Communication between the temperature controller and the V series is slow (V7 series).
To speed up communications, try the following method.
The condition can also be improved as described below.
Increase the communication speed (baud rate).
When changing the baud rate, be sure to change the settings on both the V series and the temperature controller.
Setting location: V-SFT editor [System Setting] → [Temperature Controller/PLC2Way Communication] → [Temperature Control/PLC2Way]
<When multiple temperature controllers are connected>
When multiple temperature controllers are connected, activate the communication with all temperature controllers.
This eliminates recovery confirmation accesses to stations where communication is down.
<Temperature control/PLC2Way table>
Use the [Temperature Control/PLC2Way Table] without placing temperature control memory directly on the screen.
Use [Temperature Control/PLC2Way Table] to transfer the temperature control memory to the internal memory and place the target internal memory on the screen.
If [Temperature Control/PLC2Way Table] is already used, separate the table for each station.
For more information about [Temperature Control/PLC2Way Table], refer to "How to read or write data between the temperature controller/inverter and the PLC memory or internal memory at regular intervals".
