returned from the slave containing the Prm_Req flag. This flag indicates that
the Master Unit should re-parameterize the slave, but in the case of reduced
performance slave devices, the returned flag also indicates that the slave
device is still processing the last received parameter message and has as yet
not approved nor rejected that message.
During the Diagnostics Update Delay period the PROFIBUS Master Unit will
continue requesting its diagnostics data. Also during this period, the diagnos-
tics data received from this slave will not be updated in the PLC CPU.
PROFIBUS DP-V1 defines extended communication functions between a
PROFIBUS DP-V1 master and a PROFIBUS DP-V1 slave device. These
extensions include:
• Acyclic communications between master and slave, to allow re-parame-
terization, during I/O data exchange.
• Extended alarm reporting and acknowledgement.
Settings related to these extensions are sent to the slave device through the
Set_Prm message.
1. The PROFIBUS DP-V1 settings in this tab refer to PROFIBUS DP-V1
Class 1 communication only. For PROFIBUS DP-V1 Class 2 communica-
tion no specific settings are required.
2. The CS1/CJ1W-PRM21 PROFIBUS DP Master units will automatically
disable the DP-V1 settings to avoid the slave devices to use PROFIBUS
DP-V1 functions. Only the CS1/CJ1W-PRM21 PROFIBUS DP-V1 Master
Units will use the settings below.
The DPV1 settings window is shown below.
This checkbox enables or disables the DPV1 functions for the specific slave
device. The Master DTM will clear this setting prior to download.
