4 Slave Configuration
This chapter describes how to create an EtherCAT slave configuration using TwinCAT and the
EL9800 Evaluation board.
4.1 Digital I/O Slave
The ET1100 and ET1200 provide the possibility to handle up to 32 (ET1100) digital signals without a
connected local uController (and slave software). These are called simple devices. This chapter
describes how to configure such an EtherCAT slave.
NOTE: Only the piggyback board FB1111-0142 shall be used in this configuration.
a. Power off the EL9800 Evaluation board
b. Set PDI selector to position 0
c. Power on the EL9800 Evaluation board
d. Start the TwinCAT System Manager
e. Scan the network (chapter 3.3.1)
f. Write the Device Description for 16 Bit Digital I/O to the EEPROM (Figure 18: 16Bit Digital I/O
Device Description).
How to write the EEPROM is described in chapter 3.3.2).

g. After writing and verification was successful close the “Advanced Settings” Dialog
h. Power off the EL9800 evaluation board
i. Set PDI selector to position 4
j. Power on the EL9800 evaluation board
k. Rescan for EtherCAT slaves (right mouse click on “Device xx (EtherCAT)”-> “Scan Boxes”
l. If a “Configuration changed” dialog is shown click “Copy all” and acknowledge this dialog with
“OK”.
m. Activate “Free Run” (“Free Run” can also be activated by pressing Ctrl+F5)
