The following describes the communication channel between the PLC card and
DP/CANopen/PN card. The PLC card defines two groups of PZD channel, used for writing
and read, and each group has 24 PZD channels. The writing channels are used to send data
from the DP/CANopen/PN card to the PLC card for secondary programming and then send
the processed data to the VFD. The reading channels are used to send data from the VFD to
the PLC card for secondary programming and then send the processed data to the
DP/CANopen/PN card. The following figure shows how the data is transferred.
Figure 4-9 Data transfer between the PLC card and DP/CANopen/PN card
As shown in the figure, the host computer sends data by using the writing channels.
1. The host computer sends commands/data to the DP/CANopen/PN card.
2. After parsing the data from the host computer, the DP/CANopen/PN card encapsulates
the data into frames and sends the frames to PZD1–12 on the DSP. This group of PZD
are transferred to the corresponding elements D7424–D7435 (corresponding to Auto
Station interface variables I_WrSend_PZD1–I_WrSend_PZD12) on the PLC card.
3. You can use the Auto Station to perform secondary programming on D7424–D7435
(corresponding Auto Station interface variables I_WrSend_PZD1–I_WrSend_PZD12) on
the PLC card. After the processing, the data is sent to D7636–D7647 (corresponding to
