Welcome to our series of PowerCore training videos. This video is called
the communication menu. Let's get into the menus from the front screen.
And you can go down, you can go up as well but we'll go down to the communication
menu. Hit enter, this is highlighted. The PowerCore family comes with an RS485 port
and that port can be configured for two different types of communication. The default is Modbus
but you can also drive PVA gauges off of the same port. You can't do both.
So, if you want to use our Murphy CONNECT, for instance, or somebody else's telematics and
query our Modbus map for control and status and so forth, you would leave it on Modbus.
If you want to drive some separate PVA gauges from that same RS485 port you couldn't do the Modbus
part but you could do the PVA gauges and have a separate panel someplace else in the facility that
shows oil pressure, temperature, rpm, you know, whatever you need to have.
So, it's either one of the other you can't have both. The slave address for the Modbus,
or node number we refer to it as, defaults to one that way if the folks that are doing the querying,
if it's a PLC in a big facility or something, he has different nodes he wants to query,
he'll give this the address number he wants that way when he sends a message out over the RS485
the message only goes to the right recipient, so we would only get messages
addressed to slave address one or whatever was put in here.
Serial setup. Baud rate is 19200. You can change that. That's the default.
Stopbits 1, parity is none. You can change that to parity. That's the
defaults. PV CAN light, if you're using the PVA option on the RS485 port you can have the
PowerCore turn on the backlight to the PVA gauges if you want. That defaults to off.
CAN termination is enabled. What this is is when we're hooked up to an ECU on the CAN bus
usually we are the only ones on the bus besides the ECU or on one end and the ECU's on the other
usually. In that case you need to have a 120 ohm resistor on each end of the CAN bus.
Ours is built-in, software controlled, and is enabled. However, if the PowerCore is a branch
off the CAN bus and there's already another device on the end, then you would want to turn this
CAN termination resistor off because the branches don't require it's just on each end
of the CAN bus but usually we're just we're the only ones on the CAN bus with the ECU but
you can have the other. CAN parameter map - this is similar to the Modbus map. It's the same idea
only it's accessed through the CAN port so if the telematics folks don't have RS485, they only
have a CAN port, they can hook up to the CAN port and query our CAN parameter map and get the same
type of control and display items in the map. It's disabled so if they're using the CAN parameter map
instead of the Modbus they could drive PVA gauges off the Modbus port of the RS485 if you wanted to.
The CAN bus parameter map is disabled. The baud rate is 250 kbps. You can adjust that
to different rates. That's the default. Hitting the back button we can get back
out to the main menu and that concludes the communication menu video. Thank you.
