4. Put the CQM1-ARM21 in Protected Mode (Mode Bit OFF, then MOD
switch ON). The master will restart.
5. Prepare the AS-Interface network separately, using an addressing device
to set all slaves to the projected addresses.
6. Connect the AS-Interface power supply, cable and slaves to the CQM1-
ARM21; If all slaves have been configured correctly, their LED indicators
on the master should light, none should flash, and the CER LED should
go OFF.
If no separate addressing unit is available, the CQM1-ARM21 can perform the
task of assigning addresses to blank slaves. Since all slaves are factory-set to
address 0, they need to be added and re-programmed one by one.
1. Connect the AS-Interface cable and power supply to the CQM1-ARM21.
2. Put the master in Setup Mode (MOD switch OFF, Mode bit IR m.01 ON).
3. Define each projected slave's address and type (see 4-5-3-3,
Set_Permanent_Configuration). If necessary, set each slave's parame-
ters (see 4-5-3-7, Set_Permanent_Parameter).
4. Connect one new slave, with address 0, to the AS-Interface cable.
5. Change the slave's address from 0 to the projected value (see 4-5-3-5,
Change_Slave_Address).
6. If necessary, set the slave parameters (see 4-5-3-9, Write_Parameter).
7. Repeat steps 4-6 for all slaves.
8. If all slaves have been configured correctly, their LED indicators should
light, none should flash, and the CER LED should go OFF.
9. Put the CQM1-ARM21 in Protected Mode (Mode Bit OFF, then MOD
switch ON). The master will restart.
