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.

Maximum number of digital outputs (DO) by combinations of output (OUT1 and OUT2)
Maximum number of digital outputs (DO) by combinations of output (OUT1 and OUT2)
Yellow mark : Represents selection of digital outputs DO3 and DO4 are not available.
*1 When the instrument has two digital outputs (DO1 and DO2) and no OUT2 output, "V" type output (load: 40mA) can be specified for OUT1.
