bit 2: "Default"
After "1" is written in, all the setting items are set to the initial conditions (Transmission
mode: A mode, I/O control numbers: 512) by reset (HML0 + 4D), and the address informa-
tion of the recognized units is cleared. If "1" is written into HML0 + 49 bit 2, HML0 + 4A bit 2
turns to "1" after the completion of the default setting. Then, execute the reset (HML0 + 4D).
bit 3: "System set"
It reads in the S-LINK V I/O unit connection state at that time. If "1" is written into HML0 +
49 bit 3, HML0 + 4A bit 3 turns to "1" after the completion of system setting.
bit 4: "Interruption indication"
In case interruption has occurred, HML0 + 4A bit 4 turns to "1." In order to clear this, write
"1" into HML0 + 49 bit 4 to execute, and the clearance is completed when HML0 + 4A bit 4
turns to "0." In case "0" is written into HML0 + 49 bit 4, it is ignored. After the clearance, in case
HML0 + 49 bit 4 does not return to "0," it will be cleared soon after the next interruption occurs.
bit 5: "Busy indication"
When the Busy indicator lights up, such as during system setting, "1" is indicated in HML0 +
4A bit 5. After the Busy state is over, it turns to "0."
Even if written into HML0 + 49 bit 5, this will be ignored.
bit 6: "On Hold indication"
In case the input hold is effective (HML0 + 4E bit 0 is "1"), the current state is indicated with
Hold "1" or the state before Hold with "0." When Hold cancel (HML0 + 4E bit 0 is "0") is set,
it returns to "0."
bit 7: "Command under execution indication"
After the receipt of each command of HML0 + 49 bit 0 to 4, HML0 + 4A bit 7 turns to "1" until
the command completion. When the command execution is completed, it turns to "0." This
bit allows you to check if a command has been received.
Notes: 1) Once each command of bit 0 to 4 is executed, the bit value does not return to the original value.
In order to execute the next command, write "0" into the bit corresponding to HML0 + 49 once and
check that the bit corresponding to HML0 + 4A has turns to "0" prior to the execution.

Command
2) "System set" and "Command" cannot be executed during an interruption occurrence. Only
clearance of the interruption can be carried out.
8) HML0 + 4B: Bank change-over request register
9) HML0 + 4C: Bank change-over response register (read out only)
These are used when changing the bank of "1) HML0 + 00 to HML0 + 3F: Data area."
First, write a value ("00H to 07H") in "8) HML0 + 4B: Bank change-over request register"
through the computer.
After 1 to 2 refresh times, the control board changes over the bank of, "1) HML0 + 00 to HML0 +
3F: Data area" and writes the changed bank number in "9) HML0 + 4C: Bank change-over re-
sponse register."
Notes: 1) In case a number other than "00H" to "07H" is written in "8) HML0 + 4B: Bank change-over
request register," it compulsorily changes bank as "00H."
2) Do not read out / write in "1) HML0 + 00 to HML0 + 3F: Data area" until "9) HML0 + 4C: Bank
change-over response register" has been changed over.
10) HML0 + 4D: Transmission stop / Reset
● In order to stop the transmission of S-LINK V system, write "0FH" into HML0 + 4D. In order to
restart it, write in the reset command.
● This resets the S-LINK V system. (In case I/O setting has been changed at "4) I/O setting
switch (SW3, SW4)" in "3. Functional Description," the change is reflected.)
If "1EH" is written in HML0 + 4D, I/O data is cleared and then reset. In case "2DH" is written, I/O
data is held and then reset. In case a value other than these is written, it is ignored.
● Even if the transmission mode or I/O control number is changed, the setting is not changed with
this reset command.

Execution
The order of priority for each command of bit 0 to 3 is
bit 0 > 1 > 3 > 2.
