ACCESS LEVEL DDBS

The 'Access level' cell is in the 'System data' column (address 00D0). Also the current level of access for each
interface is available for use in the Programming Scheme Logic (PSL) by mapping to these Digital Data Bus (DDB)
signals:
HMI Access Lvl 1
HMI Access Lvl 2
FPort AccessLvl1
FPort AccessLvl2
RPrt1 AccessLvl1
RPrt1 AccessLvl2
RPrt2 AccessLvl1
RPrt2 AccessLvl2
Each pair of DDB signals indicates the access level as follows:
Level 1 off, Level 2 off = 0
Level 1 on, Level 2 off = 1
Level 1 off, Level 2 on = 2
Level 1 on, Level 2 on = 3
Key:
HMI = Human Machine Interface
FPort = Front Port
RPrt = Rear Port
Lvl = Level
