Description
Here the delay time may be preset in ms.
The Character Delay Time is the time that may elapse
between two characters within a Modbus frame.
The receiving station checks the incoming data for time out
and if detected the message is ignored and an error is indi-
cated.
Range of values: 1 ... 6500ms
n
Here a waiting time in ms may be preset spent by the CP
waiting for a reply message from the slave after output of a
request message.

Here the operating mode of the driver may be set.
In Normal Operation every recognized transmission error
and break will result in error handling, even if the driver is
in idle mode.
In the operating mode Interference suppression transmis-
sion errors and breaks are ignored when the driver is in
idle mode. If the driver leaves the idle mode transmission
error and break will result in error handling.
Range of values: Normal operation, Interference suppres-
sion
The register oriented function codes 03, 06, 16 can also
handle 32bit registers.
By setting of this parameter the driver is prepared to
handle registers with the length of 4 Byte.
The decision whether 16bit or 32bit is done via the byte
which contains the function code.
By setting of the 6. bit in the function code a 32bit register
is accessed.
If the 6. bit is not set a 16bit register is accessed.
