Station Address
setting
The station address under which the unit is accessed on the bus can be assigned through the
slide switch S1. Each address shall be assigned only once.
The slide switch S1 is binary coded. The setting of the station address is carried out according
to the scheme shown in the table. Switch position: no = left, yes = right.
The address 85 is set in the following figure.
no yes

Function Description
Communication with the processor
Communication between the host system and the processor takes place using a fixed proto-
col sequence. Data integrity from the control to the processor and vice-versa is indicated by a
control bit. This bit is used to implement a handshake between the control and the processor.
Following is a simplified representation of the sequence of a job sent from the control to the
processor:
1. The control sends a command designator to the processor together with the associated
command parameters and sets a bit (AV bit). This bit indicates to the processor that the
transmitted data are valid and that the job is now beginning.
2. The processor takes the job and sets a bit (AA bit), which indicates this to the control.
3. If an additional exchange of data between the control and the processor is required to
carry out the job, each uses a bit (TI bit and TO bit) to indicate that the control / processor
is now ready for additional data exchange or has accepted the received data.
4. Once the processor has carried out the job correctly, it sets a bit (AE bit).
5. Once the control has accepted all the important data, it indicates this to the processor by
resetting the bit that was set at the beginning (AV bit).
6. The processor now in turn sets all the control bits that were set during the sequence
(AA bit, AE bit) and is ready for the next job.
