*1: 38400 bps can be specified when the UT75A/UT55A/UT35A/UP55A/UP35A suffix code Type
3 = 1 or UT52A/UT32A/UT32A-D/UP32A/UM33A suffix code Type 2 = 1.
*2: This parameter may not be displayed depending on the parameter display level (LEVL) setting.
*3: UT75A/UT55A/UT52A/UT35A/UT32A/UT32A-D/UP55A/UP35A/UP32A only.
*4: UT75A/UT55A/UT52A/UT35A/UT32A/UT32A-D only.
*5: UT75A/UP55A only.

Description
● Protocol selection
Select the protocol to be used.
● Baud rate
Set the same baud rate as the host computer that the controller is to be connected to.
The baud rate unit is bps (bits per second).
● Parity
Set the same parity bit as the host computer that the controller is to be connected to.
Set the handling of parity to be carried out when data is sent or received.
● Stop bit
Set the same stop bit as the host computer that the controller is to be connected to.
● Data length
Set the same data length as the host computer that the controller is to be connected
to.
Modbus communication (ASCII): Fixed at 7 bits.
Modbus communication (RTU) and ladder communication: Fixed at 8 bits.
● Address
Any number within the range 1 to 99 can be set. (Numbers need not be consecutive
and can be skipped. However, set only unique numbers within the same system.
Do not set the same address twice.) The maximum connecting configuration is 31
controllers.
● Minimum response time
Set the time from when receiving a communication command to responding to it. The
minimum response time unit is 10 ms. The actual response time is calculated using
the equation: Communication processing time + setting value of PR.T x 10 (ms).
