3.3 Detals on Functons
Tme Out Operaton
When reading tag data, after sending a register value request message to the Modbus
device, if the message is not received within the specified time out time that tag is
considered to have timed out. If Use Retry is set to ON, for tags on which a timeout
occurred, retries are attempted starting from the next acquisition interval at the specified
retry interval until communication is restored.
If Retry is turned OFF, a retry is not performed on the tag on which a timeout occurred,
and data reading is not performed for that tag thereafter.
To reopen communications after loading stops, choose the target device for
communication in the Acquisition/Status tab, then click the Reconnect button.
Note
Using GateCONTROL, data can be acquired concurrently on each COM port. Therefore data is
logged more efficiently when connecting each device to a separate port rather than connecting
several devices to a single port.
