12.3.4. Fixed data length (byte 5, byte 6)
These two bytes determine the length of the response data string. The converter
waits until the data arriving at the COM port buffer has reached the specified length.
To use this feature, the "Input fixed length data" parameter has to be set to
"Enable".
12.3.5. Interval time (byte 7)
This byte can increase the interval time between two batches of the data packet. It
means the converter can delay the data output from PROFINET to the COM port.
Example:
Interval time – 15 ms.
12.3.6. Timeout value (byte 8)
The timeout is only relevant for the communication between the I-7580 converter
and the serial network. The converter receives the response of the device at the COM port
as a continuous data stream. A silent interval in the data stream exceeding the timeout
value signals the converter the end of the message and forwards this message to its
PROFINET IO device output buffer.
Valid values for the timeout: 0 to 255.
The value "0" represents the minimum value which equals the transmission time of
one byte [(start bit+data bit+parity bit+stop bit)/Baudrate].
The value "1" assigns a timeout value of either 1 or 10 milliseconds depending on
the chosen unit (1 or 10 ms).
The value "255" represents either 255 milliseconds (time unit: 1 ms) or 2550
milliseconds (time unit:10 ms).
