7.3.2 Communication Port Number Table
The GOT-F900 Series is equipped with built-in serial interfaces as shown below.
7.3.3 Connection Concept in Each Model Name
1) F940WGOT
When the RS-422 (COM0) port is used to connect the PLC, connect the next GOT-F900 to the RS-
232C (either COM1 or COM2) port. When the RS-232C (COM1) port is used to connect the PLC,
connect the next GOT-F900 to the RS-422 (COM0) or RS-232C (COM2) port.
2) F930GOT/F930GOT-K/F940GOT
When the RS-422 (COM0) port is used to connect the PLC, connect the next GOT-F900 to the RS-
232C (COM1) port.
When the RS-232C (COM1) port is used to connect the PLC, connect the next GOT-F900 to the RS-
422 (COM0).
3) Handy GOT
Only one Handy GOT unit can be connected at the end of two or more GOT units. After the Handy
GOT, no GOT-F900 can be connected.
*1 The RS-232C port for the Handy type GOT is provided inside the rear cover. As a result, environmental
protection is lost when using this port and such a connection is not practical. (The Handy GOT can be
connected as the final unit in a string of two or more GOTs.)
