SmartWire-DT Gateway EU5C-SWD-EIP-MODTCP 08/17 MN120003Z EN www.eaton.com 89
The diagnostic bits of the individual SWD modules can be looked up in the
"SmartWire-DT Modules IP20", MN05006001Z.
Example for output data:
The M22-SWD-K11-LED-R function element has a red LED for illuminated
pushbuttons and the two switch states 0 and 1. With cyclical output data of
one byte, it contains information on switch position and diagnostic informa-
tion.
Byte 0:
Extended diagnostic services
If a SWD module is signaling "Diagnose," i.e., if bit 4 of input byte 0 is set to
1, the corresponding details can be obtained by evaluating the extended diag-
nostic services.
