Modbus/TCP Ethernet Gateway
Decide which of the following 6 data sets are to be transferred to the PLC. For the exact
description of the data sets please refer to section 7.8.
Data set
Description
1
Module-specific input data
2
Module-specific output data
3
Module-specific data of the UE410-EN3 gateway
4
General status and configuration data
5
Diagnostics data
6
Configuration data of the Flexi Classic system, user defined compilation
Select the desired data sets.
After the data sets have been selected, configure how they should be sent to the PLC.
For this purpose certain parameters that depend on the operating mode have to be set.
These are described below.

Description
See
section
Rx (To PLC)
Transfer Mode
Slave (PLC
Polls)
Determines the type of data transfer from UE410-
EN3 to the PLC.
Slave (PLC Polls)
— PLC requests the data.
Master (Write to PLC)
— UE410-EN3 writes the
data to the PLC memory.
Tx (From PLC)
Transfer Mode
Slave (PLC
Writes)
Determines the type of data transfer from the PLC
to UE410-EN3.
Slave (PLC Writes)
— PLC writes to the UE410-EN3
memory.
Master (Poll the PLC)
— UE410-EN3 requests data
continuously from the PLC.
Settings for the operating modes Master RX and/or Master Tx
PLC IP Address
0.0.0.0
Specifies the PLC address in standard format xxx.xxx.xxx.xxx.
The selected data sets are transferred here.
PLC Device ID
1
Specifies the PLC device ID (typically 1).
Settings for the operating mode Master (Write to PLC):
Maximum PLC
Update Rate
40
Defines the maximum rate (the minimum time interval) for
sending the data sets to the PLC. Settings occur dependent on
the PLC processing speed.
Minimum = 10 msec. Maximum = 65535 msec. The default
value of 40 msec. is suitable for most PLCs.
Note: If this value is greater than the Heartbeat Update Interval,
the Heartbeat Update Interval is increased (slowed down) to
this value.
Enable Heartbeat
Message
Deactivated
Activates updating of the active data sets with the set Heart-
beat Update Rate.
Note: Either this option or Update Immediately on Status/Confi-
guration Change must be activated, otherwise no data will be
transferred!
