7. JbuS/modbuS protocol
Reminder:
The JBUS/MODBUS protocol available on STATYS is slave and in RTU mode.
It uses the function 3 as ‘read registers and the function 6 as ‘write register’.
The slave number is set via the control panel or via the graphic touch screen.
Conventions:
The table addresses are written in hexadecimal, beginning with ‘0x.
Some PLC systems request a relative address starting from 400 (0x0190) or 40001 (0x9C41), on this address
its necessary to add the rst address of the JBUS/MODBUS table.
Frame errors management:
In case of wrong data request, the STATYS answers with the following frame error :
Error function code Error code Cause
80 + code function 1 Function error
80 + code function 2 Addresses error
80 + code function 3 Wrong data
80 + code function 6 busy
80 + code function 8 Write register error
