1) Run-link (_HSxRLINK)
As the whole information it shows whether High-speed link is normally executed through the user
defined parameters, whose contact will be kept 'On' if once 'On' until Link Enable is 'Off', and
also will be 'On' under the conditions specified below.
① If Link Enable is 'On'.
② If all the register list settings of parameters are specified normally.
③ If all the data applicable to the parameters register list is transmitted and received as
specified in the period.
④ If the status of all the destination stations specified in the parameters is Run and with no
error at the same time.
2) Link-trouble (_HSxLTRBL x=HS link No.(1~12))
As the whole information it shows whether High-speed link is normally executed through the user
defined parameters, which will be 'On' if Run-link 'On' condition is violated when Run-link is On,
and will be off if the condition is recovered.
3) Send/Receive (Tx/Rx) status (_HSxTRX[0..127] x=HS link No.(1~12))
As individual information it shows the operation status of High-speed link parameters on the
register list up to 128 registered items'Send/Receive information. If the Send/Receive operation
of the registered items is agreeable to the Send/Receive period, the applicable bit will be On, and
if not, it will be Off.
4) Operation mode (_HSxMODE[0..127] x=HS link No.(1~12))
As individual information it shows the operation status of High-speed link parameters on the
register list up to 128 registered items' operation mode information just like the max. register
number. If the station specified in the register item is in Run mode, the applicable bit will be On,
and if in Stop/Pause/Debug mode, it will be Off.
5) Error (_HSxERR[0..127] x=HS link No.(1~12))
As individual information it shows the operation status of High-speed link parameters on the
register list up to 128 registered items' error information just like the max. register number. The
error displays the general status of the PLC which fails to execute the user program. If the
destination station PLC is normal, it will be Off, and if abnormal, it will be On.
6) High-speed link status (_HSxSTATE[0..127] x=HS link No.(1~12))
As individual information it shows the operation status of High-speed link parameters on the
register list up to 128 registered items' High-speed link status just like the max. register number,
which synthesizes the information of the individual items to display the general information of the
registered items. In other words, if the applicable list's Send/Receive status is normal with the
operation mode of Run and with no error, it will be On, and if the conditions above are violated, it
will be Off.
