PROFIBUS DP Communication
‑161‑
PZDx(master‑>slave) indicates the address used by the master to write to the slave,
and PZDx(slave‑>master) indicates the address used by the master to read the
slave. PZD3 to PZD12 are displayed in decimal and can be modified. For example,
to set PZD3(master->slaver) to F0‑12, enter 61452.
By default, all PZDs of MD380 are set to F0‑00 (61440 in decimal). For unused PZDs,
modification is not required and default values can be retained. PZD mapping must
be set independently for each slave as required (if the mappings of various slaves
are the same, you can select a configured slave, press Ctrl+C, select the PROFINET
bus in the configuration, press Ctrl+V, and modify the device name and IP
address).
To enable the aperiodic parameter read and write function of DPV1, set
corresponding parameters in customized indexes at the end of Device-specific
parameters list. MD380 provides six customized indexes numbered from 0 to 5, as
shown in the following figure. For example, you can set index 0 to F0‑02 and index 1
to F0‑08.
