Goodrive350 series VFD Auto Station programmable expansion card Auto Station programming interfaces
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 Auto
Station interface variables C_WrRece_PZD1–C_WrRece_PZD12). Then the PLC card sends
this group of D elements to the DP/CANopen/PN card parsing program on the DSP for
parsing.
As shown in the figure, the host computer receives data by using the reading channels.
① The DSP sends data to the PLC card by using D7436–D7447 (corresponding to Auto
Station interface variables I_RdSend_PZD1–I_RdSend_PZD12).
② You can use the Auto Station to perform secondary programming on D7436–D7447
(corresponding to Auto Station interface variables I_RdSend_PZD1–I_RdSend_PZD12). After
the processing, the data is sent to D7648–D7659 (corresponding to Auto Station interface
variables C_RdRece_PZD1–C_RdRece_PZD12). Then the PLC card sends this group of D
elements to the DSP channels for communication with the DP/CANopen/PN card.
③ After receiving the data, the DP/CANopen/PN card sends the data to the host computer.
