5-8 8. Temperature Control Network
8. Temperature Control Network
• Using the temperature control network, the UG230 can be connected to the temperature controller
or inverter.
With RS-232C, one PLC can be connected; with RS-485, a maximum of 31 temperature
controllers can be connected.
• Data of temperature controllers connected to the UG230 can be set or monitored.
• Periodical reading/sampling of temperature controller data
When read/write memory addresses are preset on the temperature control network/PLC2Way
table, background data reading is performed at regular intervals. It is also possible to save the
read data in the UG230 internal buffer, SRAM or CF card.
• Data transfer
It is also possible to transfer data in the PLC memory, UG230 internal memory or a memory card
to the temperature controller at one time using a macro command. Conversely, data in the
temperature controller can be transferred to the PLC memory, UG230 internal memory or a
memory card at one time.
• For more information, refer to the User’s Manual <Temperature Control Network> (FEH365).
