The port type is determined by the DIP switch settings on the back plane pcb and the setting is
reflected in the message on the screen. The description changes to reflect the setting when the port is
set to RS232. This is particularly useful when determining the settings already in place.
For each serial port, set the Baud Rate and Parity as required. The speed may be varied between
2400 and 115,200 baud, the parity may be Odd, Even, Zero or None.
The Ethernet port IP Authentication needs to be set when internet control over the web is being used.
On a private Ethernet network it is unlikely that authentication will be required.
Once the serial port settings match the system requirements for communication to the host system
they must be sent to the master station CPU module. Click on
save settings
to send the values to the
module.
The
modbus message
button opens up a page where messages can be created and sent to the
master station, one at a time. The reply is shown and can be examined to ensure that the expected
performance is being obtained. Note that these messages are sent over the Ethernet link using
Modbus TCP and not over the Serial link and therefore do not test all the serial port settings.

Setting the IP Address
The IP address for TCP/IP and Modbus TCP communication is set on the
Network
page.
The MAC ID for each Pakscan P3F CPU module is different, but fixed at time of manufacture. The IP
address and Netmask can be altered to suit the individual application and match the needs of the
network.
Once the desired values have been set, click the
save settings
button to download the values to the
Master Station CPU module. When the IP address is changed, the comms link will fail when the new
Fig 63: Network IP Address set up page.
