A.2.2 Communication Relays List (L
)
Special register for data link
HS link No. 1 ~ 12
No. Keyword Type Detail Description
L000000 _HS1_RLINK Bit
HS link parameter No.1’s
all stations normally
operated
Displays all stations normally operated as specified in HS link parameter, which will be On
if
1.There is no RUN mode error in all stations specified in parameter
2.All data block is in normal communication as specified in parameter.
3.The parameter specified in each station itself is in normal communication.
Run_link will be kept On if once On until stopped by link disenable.
L000001 _HS1_LTRBL Bit
After _HS1RLINK is ON,
abnormal status displayed
This flag will be On if the station specified in parameter and the data block’s
communication status are as described below with _HSmRLINK flag On,.
1. when the station specified in parameter is not in RUN mode,
2. when the station specified in parameter is in error,
3. when data block’s communication status specified in parameter is unstable,
The link trouble will be On if one of those conditions 1,2 and 3 above occurs. And if such a
condition is back to normal, it will be Off.

_HS1_STATE[k]
(k=000~127)
Bit
Array
HS link parameter No.1,
Block No.k’s general
status displayed
Displays the general status of the communication information for the specified
parameter’s respective data blocks.

L000100 ~
L00017F
_HS1_MOD[k]
(k=000~127)
Bit
Array
HS link parameter No.1,
Block No.k station’s Run
operation mode
Displays the operation mode of the station specified in parameter’s data block k.
L000180 ~
L00025F
_HS1_TRX[k]
(k=000~127)
Bit
Array
Normal communication
displayed with HS link
parameter No.1, Block
No.k station
Displays the communication status of parameter’s data block k to check if normal as
specified.
L000260 ~
L00033F
_HS1_ERR[k]
(k=000~127)
Bit
Array
HS link parameter No.1,
Block No.k station’s Run
error mode
Displays the communication status of parameter’s data block k to check for any error.
L000340 ~
L00041F
_HS1_SETBLOCK
[k=000~127]
Bit
Array
HS link parameter No.1,
Block No.k setting
displayed
Displays the setting status of parameter’s data block k.
[Table 1] List of communication flags based on HS link number
K as a block number is displayed through 8 words by 16 for 1 word for the information of 128 blocks from 000 to 127.
For example, block information of 16~31, 32~47, 48~63, 64~79, 80~95, 96~111, 112~127 will be displayed in L00011, L00012,
L00013, L00014, L00015, L00016, L00017 from block 0 to block 15 for mode information (_HS1MOD).
HS link No. L area address Remarks
2 L000500~L00099F Compared with HS link of 1, other HS link station number’s flag address will be simply calculated as
follows;
∗ Calculation formula: L area address = L 500 x (HS link No. – 1)
In order to use HS link flag for program and monitoring, use the flag map registered in XG5000 for convenient
application.
