BLOC
: Bit location on the data memory
The register (file register) is to be designated using DSEG and DADR.
[Example] Register 09000
030000 of the file 1 : DSEG = 01
The relay address is to be designated using DSEG, DADR, and BLOC.
The destination is made by the combination of the file address and the bit location.
[Example] Relay 07252: DSEG = 00
TADR
: Timer/counter number
To assign a timer/counter number, use TADR. (Hexadecimal notation)
TADR
SADR
: System memory address
To assign a system memory address, use SADR. (Hexadecimal notation)
SEG should be assigned in the command. Always specify 08

Each command will be executed or depending on the current status of the write enable mode.
Write enable mode
Mode 0

Mode 2
When the power is first applied, the module is in "mode 0." Therefore, if you want to write data
from the host computer, change to "mode 1 or "mode 2" using the setting command (command
code F9
). The current status can be read using the reading command (command code E9
