8.3 Cautions on Use of MELSEC-F FX Series
When using the GOT-F900 connected to the FX Series PLC, observe the following cautions on use.
8.3.1 Device specification
The device range specifications vary depending on the model of the FXCPU.
Input relays (X) X000 to X377 can be read only.
It is not allowed to specify a bit device as a word device or specify a word device as a bit device.
For the details, refer to section 3.3.
8.3.2 Devices which can be monitored
Specify the device No. of input relays (X) and output relays (Y) in octal (1, 2, 3 ... 7, 10, 11 ... 17, 20).
Specify the device No. of other devices in decimal.
Only devices described in "3.3 Device Names Which can be Monitored" can be specified.
8.3.3 When GOT-F900 is connected to optional port
By connecting the appropriate module to the FX Series PLC (see table below), the GOT-F900 can be
connected to the optional port.
In this case, set the GOT-F900 to CPU direct connection. No setting is required in the FX Series PLC
because programming communication is specified at the time of shipment from the factory.
These optional por ts enable communication using either communication protocol, no protocol
communication, computer link, easy PLC link, parallel link and programming.
For connecting the GOT-F900, the programming communication mode should be selected (which is set
at the time of shipment from the factory). If any other protocol or an improper protocol has been set,
release the setting (by a sequence program or the software) while referring to the procedure below.
1) To set by a sequence program
- Delete the no protocol communication (RS instruction).
- Delete programs set by computer link, easy PLC link and parallel link.
- Delete the setting of communication parameters (D8120). (If the parameters are set using the
software for sequence program, refer to the description on the setting by the software also.)
For the details on the program settings, refer to the "FX COMMUNICATION (RS-232C/RS-422)
USER'S MANUAL".
