6. Now you might see some errors in registers 0x030C-0x0313 resulting from power-up. These
errors have no significance, only errors increasing during operation are important.
TwinCAT reads out and clears only the error counters in register 0x0300-0x0307, and pressing the
button “Clear CRC” also clears only these counters. The other counters are still accumulating from
power-up until now.
Please note that the error counters are shown as 16 bit values
, i.e., the column called “Reg. 0300”
shows in fact registers 0x0300 (lower 8 bit, right side) and 0x0301 (higher 8 bit, left side).
Press the buttons “Clear CRC” and “Clear Frames” to clear the TwinCAT counters in the lower
right area (Lost frames, Tx/Rx Errors).
