3.3. Master operations
In order to use the S4AO module as a Slave device on a RS-485
interface, it has to be configured as follow:
•
RS-485 port 1 mode (register 4010). (or RS-485 port 1
mode.(register 4017)) set to ‚1’ (Master), set transmission
mode, baudrate address, the scanning period and the
timeout (register 4011 to 4022) and update changes
(register 4016 for port 1, 4023 for port 2),
•
For each selected output, set the individual characterisitc’s
parameters (register 7620 to 7635 or their 16-bit equiva
-
lents from the group 6000/7000), the Master controlled
mode (register 4132 to 4135), the address, the register,
the timeout and the type to read (register 4136 to 4159),
•
The read value as displayed as floats in the 7600 to 7603
registers (or in their 16-bit equivalents from the group
6000/7000).
•
Eventually, set the high and low value threshold to start
the high and low value counters (registers 4104 to 4111),
and reset them (registers 4162 to 4170).
