I found it again. It's on beijerelectronics.com

I did this before, but now for the life of me I cannot find the instructions how to restore the flash drive on a T7A. It's gone dead, says I doen't have .net installed.

Also, is there a pdf manual for the actual t7a panel, not the ix developer manual but the manual for the actual hardware device?

I found it. When it's tcp, the "Default Station" is an index into the station table, default zero. When it's serial, the "Default Station" becomes the node number. Zero is not a valid node number. I changed that to 2, and now it is polling. I see the polls in my slave emulator. Now I'm getting comm ...

I changed to Modbus over TCP just to see what would happen. I also set all the tags to "always active" as you suggested. The panel sends out modbus polls at regular intervals, and the slave responds. Good. But if I change back to serial, what I see in hyperterminal is "TEST IF ECHO". It sends that o...

I have a modbus master set up on com1. I have tags mapped to addresses on the modbus master controller. The controller is enabled. The poll group is set to 500 ms. But it won't send anything out on the com port. I know I have the com port hooked up OK, because I have another program which sends to c...

Well I'll try that, thanks!

I'll give my solution. Turns out there is one register in the slave device which always changes. It is a timestamp with one-second resolution. I'll put a valueChange event handler on the tag for that register. When the timestamp changes, I'll set a timer for an absurdly long time - in my case one se...

Oh my. The thing is, my modbus slave reports 32-bit floating point numbers in pairs of registers. For example, modbus address 40001 holds the high 16 bits and 40002 holds the low 16 bits of a floating-point number. Say I have tag T1 on 40001 and T2 on 40002. If I handle valueChanged on T1, I don't k...

Say I have a modbus master controller in my t7a. Say I have tag T1 bound to modbus address 40001 and T2 bound to modbus address 40002, and I have valueChange handers on both tags. For a given polling event, assuming the values of T1 and T2 both changed, can I assume the T1.valueChange will fire befo...

I see, and can the internal flash drive be mounted on a PC over USB? Or is there a graphical file browser in the t7x? I tried vs 2008's "remote file viewer" without success.
