Host station line status
Stores the host station line status.
0: Normal
1: Data link not possible (wire breakage)
: Link special register added to the function version B or later
1 : Turns on only the bit for the head station number.
3 : Turns on the bit for the number of occupied stations.
6 : A value stored in a CC-Link Ver.2.00-compatible slave station differs depending on the hardware version of the A1SJ61QBT11.
Hardware version M or earlier: “1: Data link error occurred”
Hardware version N or later: “0: Normal”
The A1SJ61QBT11, however, cannot perform cyclic transmission and transient transmission with CC-Link Ver.2.00-compatible slave
stations regardless of the hardware version.
