3.8 Error Messages

The SIPLACE provides standard Stream 9 messages to report SECS-II errors. See 4.9

"SECS Message Detail" for detailed description of these messages:

{XE "S9F1"}S9F1 {XE "Unrecognized Device ID"}Unrecognized Device ID

{XE "S9F3"}S9F3 { XE "Unrecognized Stream"}Unrecognized Stream

{XE "S9F5"}S9F5 { XE "Unrecognized Function"}Unrecognized Function

{XE "S9F7"}S9F7 { XE "Invalid Data"}Invalid Data

{XE "S9F9"}S9F9 { XE "Transaction Timeout "}Transaction Timeout

{XE "S9F11"}S9F11 {XE "Data Too Long"}Data Too Long

3.9 Clock

The SIPLACE contains Clock/Calendar hardware, by which it knows the current date and

time.

The Host can send {XE "S2F31"}S2F31 to set the Equipment's Clock/Calendar

hardware.

The Host can send {XE "S2F17"}S2F17 to read the Equipment's Clock/Calendar

hardware.

The Operator can initiate a Date/Time request from the Host. The Equipment will send

S2F17 to the Host and will set its clock according to the data in the S2F18 reply.

3.9.1 Related Variables

material movement. For a more complete description of these variables, see "Appendix

A -- Variables".

3.10 Spooling{XE "Spooling"}

When the SECS link between the Host and the SIPLACE goes down (RTY error on the

Equipment side), the SIPLACE will spool appropriate messages so that the Host can

read them once the link comes back up (after a successful Connect Request

transaction).

The Host can set spooling attributes on the SIPLACE by setting certain Equipment

Constants with the S2F15/16 transaction.

The Host can define streams and functions of messages to be spooled through the

S2F43/44 transaction. Stream one (S1Fx) messages are not eligible for spooling. The

Host can also disable spooling for messages through this S2F43/44 transaction. Stream

9 messages are not spooled.

The Host may read spooled messages or purge the Equipment's spool through the

S6F23/24 transaction.

3.10.1 Word of Caution

If the Host does not intend to use the spooling features of the Equipment, the Equipment

Constant ConfigSpool (VID 66) should be set to zero. Setting this EC to zero disables

the spooling feature. If this is not set to zero, and the Host does not support spooling,

the SECS connection with the Equipment will be crippled. This happens because of the

following:

1. When spooling becomes active (transmission error), the Equipment will not send non-

stream 1 primary messages to the Host. That is, it will not send, events, alarms,

process programs, terminal display, etc.

2. When spooling becomes active, the ONLY way to deactivate it is to read or delete the

spool from the Host. In complying with the GEM standard, he Equipment does not

have the ability to reset its spooling state.

3. Therefore, if your Host does not support spooling and spooling becomes active, you

will never again receive non stream 1 messages from the Equipment. If this occurs,

you will need to use a Host simulator such as SECSIM to delete the spool.

If the Host does not intend to use the spooling features of the SIPLACE, {XE

"CONFIGSPOOL "}CONFIGSPOOL (VID 1002045) should be set to zero. This will

disable the spooling feature and the Equipment will never transition to Spool Active

state. After a transition is made to Spool Active, the only way to get out of the state is to

read or purge the spool.

3.10.2 Spooling Sequence

Messages are sent to the spool only if the Host has enabled these messages for

spooling. This precondition will not be repeated throughout this section. Assume that

the messages referred to in this section have been enabled for spooling.

While spooling is active, the Host may initiate primary messages and the SIPLACE will

respond, if it is in the COMMUNICATING state.
