When the GOT is connected to the MELSEC A Series PLC via a computer link unit, the follow-
ing setting is required.
• Setting of computer link unit
Set the communication format of the computer link unit as shown below.

The GOT does not control CD signals. Accordingly, when the RS-232C is connected, the
buffer memory in the computer link unit should be set so that CD signals are not checked.
Example: When I/O signals in the computer link unit are 80 (H) to 9F (H)

In connection via computer link unit, the following functions of the GOT are disabled.
- Index registers (V and Z) cannot be monitored, and their current values cannot be
