Preface
The ET 200U distributed I/O station belongs to the ET 200 distributed I/O
system with the SINEC L2–DP field bus.
The distributed I/O station operates with the DP Siemens, DP Standard and
FMS protocols.
The DP Siemens bus protocol has been developed by Siemens especially for
the ET 200 distributed I/O system.
The DP standard bus protocol, a further development of DP Siemens, com-
plies with the PROFIBUS–DP draft standard (DIN 19245, Part 3), the
PROFIBUS solution for high–speed field applications.
FMS is the PROFIBUS bus protocol described in DIN 19245, Part 2.
