This function allows you to read the data acquired from an AXL_F_PM_EF_1F device and save it in a stru_pm_pd type ti structure or an i32 array.
The process information is read if the module is connected directly to the control or if it is connected to the EtherCAT head and then defined as device ECAT_PM.
NOTE: This instruction can be used only if the keyword ECAT_PM is included in rte.cfg.
