Keep connection
Set this to On to maintain the connection with the external device.
Connection timeout
If you set Keep connection to On, set the duration to maintain the TCP connection with the
external Modbus device.
Explanation
Keep connection
Set whether to connect and disconnect TCP connections every time the GX/GP accesses an
external device.
If you set Keep connection to On, the TCP connection/disconnection procedure is skipped,
thereby reducing the amount of communication traffic between the devices.
However, some devices do not support this feature. Use this feature after you check the
specifications of the connected devices.
Even if Keep connection is set to OFF, if the communication interval is less than 1 s,
communication is performed as if Keep connection set to ON.
