PLC
3) PLC numbers when appointing device
PLC numbers from 1 to 4 are allocated (smaller number for the unit closer to the power card).
Specify the target PLC number and device number when creating screen data.
When using QCPU with GOT-F900 connected, number 0 (own station) can also be specified.
Example:
Specify 1 to monitor the unit with PLC number 1.
Specify 0 or 3 to monitor the unit with PLC number 3.
11.4.2 Connection to serial communication
The required setting and PLC numbers for connecting the GOT-F900 to the serial communication unit
attached to the Q multiple PLC system are shown below. Note that there are restrictions on use of the
serial communication unit not compatible with the multiple PLC system. See below for its setting.
1) GOT-F900 connection
GOT-F900 can be connected to RS-232C or RS-422 port on the serial communication unit.
Connection of two or more GOT units can be performed and 2-port interface function (Program
transfer and monitor using GX Developer) is available.
2) Serial communication unit compatible with the Q multiple PLC system (Version B or later)
a) Setting in the screen creation software
GT Designer
Select MELSEC-Q (Multi) in the "GOT/PLC Type" dialog box.
Specify RS-422 or RS-232C for Port, CPU for Type, and 0 for Station No. in the "Project Auxiliary
Setting" dialog box.
DU/WIN
The setting is not available.
b) PLC numbers when appointing device
When the PLC No. is set to "0", the control CPU (No.2 in the example shown below) can be
monitored.
If one of the PLC numbers 1 through 4 is specified, the unit with the corresponding PLC number
can be monitored.
3) Serial communication unit not compatible with the Q multiple PLC system (Earlier than
Version B)
Version B or later is required for connecting the GOT-F900 to the serial communication unit attached
to the Q multiple PLC system (Version B).
4) Control PLC
Control PLC is the unit with the number specified under "PLC Parameter" - "I/O assignment" in the
GX Developer.
(No setting is available in the version of GX Developer not compatible with multiple PLC system.)
PLC number of CPU
1 2 3 4
Serial communication unit (Function version -B or later)
1 2 3 4
Set as control PLC (for example)
Each CPU can be monitored by
specifying PLC number 0 to 4.
