Hello everybody.

For an aplication, I am using RSL5k SFC programming language in order to execute some sequences of several processes.

The HMI is being developed using RSView SE 4.0 and I need to add some displays where the sequences are started and monitored. So far, i have made a simple display whith a button that initializes the sequence and a multistate indicator that reads from a plc TAG the actual step of the SF Chart. Actually, within each step of the sequence, I am writing an INT variable ("SQ_STEP") that indicates the number of step, so with this tag, I use the multistate indicator to describe that step in the HMI.

Anyway, does anyone have another way to do this, maybe easily or more complete or using SFC tags?

Thanks!

Yes, you can reference the various elements of each SFC step tag directly in RSVIEW tags.

eg Step1.X


There are several different kinds of SFC tags.
The elements of a SFC_STEP tag are
.STATUS
.X
.FS
.SA
.LS
.DN
.OV
.AlarmEn
.AlarmLow
.AlarmHigh
.Reset
.T
.PRE
.Tmax
.Count
.LimitLow
.LimitHigh

An SFC step action tag SFC_ACTION elements are
.Status
.A
.Q
.PRE
.T
.Count

An SFC stop tag SFT_STOP elements are
.Status
.X
.Reset
.Count
