6.1.4 PC(PLC) Link
- The FP-X0 supports the link system that connects the PC(PLC) link corresponding to the MEWNET-W0
(max. 16 units) with the twisted pair cables.
- In a PC(PLC) link, data is shared with all PLCs connected via MEWNET using dedicated internal relays
called link relays (L) and data registers called link registers (LD).
6.1.5 Modbus RTU
Function overview
- The Modbus RTU protocol enables the communication between the PLC and other devices compatible
with Modbur RTU. (such as our KT temperature control unit and FP-e)
- Communication is performed when the master unit sends instructions (command messages) to slave
units and the slave unit returns responses (response messages) according to the instructions.
