PDComm.GemFormattedProgramVerificationNegotiationInfo

Class

Describes an S7F29/S7F30 process program verification negotiation held by a GemResult.

public sealed record GemFormattedProgramVerificationNegotiationInfo

Returned by GemResult.GetFormattedProgramVerificationNegotiationInfo. The equipment prepares a negotiation with GemFormattedPrograms.PrepareVerification, sends the S7F29 inquire with GemFormattedPrograms.SubmitPreparedVerification and, after a granting S7F30, sends the prepared S7F27 report. The host receives the S7F29 and answers with GemFormattedPrograms.RespondVerification. Each flag is 1 when set and 0 otherwise.

Parameters

Name	Description
`RequestKind`	The request kind: `40` (`GemRequestKind.FormattedVerificationNegotiation`) for the inquire and grant, or `35` (`GemRequestKind.FormattedVerificationReport`) for the S7F28 acknowledgement of the S7F27 sent after the grant.
`State`	The negotiation state: `1` prepared by this equipment, `2` received by this host, `3` answered by this host.
`NegotiationTerminal`	How the inquire ended: `0` not yet or ended by a malformed S7F30, `1` granted, `2` denied, `3` timed out, `4` disconnected.
`VerificationTerminal`	How the S7F27 send after a grant ended: `0` not yet or ended by a malformed S7F28, `1` acknowledged with S7F28, `3` timed out, `4` disconnected.
`Length`	The LENGTH value of the S7F29: the encoded size, in bytes, of the S7F27 report body.
`PpGnt`	The PPGNT code (`0` to `63`, where `0` grants); meaningful when `GemFormattedProgramVerificationNegotiationInfo.PpGntPresent` is `1`.
`PpGntPresent`	Whether `GemFormattedProgramVerificationNegotiationInfo.PpGnt` holds a received or sent grant code.
`Prepared`	Whether the result describes this equipment's own negotiation rather than a received S7F29.
`Submitted`	Whether the equipment sent the S7F29 inquire.
`Responded`	Whether this host sent its S7F30 answer.
`ReplyReady`	Whether a received S7F29 still waits for `GemFormattedPrograms.RespondVerification`.
`Correlation`	The sequence number of the negotiation within its connection generation; every result of one negotiation carries the same value.

`Length`	The LENGTH value of the S7F29: the encoded size, in bytes, of the S7F27 report body.
`PpGnt`	The PPGNT code (`0` to `63`, where `0` grants); meaningful when `GemFormattedProgramVerificationNegotiationInfo.PpGntPresent` is `1`.
`PpGntPresent`	Whether `GemFormattedProgramVerificationNegotiationInfo.PpGnt` holds a received or sent grant code.
