USER MANUAL - Z-LINK2-LO
The figure shows a typical application of the Z-LINK2-LO device in "Remote I/O" mode within a ModBUS
RTU network:
The inputs are replicated on the outputs. If the inputs are digital it is possible to negate them, if they are
analogue it is possible to scale their values. A fault condition can be used for safety requirements.
Note that an external Modbus RTU Master device is not required in this mode because the Z-LINK2-LO also
acts as a Modbus RTU Master on the bus.
ATTENTION!
-ONLY THE MODBUS RTU PROTOCOL IS SUPPORTED
-ONLY ONE PORT (RS232 OR RS485) CAN BE USED AT THE SAME TIME.
