5-13 Communications Setting Parameters

Level
Communications
Setting
Set the setting parameters related to RS-485 communications.
Use the Unit Number Setting Switch on the Main Unit front part to set the
unit number. The setting is applied after a power ON reset.
The Send Wait Time setting parameter is the wait time from when the K7GE-MG receives a command
from the host system until it returns a response. If the response comes so fast that the host system
cannot receive it properly, increase this setting value. If you want to make the communications
response time faster, decrease this setting value.
When the Modbus RTU protocol is selected, regardless of the setting value of the setting parameter, the data length is
fixed internally at 8 bits, and the stop bit is fixed internally at 1 bit when the parity is even/odd or fixed internally at 2 bits
when the parity is none. Use it with caution.
The operation procedure for the Baud Rate setting parameter is shown as follows:
Procedure
1.
Press the Level Key for at least 3 seconds in the Operation
Level to move to the Initial Setting Level.
•
The LVL/CH display will indicate 0, and the LVL indicator will light
to show that the Initial Setting Level has been entered.
2.
Press the Level Key at the Initial Setting Level (for less than 1
second) to move to the Communications Setting Level.
3.
Press the Mode Key several times to display bps.
