"Input data" area
Note:
The following two settings can be simultaneously acti-
vated.
They determine the frequency of data transmission.
Activating the COS update
Determines that the SP-COP2-ENI module immediately
updates the data in the PLC as soon as changes are made
to the data sets.
Activating the heart beat inter-
val
Use the heartbeat intervals which you defined in the
He-
artbeat interval
column to activate the update of the
selected data sets.
Table 22: Settings for network -> samosPRO COMPACT direction
"Output data" area
Selection list Determines the transmission method.
Value: Gateway reads from register
Column
Set
Determines which data are to be written to the PLC or
read from it.
Mark the control boxes for the desired data sets for this
purpose.
You will find a detailed description of the data sets here:
Data transferred to the network (network input data sets)
[ch. 3.2, p. 18]
Column
register address
Define from and to where in the PLC memory the selec-
ted data should be read and written.
Column heartbeat interval
Defines how often the data sets are to be updated.
Table 23: Settings in Area 3
Area 3
PLC IP address
Control ID
The parameters define from and to where the data in the
Modbus-TCP network are to be read and written:
Maximum refresh time for PLC
Define the maximum rate (or the minimum time interval)
for transmitting the data sets to the PLC. This setting
depends on the processing speed of the PLC. Minimum =
10 ms, maximum = 65535 ms. The basic setting of 40 ms
is suitable for most PLC
Note: When these values are greater than the heartbeat
interval, the
heartbeat interval
will be slowed down to
this value.
 Combine samosPLAN5+ with the samosPRO system and transmit the configuration.
