Checking Link Data Allocation
The link data allocation is checked each time allocation (FA Link configuration) is
made or power supply is applied. If duplicate allocation is present, error occurs
(ERR LED of the module lights up) at all the stations with duplication.
In other words, if a duplicate assigned station is added to a normal system, the ERR
LED lights up at the added station. When a system with multiple assigned stations is
turned on at the same time, the ERR LED lights only for the stations that are
recognized as being turned on later. However, if duplication is with the master
station (station with station number “01”), error occurs in all slave stations (all
stations excluding the master station).
■
Precautions when Setting Station Numbers
- Note that no error will be detected and indicated by the display LED or special
relay if any station number within the range 02–32 is duplicated.
- Note that link data on the entire FA Link system will not be correctly updated if
any station number within the range 02–32 is duplicated.
■
Powering On
- Power supply may be applied to the master and slave stations in any order.
