Overview

Some SFC section(s) might also be controlled by SFCCNTRL function block(s).

If inputs DISTRANS and/or DISACT of the SFCCNTRL function block are used, this will influence the behavior of RESTORE and RESUME inputs of the SFC_RESTORE function block as described below.

DISRMOTE = 1

In case the DISRMOTE input is 1 the SFCCNTRL function block has the mastership.

After performing a RESTORE or a RESUME with the SFC_RESTORE function block the value that is present at the inputs DISTRANS / DISACT of the SFCCNTRL function block will be active.

DISRMOTE = 0

In case the DISRMOTE input is 0 the SFCCNTRL function block and remote control (SFC Animation Panel or SFC_RESTORE function block) have same level of priority.

It works as a "wired or": a TRUE from any source will disable transition / action.

To achieve a FALSE value, any source that activates it to TRUE must remove it.

In this case, control coming from the SFC_RESTORE function block has the same result as SFC Animation Panel, i.e. it is taken as the same source.

After performing a RESTORE, the chart will be in the disabled mode, nevertheless what value is active at SFCCNTRL function block.

The SFCCNTRL function block could hold it on disabled, but to enable it, SFC Animation Panel or RESUME input of the SFC_RESTORE function block must be used.
