No communication with PV300

[smith31]

I am still having trouble communicating with the PV300 (2711-K3A17L1). I am trying to communicate directly from my computer using a 2711-NC13 cable that I soldered together myself and verified all the connections (no shorts, broken wires, etc). I used the pinout given by AB (publication 2711-IN037B-EN-P) which is basically a straight serial connection with the exception that pins 1, 6, and 9 are not connected.
I have tried to download using RSLinx and without RSLinx installed directly from Panelbuilder32. Both give time out errors and ask to verify cable connections and ensure printer port is disabled.
I can communicate between my plc (micrologix 1200) and the pv300 (the old program wrote to the integer memory on the plc) so I believe the PV300 port is okay. I have also tried multiple computers and I can download to the plc through the comm1 port but still not to the PV300.
Does anyone have any ideas?

I'm sure you are aware of this but you program the PV300 model you have through the second port. The first communicates with the PLC. The second is for downloading or using as a printer interface according to the selection.

The model 2711-K3A17 only has one DF1 port. You simply have to use a different cable for communicating between the plc and your computer.

Ah - sorry - never mind.

Have you the dh485 driver set in your Rslinx tree? If yes, you must delete that driver. After, reboot your pc.

Have you check the communication screen in your panelview. Maybe you're not at the same baud rate. Put 19200 in the panelview and your com1 in the rs232 setup. Watch for stop bit and everything else.

smith31,

I believe he has the correct cable for file upload and download:



Application File Upload/Download (Direct) Cables
PanelView Standard Type Cable to Personal Computer

FROM:
RS-232 (DF1) Comm Port only
PanelView 300
2711-K3A17

TO:
PERSONAL COMPUTER (DB-9)


USE A:
2711-NC13 (16 ft/5 m)
2711-NC14 (32 ft/10 m)
2706-NC13 (10 ft/3 m)



Then depending on what PLC he is connecting too, he'll need a different cable.
Micro-1200 I believe he said:


Protocol PanelView Standard Comm Port


FROM:
RS-232 (DF1) Communication Port (9-pin)
PanelView 300 - 1400
2711-xxx16, 2711-xxx17


TO:
MicroLogix 1000, 1200,
1500LSP
CH0 (8-pin Mini DIN)
(DF1 or DH-485)
DF1


USE A:
2711-NC21 (16ft/5m)
2711-NC22 (49ft/15m)
(null modem not required)(1)



Here is what I would do:

Open up your RSS file, look at the channel config for the port that is connected to the PV300. Is it DF1? What is the Baud settings etc...make your RSLINX driver matches those in your RSS project file. Switch cables, try again...

If it is DF1, then try to use the DF1 driver in RSLINX and auto configure.
