<Request electrode condition>
With this signal the following electrode conditions can be requested:
- <Initial (Start) Tipdress request>
- <Tipdress request>
- <Prewarning>
- <End of Stepper>
This signal must be active before electrode selection/ <Spot selection> becomes active.
The <Request electrode condition> signal inhibits the <Start_1> signal.
Requesting the electrode condition:
+
Initial (Start) Tipdress
request
Spot selection/(electrode no.) 5 least significant bits Electrode condition request
state signaled to outputs
Prewarning End of Stepper Tipdress request
Figure 18: Signaling of electrode conditions to outputs
NOTE
If electrode number 0 is selected with the <Spot selection> signals and a <Request
electrode condition> signal becomes high, the states of all electrodes are requested
(group signal) and signaled through the respective outputs.
If an electrode number 1 through n (n = maximum number of electrodes) is selected with
the
<Spot selection> signals and a <Request electrode condition> signal becomes
high, the state of the selected electrode is requested and signaled through the respective
outputs.
If a <Request electrode condition> signal is active for a specific electrode, the specific
electrode selection/ <Spot selection> made allows the robot to scan the state of this
electrode and acknowledge the signal.
