5.1 What is Two-way 2 Mode

5.1.1 Overview of Communication Mode

In the two-way 2 mode, an external device sends a command to the GT, and the GT sends a message
for transmitting the information on the switch input/data settings. In this mode, the GT sends back a
response for a command to the external device.
The readout commands in the word device area and the bit device area (with responses) can be used.
Key Point: In the two-way 2 mode that the response function is available, the external device can
detect errors because no response is returned.
[Using two-way 2 mode on GT01/GT02L]
• The external device should support full-duplex transmission to use the two-way 2 mode on the
GT01/GT02L.
