UD70
Issue code: 70nu2
Serial communications 6-15
Using Mode 11
When other modes are used, the start of data transmission and reception
can be delayed up to 8ms. When mode 11 is used, the data bypasses the
internal software FIFO, buffer which reduces the delays in the system.
Parameter #17.07 is used to program the baud rate.
Using modes 13 and 14
The Modbus protocol is only supported as a slave. Modes 13 and 14 do not
allow the UD70 to act as a Modbus Master. The baud rate is selected using
parameter #17.07.
