Suconet K interface
The RS 485 interface is galvanically isolated from the
CPU. It has the following functions:
Networking of Suconet K stations (e.g. EM4...
expansion modules)
Data exchange with partner devices that have a
serial port (printers, terminals, etc.). This
communication interface is used for process data
acquisition, visualization, etc. Data for process
control must not be exchanged here.
Programming networks for several PLCs via a PC
(see section “Programming with Suconet K” in
the “Operation” chapter).
Setpoint potentiometers
You can set the two setpoint potentiometers P1 and
P2 externally, in other words direct adjustment
without the need for a programming device. The
resolution is 10 bits (1024 increments). They can be
accessed with the operands “IAW0” and “IAW2”.
Switch S1 for bus terminating resistors
You can set the bus terminating resistors for the first
and last physical stations with switch S1.
