Expanding easy800 You can expand easy800 with easy models EASY618-..-RE ,
EASY620-D.-TE, EASY202-RE locally or use the
EASY200-EASY coupling module for remote expansion with
easy600 expansion. All available bus interface devices such
as EASY204-DP, EASY221-CN, EASY205-ASI or EASY222-
DN can be used if present.
Install the units and connect the inputs and outputs as
described (see a Section “Connecting the expansion
device”Page 34).
You process the inputs of the expansion devices as contacts
in the easy circuit diagram in the same way as you process
the inputs of the basic unit. The input contacts are assigned
the operand designations R1 to R12.
R15 and R16 are the group fault inputs of the transistor
expansion unit (a Section “Monitoring of short-circuit/
overload with EASY..-D.-T..”, Page 297).
The outputs are processed as relay coils or contacts like the
outputs in the basic unit. The output relays are S1 to S8.
How is an expansion unit recognised?
If at least one
R.. contact or S.. coil/contact is used
in the circuit diagram, the basic unit assumes that an
expansion device is connected.
h
EASY618-..-RE provides the outputs S1 to S6. The other
outputs S7, S8 can be used internally.
