Fault Protection
Keep latest data
Clear all data bits to 0
Set to user defined value
If the MGate’s connection to the other side
(server/slave) fails, the gateway cannot receive
data, but the gateway will continuously send
output data to the Modbus TCP server device.
To avoid problems in this case, the MGate can
be configured to react in one of the following
three ways: Keep the latest data, clear data to
zero, set the data bits to user-defined values.
User-defined
Value
(This will
show up when
you select Fault
Protection mode
as 'Set to user
defined value'.)
00 to FF (Hex)
00 00
The user-defined values to write into the data
bits when the Set to user defined value option
is selected.
Fault Timeout
(This will show up
when you select
Fault Protection
mode as 'Set to
user defined
value'.)
1 to 86400 ms
3600
Defines the communication timeout for the
opposite side.
Tag Type
raw, boolean, int16, int32,
int64, uint16, uint32,
uint64, float, double, string
raw
Specifying the tag data type. The default is raw
for fast multiple data mapping.
For other data types, you could also scale the
resource data. There are two types:
•
Slope-intercept:
tag value = (source value * slope) +offset
•
Point-slope:
tag value = source value *
( )
target max. - target min.
source max. - source min.
