[Ethercat Device]
Description
Read 32-bit value from the specified object for such EtherCAT slave device.
Syntax
uint32_t sdoUpload32(uint16_t od_index, uint8_t od_subindex, uint32_t timeout_us = 100000);
Parameters
[in] uint16_t od_index
Index of the object.[in] uint8_t od_subindex
Subindex of the object.[in] uint32_t timeout_us
Timeout in microseconds.
Return Value
Return the 32-bit value.
Comment
This function must be called after a successful execution of EthercatMaster::begin()
. This function is blocking and cannot be called within the Cyclic Callback.
Example
#include "Ethercat.h" EthercatMaster master; EthercatDevice_Generic slave; void setup() { Serial.begin(115200); master.begin(); slave.attach(0, master); master.start(1000000); } void loop() { Serial.print("Value: "); Serial.println(slave.sdoUpload32(0x607A, 0x00)); delay(1000); }
