(2) High-speed Link 2
Device IEC type Keyword Type Description
High-speed link parameter 2 normal operation of all station.
L0260 %LX416 _HS2_RLINK Bit
Indicates normal operation of all station according to parameter set in
High-speed link and On under the condition as below.
1. In case that all station set in parameter is Run mode and no error
2. All data block set in parameter is communicated and
3.The parameter set in each station itself is communicated normally.
Once RUN_LINK is On, it keeps On unless stopped by
LINK_DISABLE.
Abnormal state after _HS2RLINK On.
L0261 %LX417 _HS2_LTRBL Bit
In the state of _HSmRLINK flag On, if communication state of the
station set in the parameter and data block is as follows, this flag
shall be On.
1. In case that the station set in the parameter is not RUN mode, or
2. There is an error in the station set in the parameter, or
3. The communication state of data block set in the parameter is not
good.
LINK TROUBLE shall be On if the above 1, 2 & 3 conditions occur,
and if the condition return to the normal state, it shall be OFF again.
High speed link parameter 1, k block general state.
