Field module with semiconductor relay for EEV for advanced functions
4 FKL003-A_V3.60_PI_2022-11_EN
Subject to technical changes
FKL003-A
CAN bus address setting
To register the FKL003-A correctly on the CAN bus, you have to assign a unique CAN bus address to it
with the coding switch. This is a requirement for functioning communication with the master module.
You can set CAN bus addresses 0...7 with the coding switch. You can thus connect 8 field modules
to the CAN bus.
