Job Identifier

The job identifiers are defined as follows:

Send jobs to a CP:

Job: Identifier:

3964R with RK512: DB-SEND to CP 0041hex

3964R with RK512: DB-FETCH to CP 0045hex

The MVI56-S3964R receives jobs from a CP automatically without extra

parameterization. To differentiate the header data the

MVI56-S3964R adds a

header to the user data received and transfers it to the ControlLogix processor.

Receive jobs from a CP

Job: Identifier:

3964R with RK512: DB-SEND from CP 1141hex

3964R with RK512: DB-FETCH from CP 1145hex

Data Block (DB)

Number of the data block. This data block must exist in the communication

partner (3964R with RK512 only, otherwise to be set to "0").

Data Word (DW)

Number of the data word in the selected data block. The selected data block

must contain this number (3964R with RK512 only, otherwise to be set to "0").

Number of Data Words/Data Bytes

Dependent on the type of communication mode used on port 1/2 of the module,

this value will be interpreted as number of 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".

Data Type

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.

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 ControlLogix processor.

The following table shows an example of the data

stored in HeaderCom1 in case

of a DB-Send from a CP. The CP is connected to port 1.
