800 standard expanding
You can expand an easy800 standard using the easyLink network:
•
Locally with expansion units EASY618-..-RE, EASY620-DC-TE,
EASY410-DC-.E, EASY406-DC-ME, EASY411-DC-ME, EASY202-RE.
•
Remotely via the non-safety coupling module EASY200-EASY and one of
the above mentioned easy600 expansions connected to it.
You can also use communication expansion units such as:
•
EASY204-DP for PROFIBUS-DP.
•
EASY221-CO for CANopen-Bus.
•
EASY205-ASI for the Actuator-Sensor-Interface bus.
•
EASY209-SE for Ethernet.
•
EASY222-DN for DeviceNet.
Install the units and connect the inputs and outputs as described
(
Section 2.2, “Mounting the expansion unit“, Page 22).
The inputs of the expansion units are processed in the circuit diagram of an
easy800 device as contacts like the inputs of the basic device. The input
contacts are assigned the operand identifiers R1 to R12.
R15 and R16 are the group fault alarms of the expansion devices with
transistor outputs (
section 9.8, “Displaying device information”, page
The outputs of the expansion units are processed as relay coils or contacts
like the outputs in the basic device. The output relays are S1 to S8.
How is an expansion unit detected?
If at least one
R
contact or contact/coil
S
is used in the circuit diagram, the
basic device assumes that an expansion unit is connected.
Link transfer behavior
The input and output data of the expansion units is transferred via easyLink
serially in both directions.
Take into account the longer response times of the inputs and outputs of
expansion units compared to those of the basic device.
Response times of the inputs/outputs of the expansion units
The debounce setting has no effect on the expansion unit.
Transfer times for input and output signals:
•
Central expansion
•
Time for inputs R1 to R12: 30 ms + 1 cycle.
•
Time for outputs S1 to S6 (S8): 15 ms + 1 cycle.
￫
The EASY618-..-RE provides the outputs S1 to S6. The other
outputs S7, S8 can be used internally.
