i want to send modbus data "TOGOX" at the first of block, so Brain of mach3 should read the registery of "TOGOX" when  "ISMOVING" contact in brain is activated or block should start when "TOGOX" is read .
how can i do so in mach3 plc?

The Mach3 Modbus is NOT synced it sends and receives WHEN it can.

also, you can't send "directly" at least, floating point numbers over modbus.

tanks for replay and sorry for my english language .
the floating point is not my problem, because i multiply it in 1000 and send.
now i know that modbus sends data in a timer interrupt of mach3 engine, so i'm working on plugin writing in VS2008 and sed data to a electrical node with ethernet connection .
if you wish to take part in it, make me happy.
