*1 The GOT ensures in advance the minimum interval (3.5 characters time) for communication frame defined in the MODBUS/RTU.
Therefore, the actual send delay time is as follows.
When connecting to MODBUS/RTU master equipment which requires a delay longer than 3.5 character time, adjust the send
delay time.
POINT POINT POINT
If the communication with MODBUS/RTU master equipment is not established, some equipment
which requires a delay longer than 3.5 character time may be connected.
Adjust the send delay time in the communication detail setting.
