The DP data area is: maximum:
240 bytes in DP master mode
86 bytes in DP slave mode
In cyclic DP mode, the job
confirmation on the program block
interface includes the confirmation
of the transfer to PROFIBUS.
Application and functions
1.6 Compatibility with the previous product
New response of the device types
CP 342-5 6GK7 342-5DA02-0XE0
CP 342-5 6GK7 342-5DA03-0XE0
The following applies to the DP master mode:
With the version of the CP 342-5 described
here, the following services of program block
DP_CTRL are no longer supported:
CTYPE = 1
These job types are rejected with code 8311
The following applies to the DP master mode:
With the version of the CP 342-5 described
here, the following services of program block
DP_CTRL are no longer supported:
CTYPE = 0 command mode = CLEAR
These job types are rejected with code 8318
The following applies to the DP master mode:
With the version of the CP 342-5 described
here, the following services of program block
DP_CTRL are no longer supported:
CTYPE = 0 group select = 0
These job types are rejected with code 8318
The DP data area is: maximum:
2160 bytes in DP master mode
240 bytes in DP slave mode
Depending on the configuration, the older
program block types can also be used along
with the new program block versions. Note
the version identifiers for the block library of
STEP 7.
For the CP described here, the information in
the current description of the program blocks
applies.
Refer to /4/ (Page 54).
In cyclic DP mode, the processing cycle on the
CPU is separate from the processing cycle on
the CP.
Send data: The confirmation of the job
includes no confirmation of the successful
transfer to PROFIBUS.
Receive data: It is possible that the same
data was received several times.
