ModbusTCP write

[lsnyd0ga]

I built my first screen using the Tools such as digital panel meter and keyboard input and they both are reading and writing to "42074" location.  In a push button code I tried writing data to the same register using:
ModbusTCPCom1.Write("42074", "123") but it never puts any thing in the register.
I must be missing something... Also is there a document on the ModbusTCPCom?

Try it this way:

- Add a BasicButton to the form
- Set PLCAddressClick to 42074
- Set OutputType to WriteValue
- Set ValueToWrite to 123

Then see of that works

Ah!  that worked and in checking that I realized I was writing to 43074 and monitoring 42074.....my bad and thanks

One Follow-up. Does the Modbus driver or the Controls have an option to convert to BCD or do I do that in code?

The latest beta version allows address modifiers for BCD

42074@B

My code gives me an error when I use that format.  I just installed this software Monday. Do I need to download the Beta?  If so, where is the beta download?

That only works in version 3.99y Beta
