Specify the block number of the extension file registers.
• If 0 is specified for the block number, monitor registration
is performed for the file registers of the PLC CPU.
(The same processing as monitor registration of R
the processing code for monitor registration of device
memory will be performed.)
• If a number greater than 0 is specified for the block number,
monitor registration is performed for the extension file registers.
• The maximum value that can be specified for the block
number varies depending on the PLC CPU's memory.
Specify the device number of the extension file registers (R).
The maximum value that can be specified for the device
number is the value set in the parameters of the PLC CPU.
