Dear Sir or Madam,

Since there is no standard config data of PV750 on the ver. 2.6, we imported the standard config data from ver. 2.3 into ver. 2.6. We created the standard data from 2.3 by using 2.6 and uploaded it into PV750, however the display showed after uploading completed that this is invalid config data. From this result, we have some questions,

1) If we want to upload the config data of PV750 imported from 2.3 by using 2.6, is there any process we should have to do?
2) Can the standard config data of PV780 be uploaded into PV750 display?
3) If you have any config data of PV750 created by ver. 2.6, is it possible for you to send it to us?

Because we could not use the ver. 2.6, we used the ver. 2.3 instead to configure the config data of PV750 and tried to set up the variables in Free Form CAN Messages of Communication Ports in Environment Setup tab. We can configure the variable name, start bit, end bit, etc., but not the resolution and offset. Could you please let us know how we should configure the resolution and offset?

Your kind support would be much appreciated.

Best regards,

Toshiki Takehara

Hello Toshiki Takehara,

The PV750 is not supported by PVCS 2.6 but support will continue in PVCS 2.3, please see this post for more information:
viewtopic.php?f=7&t=704

Regarding the CAN messages, if they follow the J1939 protocol you can define them in the J1939 database and there you can set the resolution and offset but you you define them as Free Form CAN messages you will need to scale them manually using calculation events or scripts.

Dear Ksaenz,

Thank you very much for your prompt reply.

We understand that the PVCS 2.6 does not support the PV750 and we will use the PVCS 2.3 for configuration of PV750.

The CAN messages we will use do not follow the J1939 and NMEA2000. Because we are not familiar with the programming, could you please advise us how we should do to set the resolution and offset by using calculation events and scripts? If you have any sample config data and can send it to us, we would very much appreciate.

Best regards,

Toshiki Takehara

For example:

Let's say Free Form CAN message writes to a variable called CANvar.

If we have a resolution 0.5 and an offset of -10.

Create a new variable called ConvertedVar and calculation event for it like this: And add this calculation event to the "on chage" event of the variable CANvar.

Now if the Free Form CAN message writes a value of 100 to CANvar then ConvertedVar will have a value of 40.
