It is used for checking if the output data is sent to S-LINK V output unit.
In case data is sent to the same address at an interval shorter than the S-LINK V system
response delay time, the data may not be transmitted. After the output data is written, if "1"
is written into HL00 + 004C or HL00 + 014C bit 0, and the next output data is written in after

mission error can be avoided.
bit 1: "Error No. clear"
It clears the error No. in case the cause of error has been eliminated at "5) HL00 + 004A to
B HL00 + 014A to B: Error No. / Error state" in "5. Assignment on Program" and when
HL00 + 004A or HL00 + 014A bit 7 is "0." If "1" is written into HL00 + 004C or HL00 + 014C
bit 1, HL00 + 004E or HL00 + 014E bit 1 turns to "1" after the error No. is cleared.
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 (HL00 + 0054 to 5 or HL00 + 0154 to 5),
and the address information of the recognized units is cleared. If "1" is written into HL00 +
004C or HL00 + 014C bit 2, HL00 + 004E or HL00 + 014E bit 2 turns to "1" after the comple-
tion of the default setting. Then, execute the reset (HL00 + 0054 to 5 or HL00 + 0154 to 5).
bit 3: "System set"
It reads in the S-LINK V I/O unit connection state at that time. If "1" is written into HL00 +
004C or HL00 + 014C bit 3, HL00 + 004E or HL00 + 014E bit 3 turns to "1" after the comple-
tion of system setting.
bit 4: "Interruption indication"
In case interruption has occurred, HL00 + 004E or HL00 + 014E bit 4 turns to "1." In order
to clear this, write "1" into HL00 + 004C or HL00 + 014C bit 4 to execute, and the clearance
is completed when HL00 + 004E or HL00 + 014E bit 4 turns to "0." In case "0" is written into
HL00 + 004C or HL00 + 014C bit 4, it is ignored. After the clearance, in case HL00 + 004C
or HL00 + 014C 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 HL00 +
004E or HL00 + 014E bit 5. After the Busy state is over, it turns to "0."
Even if written into HL00 + 004C or HL00 + 014C bit 5, this will be ignored.
bit 6: "On Hold indication"
In case the input hold is effective (HL00 + 0056 or HL00 + 0156 bit 0 is "1"), the current
state is indicated with Hold "1" or the state before Hold with "0." When Hold cancel (HL00 +
0056 or HL00 + 0156 bit 0 is "0") is set, it returns to "0."
bit 7: "Command under execution indication"
After the receipt of each command of HL00 + 004C or HL00 + 014C bit 0 to 4, HL00 +
004E or HL00 + 014E 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.
