5.14 EtherCAT Slave Controller (ESC)
To run the EtherCAT slave controller software, the EtherCAT ID number is required. Please use SW3 as
necessary.
The CPU board has an EtherCAT slave controller (ESC) and is connected to the ESC module of the
microprocessor. EtherCAT status LEDs are listed in section 5.4. The EtherCAT connections to and from the
MPU are shown in Table 5-15, Table 5-16, Table 5-17, Table 5-18, Table 5-21 below.
Note that ESC port 2 cannot be used at the same time as SDRAM.
