PLC cycle time
With regard to PLC cycle time on the ZE200-DP and ZE200A-DP, the follo-
wing shall be observed:
D For each 256 bytes of decentrally assigned I/O, the I/O state shifts by ap-
prox. 1 ms.
D In the case of diagnostic data processing or transmission problems on
the DP bus, a max. 30 % extension of the cycle time may be expected.
Baud rates
The transmission speed is set with the use of the WinDP configuration soft-
ware for the PROFIBUS and then stored in the master parameter set.
Configuration
The configuration of the DP section requires the use of the WinSPS / WinDP
software for Microsoft Windows.
Standard function modules
The following function modules are provided for the operation of the DP sec-
tion:
DP2STAT Operation of DP section with diagnostic transfer.
(If diagnostic functions are not required, decentrali-
zed operation can be carried out without this func-
tion module.)
FIFODM1 Required to handle FIFO modules in decentralized
application.
SPSKANAL Required for communication of all module types via
the channels.
Connecting cable
When operating a PROFIBUS field bus installation, both stations represen-
ting the bus termination must be powered up (active bus termination).
The following components are available for wiring the PROFIBUS:
Designation Order no.
