2.6 MELSEC-FX
The device ranges that can be set when selecting 
[MELSEC-FX] as the controller type are as follows.
*1
When executing the touch switch function set during the bit 
specification of the word device, do not write any data to the 
word device through the sequence program.
*2
The device No. must be set in multiples of 16.
*3
Only 16-bit (1-word) designation is allowed.
*4
For CS0 to CS199, only 16-bit (1-word) designation is 
allowed.
For CS200 to CS255, only 32-bit (2-word) designation is 
allowed.
*5
Monitoring or writing is not possible in the continuous device 
designation mode.
In addition, setting values of the timer and counter, which are 
not used for the program, cannot be monitored. If monitoring 
is executed, a reading error occurs.

This is not supported by GT10.

(1) Precautions when using the buffer memory
• When the power supply of the special block or 
special module is turned off, the contents of the 
buffer memory are initialized, except for some 
keeping areas.
• When the buffer memory is monitored by the 
GOT, the PLC scan time may increase instantly.
• Use the 16 bit specification for the buffer 
memory of 16 bit data. Use the 32 bit 
specification for the buffer memory of 32 bit data. 
If using the 16 bit specification for a buffer 
memory of 32 bit data, monitoring and writing 
may not be executed normally.
For the data size of each buffer memory, refer to 
the following.
User's Manual of the special block or special 
module
• When reading from/writing to the special block or 
special module by interrupt processing of the 
sequence program, monitoring/writing from GOT 
to the buffer memory may not be executed 
normally.
(2) How to select a keyword protection level
For equipment that are allowed to operate the FX 
PLC online, 3 levels of protection level can be set.
When monitoring or changing settings by any 
online equipment is required, set a keyword 
referring to the following.
(a) When setting the keyword only
Select a protection level by the initial letter of 
the keyword.
All operation protect: Set a keyword with the 
initial letter "A", "D" to "F", or "0" to "9".
Incorrect write/read protect: Set a keyword 
with the initial letter "B".
Incorrect write protect: Set a keyword with the 
initial letter "C".
(b) When setting the keyword and 2nd keyword
Select a protection level by [Registration 
condition].
(3) Monitoring availability at each keyword protection 
level
The following shows the device monitoring 
availability at each keyword protection level.
*1
When the T, C set values are specified indirectly, changing 
devices is available.
(4) Difference between all online operations 
prohibition and all operations prohibition
When specifying all online operations prohibition, 
displaying devices and inputting data with 
programming tools or GOT are all prohibited.
When all operations are prohibited, displaying 
devices and inputting data with the GOT are 
enabled while all operations using programming 
tools are prohibited.
