3.23 Resetting the outputs on STOP or HALT (PCD2 only)

A jumper can be used to configure whether the outputs should all remain in their cur-

rent state in a STOP or HALT state, or be reset.

The jumper in question is written to by RO or ROE (Reset Output Enable), and has

two positions:

Position Behaviour

RO/ROE All outputs are reset in the STOP and HALT states

not RO/

ROE

The outputs remain unchanged in the STOP and HALT states

(factory setting)

When the user program is downloaded with PG5, there is interaction between the

PG5 options and those of the RO jumper:

The outputs are only retained if the jumper is in the “not RO” position and the “Do not
clear Outputs on download or restart” option shown below is activated. In all other
cases, the outputs are reset.
