2.4 Setting the device address and baud rate
Removing the protective cap provides access to two rotary switches for setting the
device address at the bus and a 2-pin sliding switch for setting the baud rate.
The rotary switches indicate the tens and ones places of the address selected. If the
switches are resting in the position 00 the address can be changed via the Modbus
with HR 38.
The delivery setting is 00, the PSx3xxMod reports to the bus with the address 1.
If the switches have been used to set the address (i.e. the switch setting is > 00), this
value cannot be changed via the Modbus.
If the Modbus master uses the broadcast address (= 0), each PSx3xxMod on the bus
will be addressed, regardless of the actual valid address in the device. However, no
answer is being sent by the PSx3xxMod on broadcast messages.
Switch configurations:
PSx30xMod, PSx31xMod-8,
PSx32xMod-14, PSE31xxMod-14
PSx31x-14, PSx33x-14
