 Inter-controller Communication |
| The FB Series has a second communication port (COM2) for inter-controller
communication. It achieves more precise cascade control and ratio control
by sending data via digital communication while conventional cascade controllers
send data to slave controllers by analog signal with less resolution. |
| Temperature Ratio Setting |
| If the master controller changes the control set value, the slave controllers
will also change the set values by following preset ratios to the master. * Up to 32 controllers with 16 groups can be configured. |
| Cascade Control |
| It is effective when a thermal time-delay exists between the heat source
and a control point. A maximum of 30 slave controllers can be connected
to one master controller. |
| Group RUN/STOP Function |
| When RUN/STOP mode is changed on one controller in a group, the mode of
all the other controllers in the same group will be also automatically
changed. *Up to 32 controllers with 16 groups can be configured. |
