Description
Enter timeout in ms (default = 250 ms).
Note: For Modbus field ports, the default timeout of 250
ms might not be sufficient in case of lower baud rates
(1200, 2400 etc.,) and needs to be increased.
Calculate the field port timeout as Field port timeout =
(1000 / baud rate) * No of bits in a byte * Maximum
number of bytes retrieved from Modbus device in a
single request ms and configure it accordingly.
Select 1 or 2 (default = 1).
