RS485 and DH485 are not the same, I am sure someone who knows all the differences can comment about them. From my understanding RS485 is a physical standard whereas DH485 is a protocol used by Allen Bradley.

What is the BAS module connected to? You may be able to replace the unit with something that talks Ethernet.

Are you writing your logic in ladder 2 or another ladder, if it is in another ladder then you will need to put a JSR(Jump to Subroutine) in ladder 2. By default ladder 2 is the only one scanned when the PLC is in run mode.

FTV version 11 lets you make version 5 .mer. I think there is a patch from Rockwell that lets you do it with FTV version 12, but it will not from the standard install. -

rymac63, it may pay to talk to your distributor as there maybe an adapter plate that lets you keep the power wiring in at the top and out at the bottom.

It sounds more like that the Comms port on the SLC is no good. If the program was lost or corrupted then the Fault light would be flashing red.

The problem with using an ethernet cable is that the 24volts on the plc socket can damage a UIC, that's why you should use the correct C13 cable as it only has 3 pairs instead of 4 pairs.

Also these symbols and descriptions are only stored in the RSLogix 500 file, so if you uploaded the program from the PLC it will not include comments, you need a copy of the original RSLogix 500 file for that.

Do you have a speed reference to the VSD, check Parameter 2 when you tell it to run, then check Parameter 1 to see what the output frequency is.

Have you set up your communication path in the runtime area for this project, when you import a PV standard this does not get done automatically you need to do it manually. -
If you download RSLinx Lite and install (it is free) you will be able to use it to see the software version of the PLC.

It looks like you are trying to write 2 to a digital (bool) tag, which you can only write a 0 or a 1 to. The tag that you are writing to needs to be an INT or a DINT, not a BOOL.

You will need to buy it from a Rockwell Automation distributer in your region.

What is the full part number of the Panel View in question? There is no free software for AB Panel Views. Alan.
