About transmission delay
"Transmission delay" is a setting for low-speed devices that cannot respond quickly to transmission responses.
"Transmission delay" is initially set to 0 ms and it is necessary to set it with GT Designer3 (GOT2000) in order to change it.
For details on settings, refer to the following..
GOT2000 Series Connection Manual (Microcomputers, MODBUS/Fieldbus Products, Peripherals)
