6.4.0.3 Example 3: Automatic reset of error signal
The circuit diagram functions in the same way as Example 2. In addition the
marker M16 is reset every 60 seconds by timing relay T8 (on-delayed, 60 s).
Should I16 remain at 1, M16 will continue to be set. Q1 is set briefly to 1 until
I16 switches off again.

700 expanding
You can expand easy700 with EASY410-DC-.E, EASY618-..-RE, EASY202-RE
or EASY620-D.-TE modules locally or use the EASY200-EASY coupling
module for remote expansion.
For this first install the units and connect the inputs and outputs
(
Chapter 2 "Installation“, page 25).
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 identifiers R1 to R12.
R15 and R16 are the group fault alarms of the transistor expansion unit
(
Section "6.4 Monitoring of short-circuit/overload with EASY..-D.-T..“,
The outputs are processed as relay coils or contacts in the same way as
outputs in the basic unit. The output relays are called S1 to S8.
The following bus modules can also be connected:
•
EASY205-ASI (AS-Interface),
•
EASY204-DP (Profibus DP),
•
EASY221-CO (CAN open) or
•
EASY222-DN (Device NET).
These modules offer considerably more functions than simple I/O expansion
modules. Depending on type, all the data of the program can be read and
setpoints can be written. The functions of the individual devices are
described in the relevant documentation.
6.5.1 How is an expansion unit recognized?
easy checks cyclically whether a device is sending data via the easyLink

EASY410-DC-.E provides the outputs S1 to S4. The other outputs
S5 - S8 can be used as markers. EASY618-..-RE provides the
outputs S1 to S6. The other outputs S7, S8 can be used as
markers.
