5 Slave Addressing
Slaves for expanding
remote inputs/outputs The PS4-200 master PLC and the slaves for
expanding the remote inputs/outputs can
communicate with one another using the Sucone tK
or K1 protocols. The protocol is selected by the
master automatically according to the capabilities of
the slaves. It is not necessary to parameterize the
send or receive data length in the Topology
Configurator. Suconet K/K1 selects the appropriate
telegram length and automatically addresses the
relevant data ranges in your application.
You can thus access remote input/output operands
just as easily as local operands.

The RD/SD syntax must be used for certain types
of slave for expanding the inputs/outputs instead
of the I/Q syntax described here. Please refer to
the table in the Appendix for the correct
addressing for each station type.
