R5REQ Function Module5-2
5.2.1 Input Parameters
Parameter Att. Description
P0 W Data type
This parameter specifies the type of data range. A data area of 16 words
is reserved for each job for the protocol-specific parameters. Data modu-
les (44H), the data buffer (64H) and the data field (43H) can be used as
data ranges. The user must always reserve 16 words per job for the pa-
rameters which are specific to the job.
Parameter Att. Description
P1 W Data type attribute
If P0 specifies a data module as a data area, P1 indicates the data-
module number. In other cases P1 is meaningless and should be occu-
pied with FFFFH.
Permitted values are 0 - 255 and FFFFH.
Parameter Att. Description
P2 W Byte offset
The start address for the job parameters is specified in the selected data
area.
Parameter Att. Description
P3 W Job bit array JBA
Each of the 16 bits of this parameter refers to a block of job parameters in
the data range specified by P0 through P2. Comprising, as it were, a bina-
ry control panel with 16 switches, it has been termed job bit array (JBA).
Bit 0 to P3 therefore refers to the 0 job parameter block, and Bit 15 refers
to the 15th job parameter block in the specified data area.
A bit which is set in P3 denotes the start of the job specified in the asso-
ciated job parameter block.
If several bits are set at the same time, the associated jobs are transfer-
red to the R500 in the same cycle.
When the program cycle has run once on the R5REQ with the set job
bits, the job has completely started. The job bits must then again be reset
via the respective application program.
