SLC processor.
