When control method is selected for PID control (Code : F, D), output 2
is available for analog retransmissin output.
On the RB100, the event 3 output function can be specified for output 2.
The number of DO points is limited in some combinations of OUT1 and OUT2
(control output) types. |

Quick start code
Quick start code tells the factory to ship with each parameter preset to the values detailed as specified by the customer.
Quick start code is not necessarily specified when ordering, unless the preset is requested.
These parameters are software selectable items and can be re-programmed in the field via the manual. |
