Hello,
I'm having a problem with the Jazz.
I want to communicate with a few Omron MX2 inverters jusing Modbus.
In the old situation i use a Omron PLC and this works ok.
Now we want to convert our machines into Unitronics powered machines.
I want to send the position,start/stop,frequention,and counter clear to the inverter.
We make some simple position tasks with this inverter so there is a encoder directly to the inverter.
So it is possible to send a position to the inverter with modbus and the inverter calculate the position.
Now a cant get any connection between the Jazz and the inverter.
I use the rs485 com port for the connection between the inverter and plc.
Here are the parameters from the Omron plc:
This is to send the frequenty to the inverter.
move/store: node nr. #1
move/store: function code #10
move/store: number of bytes &7
Move/store : register #1
move/store : aantal registers #1
Move/store : number of bytes+data #0200
tranfer bit : #808 control word
frequenty 500 dec. uint
tranfer bit : #808 control word
frequenty 500dec. uint
Here you can download the user manual for the inverter.

Page 303 are the modbus registers.
Also a problem the registers are in Hex and i cant fill in hex numbers into the Jazz.
I hope you can help me,its the last Omron machine we built so we want to go Unitronics.
