Title: HELP! complete access to modbus by VBscript
Post by: Alex_1976 on June 12, 2015, 05:58:29 AM

Hi, I need your help!!!

I have to read and write, in a precise sequence, some data into plugin Modbus addresses. My VFD must receive different values to kick off the boot sequence of the electrospindle. These values are to be chosen according that reading on others address. I think should then use a VBscript macro to insert an IF loop control  but the problem is that I cant find anywhere a complete documentation of reading and writing routines on the Modbus.

I also tried the way of the Brain but ... worse still!!  :(

VFD is connected via RS232 to RS485 adapter, the fully functional and tested by Mach3's Modbus serial control monitor.
