5.8 Clock

5.8.1 Host Sets Date and Time

Step SECS Message Description

1. H -> E S2F31 W Date and Time Send. The Host sends a new

Date and Time to the Equipment.

2. H <- E S2F32 The Equipment sets its Clock/Calendar

hardware and acknowledges the command.

5.8.2 Host Requests Date and Time

Step SECS Message Description

1. H -> E S2F17 W Date and Time Request. The Host requests

Date and Time from the Equipment.

2. H <- E S2F18 The Equipment sends its Date and Time.

5.8.3 Equipment Requests Date and Time

Step SECS Message Description

1. H <- E S2F17 W Date and Time Request. The Equipment

requests Date and Time from the Host.

2. H -> E S2F18 The Host sends its Date and Time. The

Equipment sets its Clock/Calendar hardware

according to the contents of this message.

5.9 Spooling{XE "Spooling"}

For all of the spooling scenarios, spooling is meaningful only when Control State

(CONTROLSTATE = 4 or 5) is "On-Line". When CONTROLSTATE is "Off-Line"

(CONTROLSTATE = 1, 2, or 3), Equipment sends only stream one primaries and SnF0

secondaries, neither of which are eligible for spooling.

5.9.1 Host Enables Spooling of Messages

Step SECS Message Description

1. H -> E S2F43 W Host requests that messages be eligible for

spooling using the following message:

S2F43 W * H -> E

<L [2]

<U1 STRID> * Msg Stream

<U1 FCNID> * Msg Fcn

...

> .

2. H <- E S2F44 The Equipment enables spooling for the

messages requested by the Host. Response

has {XE „RSPACK“}RSPACK set to zero as

follows:

S2F44

<L [2]

<B [1] 00> * RSPACK

<L>

> .

5.9.2 Messages Spooled and Transmitted

Assumption: Spool State is "Spool Inactive".

Step SECS Message Description

1. H <- E SnFn Equipment attempts to send any message to

the Host.

2. After failure to deliver message, the

Equipment assumes that the link is down, and

will start to spool all messages marked for

spooling. The first message spooled is the

collection event {XE

„SpoolActivated“}“SpoolActivated“.

3. H <- E S1F13 W Equipment attempts to establish

communications. This message will repeat

every „EstablishCommunicationsTimer“

seconds until successful.

4. H -> E S1F14 Communications established.

Communications state transits to

„Communicating“. If COMMACK is not zero,

communications are not established and

scenario proceeds at step 3.

5. H -> E S6F23 W Host requests that Equipment begin

despooling messages. RSDC is zero in this

message.

6. H <- E S6F24 Equipment indicates that it will start to send

spooled messages with return code {XE

„RSDA“}RSDA = 0x00.

7. Equipment will start to despool messages.

This process is single-threaded. That is, when

Equipment sends a de-spooled message with

the W-bit set to „1“, Equipment must be

receive the Host reply before the Equipment

will send next despooled message. If EC

„MaxSpoolTransmit“ is zero, all messages will

be transmitted. If it is set to another number,

this number of messages will be sent. The

Equipment will await the next S6F23 to send

the next messages.

8. H <- E S6F11 W The Equipment signals CEID

GemSpoolActivated. This was the first

message in the spool if it was not over-written.

9. H -> E S6F12 Host acknowledges the start of the spool

transfer.

10. Equipment will de-spool messages one at a

time from oldest to youngest until one of the

following criteria is met: 1) All messages have

been transmitted (go to step 13); or 2) When

„MaxSpoolTransmit“ is not zero, and the

messages transmitted has reached

MaxSpoolTransmit limit (go to step 11).

Some spooled messages (usually multi-block)

consist of a SECS conversation of type
