beijer exter T70 Modbus comms

[brendanjlee]

I have done a bit more fiddling and found that the locations that the HMI is requesting are definetely double what it should be looking for. So where I ask to display 40004 it displays 40008, where I ask for 40006 I get 40012 etc etc. It still writes everything to the right spot from the same box that has the incorrect display...

Brendan,

Are you using the Beijer H-Designer software to configure your HMI?

No. I'm using Information Designer. The information says it's version 1.50 build 308 if that helps.

I have used Modbus on Exter Units successfully many times (but never with Splat).

A couple of questions to narrow things down here:

• Is the Exter panel a Modbus Master or Slave?
• Which Flavor of Modbus are you using? ASCII, RTU, TCP
• Are you using any index registers?
• Does the firmware version in the Information Designer Software match the actual firmware on the T70 (Check Menu choices Project/Properties/Operatot Terminal)
• Do you have the latest version of the modbus driver? (Menu Choice File/Update Driver/From Internet)

It could also be a bug but you should ckeck all of the above.

If you upload your application, me or someone else can see if we can find the reason for the problem.
