Batch Signatures

A signature allows the operator to sign off on an action such as ignoring tolerance or stopping an EM prematurely.  This requires the user to provide there login/password and is recorded in the batch journal.

There are two known signature templates: Deviation and Stop.

Configuration Tags 

Configuration is done at the phase level but is reflected to the acquired EM.

PhDef.Sign{Stop|Dev}ID Int Signature Request Template ID
Each request is configured as a template in batch, that includes a description and who can sign it and if it is cancellable.
PhDef.Sign{Stop|Dev}Cancel Bool Signature Request is cancellable

 

EM Tags 

An EM cannot use a signature request by itself so it gets its directive from the phase that has acquired it.

This information is shared with the EM when the phase parameters are written as a command.

{S|D} represent a placeholder for Stop or Dev(iation)

em.C.I.{S|D}SignRqrd

C.EMCmd.Sign{S|D}Rqrd

iEM.Sts.{S|D}.SignRqrd

Bool Signature is Required
Set from phase command
em.C.{S|D}SignRqst
iEM.Sts.{S|D}SignRqst
Bool Signature Requested
em.C.I.{S|D}SignAck
C.EMCmd.Sign{S|D}Ack

iEM.Sts{S|D}.SignAck

Bool Signature Acknowledged

User signed the request

May need ack to know when to stop sending the ack or I could send until the request is removed. But then how long to I reset ack?

em.C.I.{S|D}SignCancel
C.EMCmd.Sign{S|D}Cancel

See signAck

Bool Signature Request Cancelled

May be cancelled by user which should also cancel the action.

View.SignRqstPend Bool Signature Request is Pending

Phase/Batch Tags 

Ph.RqstSign

 

Int Signature Request Template ID

Set to PhDef.Sign{Stop|Dev}ID when em.C.{S|D}SignRqst is recognized

Ph.Cmd.Signed Int Batch Signature request was signed with this Template ID

Set by Batch logic when request is signed (-1 = signature aborted)

Ph.RqstSignCan Bool The current signature request is cancelable
C.PHCmd.SIGNED Int Signature was Signed command constant
FTBatch.c.Rqst.Sign Bool Sign. Request is Pending
